The 13-km elevated corridor will pass through Thiruvanmiyur, Kottivakkam, Palavakkam, Neelankarai, Vettuvankeni, Injambakkam, Sholinganallur and Panaiyur before reaching Uthandi. The project has been planned to enable seamless, signal-free travel from the OMR Tidel Park junction to Uthandi, with multiple access ramps proposed to meet local connectivity needs.

The project is being implemented by KNR Constructions Pvt Ltd under the Hybrid Annuity Model. Under this model, the State government will bear 40% of the project cost during the construction period, while the remaining 60% will be invested by the concessionaire and paid back by the government in instalments, with interest, during the operation and maintenance period. The project has a construction period of three years, followed by five years of maintenance.

The elevated corridor is being taken up by the Tamil Nadu State Highways Authority, which was constituted to implement major road infrastructure projects, including four-lane highways and expressways, through the public-private partnership mode. The project cost is estimated at Rs 2,100 crore.

Officials said the corridor, billed as the longest elevated road project in Tamil Nadu, would significantly improve safety, travel speed and commuter convenience on the East Coast Road, which has seen rapid growth in traffic volumes over the years.
