Overview
- The southbound carriageway, which closes Friday from 1 am to 6 am, will route drivers off at Amarson Junction toward Stephen Church and Kemps Corner before rejoining local roads near Vinoli Chowpatty.
- Northbound traffic shut early Thursday during the same hours for the tests, with diversions via Netaji Subhash Chandra Bose Road, B.D. Somani Junction, Princess Street Bridge, Bal Bhavan, and Mafatlal Junction.
- The Mumbai Traffic Police ordered the temporary closures to test emergency systems installed along the corridor to improve incident response and protect commuter safety.
- Authorities urged motorists to plan trips in advance and expect brief delays on alternate corridors such as D.B. Marg during the early-morning detours.
- In a separate move, 102 architects asked the chief minister and Mumbai’s civic chief to halt an underground parking plan at Mahalaxmi Racecourse, arguing it would pave over one of the city’s last large flood‑absorbing grounds linked to land reclaimed for the project.
