Kathiparai Junction is a major road junction in the Indian city of Chennai, capital of the southern Indian state of Tamil Nadu. Situated at the Alandur area, between the intersection of the Grand Southern Trunk Road, Inner Ring Road, Anna Salai and Mount-Poonamallee Road. Kathipara flyover is the largest cloverleaf flyover in India as well as South Asia.

Construction

The junction used to be a roundabout with a statue of the Indian prime ministerJawaharlal Nehru. A cloverleaf grade separator was constructed as part of the NHDP to ease traffic congestion at the junction. The structure was built at an estimated project cost of ₹486 crore (US$58 million) with an initial deadline of March 2007. It is the first of three grade separators being built on the Inner Ring Road to improve connectivity between the various National Highways radiating from the city, the other two being the one on Koyambedu junction (NH 4) near the Chennai Mofussil Bus Terminus and the one at Padi Junction (NH 205). The main span of the flyover connecting Inner Ring Road and GST Road was opened to traffic on 9 April 2008 and the entire section was opened to the public on 26 October 2008. Landscaping work worth ₹150 lakh (US$180,000) on the 40,000 sq m area will be taken up after Chennai Metro work is completed.

Kathipara Urban Square

Kathipara Urban Square, a metro rail initiative to build facilities under the clover leaf loops of the Kathipara Junction, is being developed by a private contractor. It has a bus terminal where MTC and out- station buses can halt to pick up and drop passengers, kids play area, food court, open air theater, retail shops, office space, washrooms, vehicular parking facility, kiosks, ATMs and facilities for horticulture spread across an area of 54,400 sqm.

This development is estimated to cost around ₹140 million and is funded by the Chennai Metropolitan Development Authority and implementation and maintenance will be taken care of by the Chennai Metro Rail.
