Kathipara Junction, Elevated interchange in Chennai, India

Kathipara Junction is a cloverleaf grade separator in Alandur, Chennai, where the Grand Southern Trunk Road, Inner Ring Road, Anna Salai and Mount-Poonamallee Road meet. Its main span links the Inner Ring Road with GST Road, and the loops carry traffic between the four arms without stopping.

The junction was formerly a roundabout with a statue of Jawaharlal Nehru. A cloverleaf grade separator was built as part of the National Highways Development Project at an estimated cost of ₹486 crore, with an initial deadline of March 2007. The main span linking Inner Ring Road and GST Road opened on 9 April 2008, and the entire section was opened by Chief Minister M. Karunanidhi on 26 October 2008.

The junction's name comes from the old Kathiparai village, and the roundabout it replaced held a statue of Jawaharlal Nehru. Today the space beneath the cloverleaf loops is being turned into Kathipara Urban Square, with a bus terminal, food court, open-air theatre and shops.

Vehicles follow lane markings and overhead signs that indicate which path leads to each road. Most lanes remain separated, making it easier to switch direction without crossing oncoming traffic.

The junction sits in Alandur, just south of Guindy, and the cloverleaf flyover is described as the largest in India and South Asia. Under its loops, the Kathipara Urban Square is being built across 54,400 sq m with a bus terminal, food court and open-air theatre.
