The upgrading of the road between Trompsburg interchange and Fonteintjie was completed at the end of November 2017, but not without challenges.
The project was undertaken because there was a need to enlarge a number of culverts or bridges that had initially been designed to handle relatively small floods.
SANRAL Eastern Region Project Manager Hugh Brooks said: “The upgrading of these structures ensured that this section was now built to handle a 1-in-100-year flood, in line with national road standards.
“It proved cheaper to build an entirely new carriageway, with larger structures, west of the existing carriageway and demolish the original carriageway.”
