Kolkata Bus Rapid Transit System
Kolkata BRTS is a proposed bus rapid transit system taken up by KMDA. Beginning at Ultadanga, the route will cover 15.5 km running along the E M Bypass to Garia. The corridor connects major growth centres like Ultadanga, Salt Lake, Tangra Metropolitan, Anandapur, Mukundapur and Patuli township. Till date (February 2022), work is not completed with no updates from authorities. A decade worth of no advancement or updates indicates that this project was terminated in its initial stages. BRTS seems to have been overshadowed by its more glamorous kin — the metro. Corridors
