M2 Bridge Rehab on Schedule

The Johannesburg Roads Agency (JRA) would like to remind road users that the M2 motorway between Crown Interchange and Maritzburg Street is still closed for rehabilitation works. The full closure will remain in force until the end of October 2019.

 “The idea is to make sure that once all the works are concluded for the period since we started in March up until the end of October, we will be able to open the bridge,” said Acting Managing Director of JRA Mr Siya Nodu.

The closure was necessitated by the continuous monitoring and the bridge visual conditions assessment which indicated that the structural integrity of the concrete elements is severely reduced. “The budget for the work here is about R151 million and the assessment that has been done indicates that we will need an extra R60 million and that will be an additional project, it will be completed, as well, by end of October as planned,” explained Nodu

The demolition of the failed bridge structural elements is at 90% and the installation of the jacking system at Selby Bridge has been completed.  

The milling and exposing of the existing asphalt is to allow for further drainage investigation, which is currently under way. “The challenges are also with the bridge joints where the water has gotten in and so we have to refurbish them.” Long-term, we are working on a plan to ensure that the bridge maintenance throughout the city is completed, according to engineering standards and to make sure that where there are challenges, we will notify the public.

“Repairs and maintenance to these bridges do not come without challenges and getting it right is also a lengthy process,because this is so specialized. A bridge has a lifespan of 50 years and the companies that can actually do the work are committed elsewhere too and hence the slow turnaround on bridge rehabilitation.”

The overall project is on schedule and will be completed by 30 October 2019 as planned.
