Chennai High Speed Circular Transportation Corridors (HSCTC) is an urban road transit in the form of elevated concentric beltways planned for the city of Chennai. The beltways are envisaged as an elevated 2-tier system with design speed of 80 km/h. The top tier is a 2-lane dedicated corridor for the Chennai BRTS system. The second tier is a 4-lane road for 4-wheelers (no buses and autos).

Four beltways have been proposed, which cover a distance of 107.795 km. A connectivity corridor is also proposed to integrate the beltways with the ECR elevated expressway.

Beltway 1 is the outermost beltway encompassing an area of 167 km². It is formed by the following corridors.

This beltway encompasses an area of 52 km². It is formed by the following corridors.

This beltway encompasses an area of 30 km². It is formed by the following corridors.

The beltway 4 is formed by the following corridors.

These 4 beltways can be broken down into 9 corridors.

This 19 km corridor is implemented under Phase-VII of National Highways Development Project by NHAI. The pre-construction work has already begun.
