The Centre and the Tamil Nadu Government have come together with a proposal to lay a 20.6-kilometre long double-layered elevated road in Chennai, connecting Madhuravoyal in the city with the Chennai Port.<br />''<br />''A Memorandum of Understanding for the key expressway project has been signed between the State Government, the National Highway Authority of India, the Chennai Port Trust and the Indian Navy on Monday in Chennai. It was signed in the presence of  Chief Minister M. K. Stalin, Union Minister of State for Road Transport and Highways General V. K. Singh and the Flag Officer Commanding of the Indian Navy for Tamil Nadu and Puducherry area, Rear Admiral Puneet Chadha among others.<br />''<br />''The major infrastructure project will have two decks and the topmost layer is meant for trucks to and from Madhuravoyal and the port while the lower deck will be for use for passenger vehicles. The lower layer will have ramps at key locations for vehicles to enter it and make an exit.<br />''<br />''The project was envisaged as a single-layered elevated road, way back in 2010 with an estimated cost of about 3,100 crore rupees. Though the works began at that time, it remained stalled with the change of government in the state. Now, it is being revived as a double-deck expressway. <br />''<br />''<br />
