After much delayed, the six-laning of the stretch of East Coast Road from Thiruvanmiyur to Akkarai appears to be back on track, with a detailed project report completed. The six-lane stretch of East Coast Road from Thiruvanmiyur to Akkarai is likely to have dual-level grade separators and would cost the exchequer Rs 260 crore.
The highways department initially planned two grade separators at both ends of the 12km stretch with a width of 30m. In the new plan, however, officials have taken a relook at the feasibility of a grade separator at across the revenue villages of Thiruvanmiyur Akkarai village in Injambakkam, a distance of 11.4 km, will outcome in the acquisition of 4,256 square metre of land which would cost the exchequer Rs 20 crore for widening on both sides of the four-lane stretch.
On the basis of traffic survey conducted in the Akkarai Junction, it was noticed that 4947 passenger car units pass there per hour. However, the dual grade separator at Akkarai would ease traffic congestion on ECR. The proposed plan of Grade Separator is to ensure signal-free, smooth traffic to and from Sholinganallur, which is congested due to motorists heading to ECR. Grade Separator Considering the six-laning construction and exponentially growing traffic volume, the peak hour traffic is expected to reach 10,000 passenger car units (PCU) per hour in another five years.
Department mentioned that the dual level grade separator gives a long-term solution with zero conflict and though the cost is higher, which will be resulting in economical considering the future growth.
