The Ministry of Road Transport and Highways (MoRTH) has set a deadline of 18 months for completion of the widening of Chennai-Bengaluru Highway.
The project is scheduled to be completed by May 2021. Of the 326 km Chennai-Bengaluru Bypass Road (NH-48), the 61 km stretch between Sriperumbudur and Walajah Road has four lanes, while Koyambedu-Sriperumbudur Road and Walajah-Bengaluru Road have six lanes.
Earlier, the work for six lanes from Maduravoyal to Walajapet that was granted in June 2012 was cancelled in July 2016. The work from Sriperambudur to Walajapet has been awarded in two parts.
The development of the six-lane corridor between Maduravoyal and Sriperambudur is envisaged as a part of Bengaluru-Chennai Expressway. The detailed project report (DPR) has been prepared for the project.
Once the six-laning is completed, travel time from Chennai to Bengaluru is expected to reduce by 90 minutes.
