The top tier is a 2-lane dedicated corridor for the Chennai BRTS system.
A connectivity corridor is also proposed to integrate the beltways with the ECR elevated expressway.
This 19 km corridor is implemented under Phase-VII [7] of National Highways Development Project by NHAI.
A 2-lane elevated BRTS corridor is proposed along the median of the Phase II of this expressway.
A total of 15 interchanges has been proposed along the HSCTC alignment of which 3 are already under construction by NHAI.
