Two catalysts for growth

Three provinces, two highways, one aim. The N2 along the Wild Coast and the R573 Moloto Road north of Pretoria are both catalysts for sustainable local, regional and national economic development.

Both highways will confirm that transport is one of the most important enablers of growth and prosperity in South Africa. Both will bring meaningful and measurable change.

Through empowerment, training and job creation, SANRAL improves the lives of ordinary people and communities living near these roads. But the roads are also arteries of economic life, changing the local and regional economies, as well as making a national impact.

In the Eastern Cape, the N2 Wild Coast Road will directly affect the high unemployment figures in the province. It is estimated that about 5% of the almost one million provincial unemployed could gain jobs directly through the project and its spin-offs, making it one of the single most important job-creation initiatives in the province.

SANRAL’s direct job creation forecast is for 8 000 full-time-equivalent jobs over the construction period of almost five years. These jobs will not be just for unskilled labour, but will include skilled and semi-skilled jobs as well. In addition, between 32 000 and 40 000 indirect jobs will be created by sub-contractors and suppliers during the same period.

SANRAL will implement and monitor strong enterprise and community development programmes, which will enable the SMMEs to continue their businesses beyond the actual construction period, including involvement in longer term road maintenance contracts.

The new route will promote local and regional economic growth in other areas – such as manufacturing, transport and logistics, hospitality, tourism and agri-processing.

Apart from private sector involvement, provincial and local government departments are ensuring that there is proper coordination of development initiatives. These are coordinated by the premier’s office and linked to agriculture and agri-processing in the Wild Coast Special Economic Zone, the ocean economy and other rural and local development initiatives.

Clearly this is not only about local job creation. It is a catalyst for sustainable local, regional and national economic development.

The upgrading on the Moloto Road will have further-reaching consequences than the usual SANRAL interventions – assisting local communities, road safety programmes, skills training, job creation, contracting SMMEs. It will help to unlock the economic potential of the mineral belt along the Waterberg.

The Moloto Road (the R573) carries 150 000 commuters daily and is a vital route for the local economy and for people travelling to and from work. When upgraded, this dangerous road will be safer for motorists, bus and taxi passengers as well as pedestrians. It will stimulate economic activity along the route, improve access to markets for small farmers and make it easier for tourists to get to the many popular game reserves.

The upgrade is part of the Moloto Road Development Corridor, which includes much-needed investment in passenger rail to make available safer, faster and more accessible connections between the three provinces through which the R573 runs: Gauteng, Mpumalanga and Limpopo.

Because of the vastness of this developmental thrust (estimated at R34bn) the positive impact will be felt wider than just the immediate Moloto Road communities. The regional and national economies are bound to feel the direct impact of this enormous investment.

Along the Moloto Road itself, SANRAL will do what it always does – create jobs. The breakdown of estimated job opportunities over a five-year period across the three provinces is significant:

  • Gauteng            6 250
  • Mpumalanga     3 250
  • Limpopo            3 000

That’s a total of 12 500 jobs just locally.

At a time when the economy has slowed down – making job creation and boosting SMMEs more difficult – the major SANRAL construction projects along the Wild Coast in the Eastern Cape and the Moloto Road north of Pretoria will be making an impact way beyond the local and even regional economies.

They are nationally important, true enablers of economic growth.

Toll roads need to balance saturation levels

N_ROUTE 2nd QUATER_LEAD 2

The amount a road user is willing to pay for a toll is directly linked to their available budget and the value of what they are paying for.

Should the balance tip against the perceived value of travel time saved, a toll saturation level is reached, an Australian academic, Prof David Hensher, recently told the Middelburg Chamber of Commerce and Industry.

Prof Hensher, the Director of the Institute of Transport and Logistics Studies at the University of Sydney, was speaking at a Transport Forum organised by the Middelburg Chamber.

He said the value of travel time saved is used to endorse the cost of toll fees, compared with the time travelled on “free roads”. Once saturation levels are reached, commuters start to avoid a toll road which, in turn, increases the traffic on the alternative free roads.

SANRAL’s Manager: Toll and Traffic, Alex van Niekerk, told the Forum that SANRAL has implemented an international standard for the e-tag system instead of a particular system, thus ensuring the most cost-efficient scheme.

Responding to a question from the audience, Van Niekerk said local discounts should apply for e-tag users, as the toll concessionaire is in the process of discontinuing the toll card system. He undertook to refer local concerns about discounts to Trans Africa Concessions for action. The situation will be monitored to ensure local users receive the applicable discounts.

In his presentation, Prof Hensher said that many concessionaires expect a return on their investment within the first year. But in practice, it only starts yielding a return after 10.

Van Niekerk told participants that SANRAL was established in 1998 and that the SANRAL Act allows for electronic toll collection and the issuing of toll concessions. Subsequently, three public-private partnerships were implemented.

National interoperability was introduced to enable road users to use the same tags on the entire toll road network. All transactions are conducted through a central Transaction Clearing House. Interoperability has been available on the N4 – which links Gauteng to Mozambique, past Middelburg, since March 2017.

Van Niekerk said road funding is a major challenge facing South Africa, to finance existing maintenance backlogs and provide for the expansion of the road network. Roads compete with other basic infrastructure and social services for funding from the national treasury and if tolling is not available as an option, it will have a negative impact on the country’s potential growth.

Road Freight Strategy approved by Cabinet

South Africa’s new Road Freight Strategy will create a better environment for the transport and freight industries and contribute to the upward trajectory of the country’s economy.

The strategy was approved by Cabinet in May and unveiled by Minister of Transport Joe Maswanganyi.

Once implemented it will enable South Africa to achieve the best international standards of road-freight operations through an integrated regulatory and operational framework.

Speaking after Cabinet adopted the plan, Phumla Williams, the acting Director General of the Government Communication and Information System (GCIS), said the country has been integrated into the global economy and the volume of trade via road freight has grown substantially.

The transport industry plays a leading role in contributing to the country’s economy and is a significant factor in South Africa’s trade influence, domestically, in the region and internationally. “Freight logistics is a major factor and stimulus into how South Africa does business,” she said.

The implementation of the recommendations contained in the strategy will contribute to:

  • More efficient enforcement
  • Higher levels of road safety
  • Improved protection of infrastructure, and
  • A reduced impact on the environment

It will also introduce an integrated framework of quality-regulated competition, which will enable the road-freight sector to better serve the needs of the South African economy.

The strategy will ensure that the transport and logistic sectors support effective regional integration and the development of trade within the Southern African region. It responds to the need for the harmonisation of standards and the liberalisation of transport that will promote effective cross-border trade.

South Africa is part of the Southern African Development Community (SADC) and is party to the drive for the liberalisation of interstate transport and the promotion of regional trade. SADC contributes to a tripartite initiative with two other regional bodies – the Common Market for Eastern and Southern Africa and the East African Community – to harmonise quality regulation in the road-freight sector.

 

Promotion of regional trade

The strategy highlights the urgent need to introduce an Operator Registration System that will address problems such as substandard operators, unlicensed and unroadworthy vehicles that are the major contributors to pollution and high accident rates.

Williams said the strategy creates a better environment for the transport and freight industry to thrive in and contributes to the upward trajectory of the country’s economy. “Our national competitiveness will be enhanced through the promotion of regional trade integration and improved cross-border transport efficiency.”

Transport economist Andrew Marsay told the publication Freight and Trading Weekly that the strategy was “a positive development”. He noted that it tended to focus more on the “negative externalities” of road freight – such as accidents, pollution and road damage – rather than on positive externalities, such as the facilitation of business and the flexibility of response to market needs.

Loskop Dam construction to finish this year

Loskop Dam Nature Reserve is a major tourist attraction in the Mpumalanga region.

An important route towards Loskop Dam, a major attraction in Mpumalanga, is being rehabilitated. It is due to be completed on time.

The South African National Roads Agency (SOC) Limited (SANRAL) led the project and it is expected to be finished in August, at an investment of R404-million.

This road is an important link to Loskop Dam Nature Reserve, a major tourist attraction in the region. It is home to more than 70 species of wildlife – including buffalo, leopard, and white rhino.

It is also strategically important because it links Middelburg with other key mining centres, namely Witbank and Burgersfort, so there is a high volume of commercial and abnormal truck traffic.

Residents of Groblersdal in Mpumalanga will finally have some peace, following months of frustration as a section of the N11, between Middelburg and Loskop Dam, was rehabilitated.

Construction on section 10 started in February 2015 and there have been no delays on the project.

SANRAL project manager Riaan Oerlemans said: “About 90 blasts have been conducted successfully. Thirty-six were for subsoil – found below the top soil, it consists of minerals such as sand, clay, gravel and rock, depending on the location.”

The project has employed more than 165 locals and a total of 22 subcontractors were used in the project as part of SANRAL’s community development initiative.

Congestion relief in one year

bottelary-road-r300-interchange-1
The R100-million project was prioritised to alleviate congestion and the frustration endured by thousands of motorists in Kuils River, Brackenfell, and surrounds.

In March, the South African National Roads Agency (SOC) Limited officially opened the new Bottelary/R300 interchange, a year after breaking ground.

This was done in partnership with the Western Cape government and the City of Cape Town.

The R100-million project was prioritised to alleviate congestion and the frustration endured by thousands of motorists in Kuils River, Brackenfell, and surrounds.

The City, province, and SANRAL, who purchased the land for the construction, each contributed one third of the project value. SANRAL will maintain the road going forward.

Cape Town executive mayor Patricia De Lille said: “I would like to say thank you to our partners, the Western Cape department of transport and public works and SANRAL Western Cape, for working with us to deliver this massive project in such a short space of time.

“This project has confirmed how partnerships are vital to achieving progress and responding to the needs of our citizens in ways that benefit and connect them to economic opportunities.”

Western Cape minister of transport and public works Donald Grant also praised the team for completing the project on schedule and within budget.

Alternatives to alleviate congestion

Cape Town is the most congested city in South Africa, which is why the government has developed an extensive congestion strategy that promotes the adoption of flexible working hours for people making their daily commute from the suburbs to the Cape Town CBD, the use of reliable public transport alternatives like the BRT system, carpooling and working from home, where possible.

The city and the province are leading by example – piloting the flexible working hours with their staff, in a bid to reduce congestion.

SANRAL western region manager Kobus van der Walt commended this progressive approach.

“Building roads is core to what we do at SANRAL. However, there’s so much more to it. If our road infrastructure is to fit into the concept of smart cities, citizens must take some of the responsibility,” he said. “Travel demand management needs to enter the discussion.

“To really get maximum value from our road network, we as citizens need to manage the demand on our resources. The solution to congestion needs a change in mindset and a willingness to compromise and contribute, share resources and be open to alternatives.”

SANRAL remains committed to ongoing engagement and collaboration with the provincial and local governments to ensure that the infrastructure it rolls out enables citizens to access economic opportunities in our cities.

The National Development Plan (NDP)

SANRAL enhances South Africa’s National Development Plan’s (NDP) ambition to have an efficient, competitive and responsive infrastructure network.

The NDP, also known as Vision 2030, seeks to eliminate poverty and reduce inequality by 2030. According to the plan, South Africa can realise these goals by drawing on the energies of its people, growing an inclusive economy, building capabilities, enhancing the capacity of the state, and promoting leadership and partnerships throughout society.

With the NDP in mind, the construction of the new Bottelary Road/R300 interchange in Kuils River, will make it easier to travel to and from Stellenbosch, the N1, N2 and the airport.

Construction of SANRAL N2 Wild Coast Toll Road to create up to 55 000 jobs

N2-article
The N2WCTR is set to alleviate some of the pressure experienced by many as a result of this unemployment.

About 5% of the estimated 980 000 unemployed individuals in the Eastern Cape could gain job opportunities through the N2 Wild Coast Toll Road (N2WCTR).

The South African National Roads Agency (SOC) Limited (SANRAL) announced that as many as 55 000 people will be employed during its construction.

Craig McLachlan, SANRAL’s N2WCTR Project Manager said: “The Eastern Cape’s official unemployment rate stands at 28.6%, expanded unemployment extends to 44.5% and over two million grants are being paid out every month.

“As bad as this figure is, it is an average and hides even more horrifying local statistics, with certain rural municipalities such as Ingquza Hill (based around Lusikisiki, Flagstaff and Holy Cross) having unemployment figures in excess of 85%.”

The N2WCTR is set to alleviate some of the pressure experienced by many as a result of this unemployment.

“While some of the estimated 55 000 jobs to be created will ensure people that are currently employed stay employed, a significant portion will be new jobs.

“Potentially, as much as 5% of the estimated 980 000 unemployed individuals in the Eastern Cape could gain some employment through the project and its spin offs,” said McLachlan.

How the budget will be spent

Approximately 5% of the budget for the 112 kilometer greenfields section of the N2WCTR will be spent on labour. More than R400-million will be allocated to wages for unskilled, semi-skilled and skilled workers employed directly on the N2WCTR project.

A further R1.5-billion is destined for local SMMEs comprising of local contractors and local suppliers of goods and services to the road and bridge construction projects.

McLachlan said: “SANRAL’s direct job creation forecast is 1.8 million man-days or 8 000 Full Time Equivalent (FTE) jobs over the construction period of four to five years. These jobs will not just be for unskilled labour but will include semi-skilled and skilled jobs as well, including local builders, engineers, grader operators, excavator operators, welders, mechanics, foremen, drivers, and bricklayers, to name but a few.

“According to economic employment opportunity propensities indices for road construction projects, up to 25 000 additional indirect FTE jobs will be created by subcontractors and suppliers over the construction period. These indirect jobs will be derived from a variety of fields: security, plant hire, manufacturing, catering, logistics, and aggregate and hard rock products, among others, and most will be located in the Eastern Cape.”

Opening up opportunities

Adding to this, he noted the new route creates access to the Pondoland area and forms a shorter and faster link between KZN and the Eastern Cape. It will help promote local and regional economic growth in a number of alternate areas including manufacturing, transportation and logistics, agriculture, agri-processing, and tourism.

McLachlan concluded: “Tourism, particularly, is seen as a high growth potential area. The 2008 specialist tourism study done as part of the EIA report estimated that over a 10-year period post construction, an additional 674 000 tourists would be brought to the Eastern Cape as a direct result of the refurbishment of the N2WCTR.

“Such an increase will require over 1 050 new beds in the hospitality industry of which approximately 900 would be in the Transkei area. This large increase in visitors could lead to a growth in local employment figures of up to 22 450 people over the first 10 years after the route is opened.”

Freeway management of the Cape storm

FMS-1
Approximately 240 strategically placed CCTV cameras on Cape Town’s major freeways feed real-time information on traffic conditions to the Cape Town traffic management system.

The South African National Roads Agency (SOC) Limited’s (SANRAL) capacity to handle emergencies was tested during the recent storms in Cape Town on 6 and 7 June 2017.

Approximately 240 strategically placed CCTV cameras on Cape Town’s major freeways feed real-time information on traffic conditions to the Cape Town traffic management system.

This system was tested by the extreme 48-hour storm experienced in Cape Town.

The centre is operated jointly by SANRAL, the City of Cape Town, and the Western Cape government, as part of the Freeway Management System (FMS) that became operational in 2010.

“During the time that the storm battered Cape Town and surrounds, the ability to coordinate a multi-agency response proved invaluable,” said Randall Cable, SANRAL’s Engineering Manager: Operations.

A total of 132 incidents were reported with 116 confirmed freeway incidents over this period. Of this number, 104 were attended to on-scene and included:

  • 24 crashes involving 48 vehicles
  • 61 stationary vehicles
  • 2 instances of flooding
  • 5 incidents of road debris, including trees
  • 6 lost loads
  • 4 animals in the road reserve
  • 2 incidents of a criminal nature.

On occasion, a few lanes of this vital road network were closed, but cleared within less than an hour.

The average detection of incidents was less than three minutes – 00:02:51 to be exact – and the average clearance of incidents sits at 00:48:25.

Real-time information about Cape Town freeway traffic conditions are available at www.i-traffic.co.za  and on Twitter @CapeTownFreeway for more detailed information.

SANRAL giving hope to youth of Mpondoland

Nombali-1
Emergent youth entrepreneur Nombali Hlongwe is receiving a second chance in life through SANRAL’s integrated community development and skills training programme.

The South African National Roads Agency (SOC) Limited is giving young business owners a springboard through skills development and guaranteed employment opportunities in Mpondoland.

SANRAL’s community development and community access construction roads project – a spin-off programme in support of the N2 Wild Coast Toll Road (N2WCTR) – is slowly transforming the socio-economic landscape by letting the youth break the cycle of poverty, unemployment and inequality.

The SANRAL programmes are part of the community access road upgrading project for the N2 Wild Coast Highway in Alfred Nzo and OR Tambo District Municipalities.

The SANRAL integrated community development project includes 30 SMME construction businesses and new start-ups (CIDB levels 1 – 3) currently enrolled on SAQA and CETA-accredited training programmes (NQF levels 3 -5) at three learning centres in Mbizana, Lusikisiki and Port St. Johns.

The programme will also train an additional 330 individuals with civil engineering skills to help create a local labour force for the N2WCTR.

Changing lives

Nombali Hlongwe, like many youths in Mbizana, had a difficult start in life.

Nombali spoke about her life before the SANRAL scholarship.

“I was a former finance student of the Durban University of Technology,” she said. “A lack of financial resources forced me to drop out of studies. I then worked as a call centre agent for a South African cellular network in Durban. However, for personal reasons, I had to resign and return to my family home.”

Nombali, a single mother of a four-year-old son, leaves her home between 06:30 and 06:45 to walk to class to arrive on time at 08:00.

She lives with her parents, her son, grandmother and 12 other siblings in Mbizana’s Ward 23. Her dad, Sandile is a taxi owner and mom, Nofezile is a house wife, who loves to grow her own vegetables.

“When I heard about the opportunity to participate in SANRAL’s community road building and skills programme in Mbizana I knew this would be good for my future.  It would also be an opportunity for me to make a difference in my community and help create jobs,” Nombali said.

After applying and being selected by SANRAL to participate in a two-year skills development programme, she founded new start-up company, Pumlani Construction.

She believes the SANRAL project is creating much needed work for the unemployed through skills development.

SANRAL’s training programme will give Nombali the qualification she could never afford.  A year from now, she will receive a CETA accredited certificate in construction management, and the programme also includes several modules on business management which will help her to run a sustainable and profitable enterprise.

Nombali said: “We need jobs in this area. Most of the youth are unemployed, there are some who turn to alcohol abuse and using drugs because they have nothing better to do.”

Changing family lives

Other members of the Hlongwe family are also participating in the project. Nombali’s sisters hope to, one day, work in the construction industry too.

Nombali said: “My one sister is participating in a supervisory programme and my other sister will start with a foreman training programme. I am hopeful that this project will eliminate the unemployment in the area.”

The Hlongwe family is very hopeful and optimistic that through the construction projects, which SANRAL will roll out, the situation at home will change for the better.

“Nombali working in construction is going to change the situation at home. She can maybe now get me my dream house. These days there are more opportunities for women who want to work in the construction industry,” said Nofezile.

Sandile said he was glad roads were being upgraded.

“As a taxi owner, I am happy that Department of Roads and Public Works is upgrading the R61. For taxi owners, this mean that the roads we travel on will be in a better condition. I am also happy to see that jobs are being created for people in the area where there is so much poverty,” said Sandile.

Young engineers find their way in the Musina Ring Road

Zandile-1
Tshabalala, who comes from Soweto, said she is enjoying the practical training she is receiving.

The South African National Roads Agency (SOC) Limited (SANRAL) does not only build roads – it builds communities and empowers women.

Tshimangadzo Masindi and Zandile Tshabalala, two recipients of bursaries from the Department of Transport, studied civil engineering in the Czech Republic.

The two candidate civil engineers were seconded to SANRAL to gain experience and qualify as engineers.

Gaining experience

They recently started their training at the Musina Ring Road project as assistants to the resident engineer.

Masindi and Tshabalala are required to spend 18 months on site and are currently busy with the construction of five bridges as well as four in-situ culverts on the project.

Tshimangadzo-1
Masindi looks comfortable working in the field. Her immediate future plans are to work in civil engineering.

Their responsibilities include testing the concrete according to required specifications before it is cast.

After 18 months, they will spend another 18 in Nelson Mandela Bay to do design training. Only upon completion can they apply for accreditation with the Engineering Council of South Africa (ECSA).

Tshabalala, who comes from Soweto, said she is enjoying the practical training she is receiving.

“My immediate future plans include becoming a qualified engineer. I have always been a fan of property so being here feels like home to me.”

Originally from Thohoyandou, Masindi looks comfortable working in the field. Her immediate future plans are to work in civil engineering.

“With experience, later in life, I would like to see myself as an executive in engineering specialising in structures,” she said.

SANRAL Eastern Region scoops two coveted Fulton Awards

Mt-Edgecombe-Interchange---bagged-the-Infrastructure-Award
The Mount Edgecombe Interchange upgrade has changed the landscape forever and is sure to become a well-known landmark in years to come.

The South African National Roads Agency SOC Limited (SANRAL) Eastern Region has dispelled the old saying that “lightning never strikes the same place twice” by bagging two prestigious Fulton Awards conferred by the Concrete Society of Southern Africa.

The N2/M41 Mount Edgecombe interchange under construction at Umhlanga, north of Durban, won the Fulton Award in the main “Civil Engineering Structure greater than R100 million” category given for initiatives where totally new materials, techniques, technologies, applications, designs, and/or concepts, using concrete as the principal material, have been developed or utilised.

And if that accolade is not enough to brag about, SANRAL’s Eastern Region went on to jointly win the Fulton Award in the “Innovation in Concrete” category for the reinforced concrete Van Zyl Spruit Bridge on the N1 freeway between Trompsburg interchange and Fonteintjie in the Free State.

SANRAL Eastern Region also won a Fulton Award in the prestigious category “Civil Engineering Structure greater than R100 million” in 2015 for the uMgeni Interchange project.

Logashri Sewnarain, SANRAL Eastern Region Manager, said the two latest awards were a reflection of the high standard of work on SANRAL projects and the ability to keep up with ever-evolving economic, environmental and aesthetic demands.

“The award for Mount Edgecombe interchange is particularly significant because it shows that despite the many challenges being faced, it is still possible to produce world-class infrastructure.

“The accolades are testimony to the fact that we can hold our own in civil engineering excellence when competing in the national and international arenas and such recognition is much appreciated by everybody involved in the projects.”

The awards

The Fulton Awards began as a tribute to the late Dr Sandy Fulton for his outstanding contribution to the understanding of concrete, its development, and improvement.

Dr Fulton was unquestionably one of the more prominent figures of the international concrete industry with impressive achievements in research contained in 35 published papers.  He left a legacy of scientific and technological advances in the construction industry.

The award is made symbolically to the structure and is presented to the entire team responsible for its construction, including the owner/developer, all professionals, and the contractors.

The Mount Edgecombe Interchange upgrade has changed the landscape forever and is sure to become a well-known landmark in years to come.

A concrete testament

The interchange as it stands may be considered a testament to the ability of concrete to deliver infrastructure needs on the largest scale.  Constructing one of the longest structures ever built in South Africa over one of the busiest intersections in KwaZulu-Natal successfully, without ever closing any of the roads permanently, bears testimony to the success of the selected construction methods and materials.

The judges’ citation stated: “This project showcases the use of concrete in civil engineering infrastructure in that it encompasses nine new road bridges, one new pedestrian bridge, nine mechanically-stabilised earth walls and three soil nail retaining walls.

“It features three simultaneous incremental launches with a combined deck that exceeds 1.5km, the longest incrementally-launched viaduct in the southern hemisphere, and three incremental launches being constructed simultaneously.

“This is a South African first. It was conducted under difficult conditions having to maintain the requirements of the heavy existing traffic demands within a congested site.”

A first in South Africa

Van-Zyl-Spruit-Bridge---at-90-metres,-it-is-one-of-the-longest-integral-bridges-in-the-world
The design is more complex than a conventional bridge as it involves soil-structure interaction.

The Van Zyl Spruit Bridge is unique in that it is the first long integral bridge in South Africa and, at 90m, one of the longest integral bridges in the world.

The design is more complex than a conventional bridge as it involves soil-structure interaction. The five-span road bridge has a continuous deck consisting of two spline beams, fully integral with the abutments and piers, eliminating the need for bearings and expansion joints. The intermediate supports consist of pairs of reinforced concrete piers, one under each spine of the deck and the same width as the spines. The end supports are full height reinforced concrete integral abutments with integral transition slabs.

In making the award for the Van Zyl Spruit Bridge, the judges’ citation stated: “The innovative use of integral bridges allows savings in materials, no capital cost for bearings and joints, lower maintenance costs, more durability and makes concrete bridges more competitive.

“In addition, the installation of over 500 sensors in the bridge structure which are being logged automatically every 15 minutes to detect and quantify trends in strain, temperature, tilt and earth pressure, makes this one of the first ‘smart’ bridges in the country.

“The data obtained from these sensors will contribute to a better understanding of environmental loading on the performance of integral bridges in South Africa and encourage more widespread use of integral bridges.”
