To make traffic junctions safer for all road users, the Mumbai Traffic Control Branch (MTCB) and the Brihanmumbai Municipal Corporation (BMC) had initiated a week-long junction improvement trial at three high-risk intersections, known as black spots, on the Western Express Highway (WEH) between December 3 to 7.

The MTCB, in collaboration with partners from the Bloomberg Philanthropies Initiative for Global Road Safety (BIGRS), began the trial project at the intersection of Western Express Highway and Goregaon Mulund Link Road (Oberoi Mall junction), the intersection of Western Express Highway (WEH) and Jogeshwari Vikhroli Link Road (HBT Trauma Care Center junction), and the intersection of WEH and N S Phadke marg (Bisleri junction)--three of the city's top 20 black spots between 2019 and 2021.
