Chennai Padi ROB Widening Project Nears Completion: Traffic Relief Expected by January 2027

Chennai motorists can expect smoother travel along the busy Inner Ring Road (IRR) near Padi from January 2027, as the State Highways Department advances its ₹155-crore Padi Road Overbridge (ROB) widening project. The project covers a 1.1-km stretch and aims to reduce traffic congestion, improve road safety and facilitate smoother vehicle movement.

According to a senior Highways Department official, 94% of the department`s work has been completed. The Railways is widening the existing bridge on both sides, and the remaining road works will begin after the railway portion is completed.

Padi ROB Widening to Improve Traffic Flow

The project will widen the existing three-lane bridge and narrow approach roads to match the Inner Ring Road`s dual five-lane configuration. The stretch between Padi Junction and the bridge experiences heavy congestion, particularly near Padi railway station on the Villivakkam side, where the road narrows to two lanes.

Sharp curves near the bridge approaches have also contributed to road safety concerns. The widening project is expected to improve traffic movement and reduce bottlenecks along this important Chennai corridor.

New U-Turn Service Roads Under Padi Bridge

The project includes U-turn service roads beneath the bridge on the Padi and Red Hills sides. The Tamil Nadu government sanctioned ₹14.5 crore for these service roads in July 2025.

The new roads are expected to help residents of Villivakkam, Kolathur, Thathankuppam and nearby areas travel towards Korattur and Red Hills without depending on the congested Korattur North Junction.

Vehicles travelling to the proposed Greater Chennai Corporation amusement park at Villivakkam Tank are also expected to benefit.

Industries and Pedestrians to Benefit

Major industrial establishments along the corridor, including Wheels India, Lucas TVS and Sundaram Clayton, are expected to benefit from improved freight movement.

The proposed service roads will measure between 354 metres and 424 metres, with sections passing beneath the railway bridge. The design provides more than 5.5 metres of vertical clearance. Continuous footpaths are also planned to improve pedestrian safety.

Once completed, the Padi ROB widening project is expected to strengthen connectivity and ease daily commuting for motorists travelling through north-western Chennai.
