Work on one of the flyovers on Anna Salai near the new Secretariat complex will start within a few days if the government accepts the recommendation of a revised traffic study for the facility.
Consequently, the Metro Rail work on the stretch may be delayed by a few months for completion of the piling work of the flyover.
The study, conducted by the Highways Department over the last few weeks, emphasised the need for expediting the flyover project as it would be one of the crucial components for effective traffic management on the arterial road.
Most of the eight traffic intersections of the stretch from the P.Orr & Sons showroom to the CIT Nagar First Main Road junction near Saidapet covered in the study recorded traffic volume of over 10,000 passenger car units (PCUs).
Some of the intersections have a growth of over 10 per cent in traffic volume that it is expected to soon touch 10,000 PCUs, said an official of the Highways Department.
Higher order solutions, such as construction of bridges and flyovers, are usually recommended for traffic volume of over 10,000 PCUs.
Work on two flyovers proposed on Anna Salai was expected to start in August and the CMDA had sanctioned Rs.100 crore for the project. One of the flyovers would span a length of 1.9 km, between the P.Orr & Sons showroom and the Spencer Plaza junction. The other flyover would be 2.9 km in length and stretch between Anna Arivalayam in Teynampet and the CIT Nagar First Main Road junction near Saidapet.
