The Chennai Port – Maduravoyal Expressway is a 20.6-kilometre (12.8 mi) long, six-lane, double-decker elevated expressway under construction in the city of Chennai, Tamil Nadu, India.[1] The corridor begins at Chennai Port Gate No. 10 and travels along the bank of the Cooum River till it reaches Koyambedu and along the median of NH 48 thereon till it reaches Maduravoyal. It is also called Elevated Freeway of India.[2]
An 18.3-kilometre (11.4 mi) long, 20-metre (66 ft) wide elevated road project connecting the port with Maduravoyal is under construction at a cost of ₹1,655 crore. Upon completion, this will be the country's longest six-way elevated expressway. The project was sanctioned in June 2007 when the Tamil Nadu Government gave 'in principle' approval to the National Highways Authority of India (NHAI) for the elevated expressway. The project cost then was put at ₹1,468 crore. In January 2009, Prime MinisterDr. Manmohan Singh laid the foundation stone for the project but the project was put on hold for want of environmental impact clearance.[3] The project got the environment clearance in February 2011, and during the same month, the port handed over a cheque for ₹50 crore to the NHAI as part of its contribution to the project.
The expressway starts from Gate No. 10 of the Chennai Port near the War Memorial and ends before Maduravoyal Interchange. It would run along the banks of the Cooum up to Koyambedu and would end along the Cooum near the Koyambedu grade separator. From there for a distance of three km up to Maduravoyal the elevated expressway would come up on Poonamallee High Road. There would be a total of four entry and exit ramps as part of the project. While the entry ramps would come up on Sivananda Salai and College Road, the exit points would be provided on Spurtank Road and Kamaraj Salai. The work at the Maduravoyal end began in December 2010. The project is being implemented on a build, own and transfer mode. Of the total project cost of ₹1,655 crore, ₹310 crore has been set aside for land acquisition and rehabilitation and resettlement of nearly 7,400 people living along the project area. About 1,300 people have been rehabilitated at Okkiam Thoraipakkam. Of 30 hectares to be acquired for the project, only 2 hectares belong to private owners. The project was initially expected to be completed by end of 2013.[4] However, the project has been put on hold.[5][6]
