40-km elevated corridor from Chennai-Chengalpattu.

The Chennai Metropolitan Development Authority has invited bids from consultants to carry out a feasibility study for a 40-km elevated corridor from Chennai to Chengalpattu along the GST Road. The elevated road will stretch along the Chennai airport on the outskirts of the city to the toll plaza near Chengalpattu. The highway is the gateway to South Tamil Nadu.

The bid document says traffic volumes are growing at about 14 per cent annually.

The stretch has only four lanes with lot of local traffic from villages on both the sides of the road with the median opening in 20 locations causing frequent traffic jam. There are nine sub-urban railway stations along the road resulting in pedestrians criss-crossing the highway. The average journey speed of this corridor is 24 kmph, which is far below the standard of a national highway.
