The Chennai Bypass Road is a full-access controlled expressway that interconnects four radial Indian National Highways around Chennai, India covering a distance of 32 km (20 mi) from Perungalathur (near Tambaram) on NH-32 to puzhal on NH-16 via Maduravoyal at a cost of ₹ 4.05 billion. Constructed as part of the National Highway Development Project to decongest the city of transiting vehicles, the expressway interconnects NH-32, NH-48, NH-716 and NH-16. This expressway now forms a part of the circular transportation corridor.

There are a clover-leaf grade separator at Maduravoyal Junction and a trumpet interchange at Puzhal where the bypass phase II ends.
