The work, which began in 2010, was stopped in 2012 when the AIADMK government cited hindrance to the flow of water on Cooum and was revived for the exclusive usage of the Chennai Port but after the opposition to dropping the entry and exit ramps for non-Port vehicles, NHAI came up with a new proposal for a double-tier elevated road with an upper tier exclusive for Port vehicles while the lower tier to cater to the local vehicles. The road would be a double-tier between Port and Koyambedu for the non-port vehicles with 7 entries and exits. From Port to Maduravoyal, vehicles can enter through Sivananda Salai, West Cooum river road, Binny Road, College Road and exit at Anna Arch Road and Koyambedu. From Maduravoyal to Port, vehicles can enter at Koyambedu, Anna Arch Road and Spurtank Road and exit at Spurtank Road, South Cooum Road, Gandhi Irwin Salai and Kamarajar Salai. The project will also have 3 cable-stayed bridges at Nappier Bridge, over Koyambedu Bridge and Chennai Metro Rail and over Maduravoyal Grade Separator.
