Chennai traffic plan: 23-km elevated road, 15-km expressway proposed

The National Highways Authority of India is planning a 23-km elevated corridor and two expressways to ease traffic entering Chennai from southern and western districts.

One of the major proposals is a 23-km, six-lane double-decker elevated corridor between Mahindra City and the Kilambakkam bus terminus.

The elevated corridor is expected to reduce peak travel time on the stretch from about 90 minutes to 15-20 minutes.

NHAI plans to construct the elevated expressway first. The corridor could also accommodate a future Metro line on the second level.

Under the plan, NHAI will construct the central pillars, including piers and pier caps, for the Metro. The state government’s proposal for the Metro has been sent to the Centre. Metro infrastructure would subsequently include girders, tracks and electrification.

Another proposal is a 15-km greenfield expressway from Pakkam village to Paranur. The six-lane road will connect with the Kancheepuram-Chengalpet highway junction.

The proposed expressway will pass through Uthiramerur and cross the Palar river.

A second expressway is planned to improve travel from Tindivanam towards Chengalpattu and Kilambakkam. The proposed route is expected to reduce the journey between Tindivanam and Chengalpattu to around 30 minutes from about one-and-a-half hours.

Vehicles travelling from Tindivanam could reach Kilambakkam in about an hour under the proposed road network.

NHAI has also proposed widening the 68-km Chengalpattu-Tindivanam stretch into a 10-lane corridor. The proposed configuration includes six main lanes and two service lanes.

The widening project is awaiting environmental clearance because of hillock areas after Paranur.

The projects are at the planning/proposal stage, with NHAI working on the proposed road infrastructure to improve connectivity into Chennai.
