Chennai: Two new flyovers are set to be constructed to ease bottlenecks on Old Mahabalipuram Road (OMR) and allow free turns from Velachery. The unidirectional flyovers at SRP Tools Junction and Perungudi will improve connectivity for motorists travelling from Velachery towards Thiruvanmiyur, Thoraipakkam, and Sholinganallur. The 90-crore projects will run parallel to the ongoing Metro Rail construction on Corridor 3 (Madhavaram-Siruseri).The first flyover at SRP Tools Junction will be 760m long with two sharp 90-degree turns — a double-bent design. Motorists from Velachery can use a ramp to turn left, then right, and descend near LB Road in Thiruvanmiyur, bypassing signals. This will also offer Thoraipakkam-bound vehicles a signal-free right turn. The flyover will have two lanes and will run above ground, while metro rail track remains underground at this location, said T Archunan, Director (Projects), CMRL.The second flyover, at Apollo Hospital Junction in Perungudi, will be 615 metres long and 5.5 metres wide, functioning as a one-and-a-half-lane structure. It will allow vehicles coming from Velachery and Dr Ambedkar Law University to take a free right turn onto OMR, eliminating the need to halt at signals. This flyover will be built beneath the elevated metro rail viaduct, making construction more complex due to limited space on MGR Road and the need to land the ramp on the left side of OMR without disrupting straight-moving traffic.Currently, vehicles heading right take a forced left and travel nearly 500 metres before making a U-turn, causing severe congestion—especially during the monsoon. The flyovers could eliminate this detour and reduce chokepoints. CMRL officials say construction will begin after finalising bids. Since no land acquisition is required, work can begin quickly. Final designs were prepared in consultation with traffic police.However, residents fear short-term congestion will worsen during construction due to existing metro work.
