The Inner Ring Road (IRR), also known as Jawaharlal Nehru Salai or 100 Feet road (SH 2) is a major transportation corridor being developed in the Chennai Metropolitan Area (CMA) by the Chennai Metropolitan Development Authority (CMDA). It is 25.2 km long with three distinct arms viz., Northern arm, Central arm and Southern arm, connecting SH 49A (Rajiv Gandhi Salai) in Tiruvanmiyur, Velachery main road at Vijayanagar, NH 45 (GST road) at Kathipara, NH 4 at Koyambedu, NH 205 at Padi, NH 5 at Madhavaram and joins SH 104 (TPP Road) near Manali.[1]

Details of the corridor[edit]

The IRR is a 6 lane road with different modes of mass transits planned along the median in different arms. It is 30 km long with the section between OTA and Kathipara Junction (1.5 km) being shared with NH 45. The northern and central arms together form State Highway 2.

Northern Arm (12 km)[edit]

The northern arm of IRR starts from Padi Junction and joins SH 104 (TPP) near Manali. It connects NH5 at Madhavaram Junction. A part of the elevated BRTS is planned along the median of this arm. This section is being strengthened by the NHAI as a part of the port connectivity project.

Central Arm (11 km)[edit]

The CMBT in Koyambedu is the terminus for all intercity bus services from Chennai. It is one of the largest bus stations in Asia.[2]

The central arm extends from Kathipara Junction and ends at Padi Junction. It connects NH 45 at Kathipara Junction, NH4 at Koyambedu Junction and NH 205 at Padi Junction. A segment of Corridor 2 of the Chennai Metro is under construction along the median of IRR from Kathipara Junction till Koyambedu. Major landmarks along this section include Hilton Chennai, Radha Regent Hotel, Arihant Majestic Towers, Udayam Theatre, the Chennai Mofussil Bus Terminus, the Koyambedu grade separator and the State Election Commission,.
