Madhya Kailash Junction, Traffic interchange bridge in southern Chennai, India.

Madhya Kailash Junction is a road junction in southern Chennai where Rajiv Gandhi Salai (the IT Expressway) begins and meets Sardar Patel Road, the road linking Adyar and Kinty, forming a T. It stands at the boundary of the Madhya Kailash temple area. A trumpet interchange was proposed for the junction, starting on the IT Expressway in front of Kasturba Nagar station and running parallel to the MRTS line before splitting to join Sardar Patel Road; it was never built.

In 2007, Local Administration Minister M. K. Stalin proposed flyovers at four Chennai junctions, including Madhya Kailash on the Old Mahabalipuram Road. The schemes were to be completed by 2009, but the State Highways Department left the interchange pending. A trumpet interchange was planned to start on the IT Expressway opposite Kasturba Nagar station and run parallel to the MRTS line before joining Sardar Patel Road.

The junction is named after the Madhya Kailash temple on its edge, the landmark that gives the spot its name in southern Chennai. The Tamil name, மத்திய கைலாசம் சந்திப்பு, is the one used locally for the crossing where Sardar Patel Road meets the start of Rajiv Gandhi Salai.

The bridge functions as a main connection point for vehicles traveling between the IT corridor and residential neighborhoods in southern Chennai. Visitors should be aware this is a heavily trafficked intersection, especially during peak hours.

The junction lies 1.6 km from the Periyar Science and Technology Centre, 5.3 km from Elliot's Beach in Besant Nagar and 9 km from Marina Beach. A trumpet interchange was proposed here, starting on the IT Expressway opposite Kasturba Nagar station and running parallel to the MRTS line.
