As the Detailed Project Report (DPR) is ready for the elevated Project between Chengalpattu and Tambaram is ready, the National Highway Authority of India (NHAI) is expected to float tenders in 2 or 3 months after getting the report on the project from the State Government of Tamil Nadu.
Project cost:
The estimated project cost for constructing a 6-lane Tambaram-Chengalpattu elevated corridor on the Grand Southern Trunk is around Rs. 3500/- Crores. The project is expected to commence in a year!
Project Status:
Information is gathered that the Detailed Project Report (DPR) is being whetted and the last changes being incorporated. An official shared in this regard, "We are likely to call for tenders in two or three months. The basic DPR about where it should take off and land and how many arms it should have is ready. We are awaiting the opinion of the State government in this regard."
Location:
This Tambaram-Chengalpattu corridor will take off at Perungalathur and end just beyond the Paranur toll plaza.
Project Features and Facilities
· Once completed, this project will help add a carriageway to the busy stretch that allows traffic from the city to reach the southern parts of the State!
· Ramps have been planned near the new bus stand coming up at Kilambakkam, near Potheri railway station, Mahindra World City and at Guduvancherry.
· The road at present witnesses around 1.53 lakh vehicles a day. For the elevated corridor, phase I of the proposed Tambaram–Tindivanam stretch, the projected traffic in 2030 will be 63605 and in 2040 this number will climb up to 106317.
· The construction on the 28-km-long corridor which would take three years to complete, would be on a single pier along the median and since there is an eight-lane space available below, traffic diversion will not be a problem, the official explained. The widening of the GST Road into an eight-lane highway is nearing completion.
Waiver sought from Tamil Nadu State Government
A source said the NHAI had written to the State government seeking a waiver of the royalty it collects on minerals like gravel and aggregate to be used in the construction. "This would help reduce project costs and encourage contractors to come forward. If a a waiver is given, we will mention it in the tender documents."
