The first phase of India’s Mumbai coastal road project is to feature multi-level interchanges and 18 entry and exit points.

The Rs120bn ($1.6bn) project, stretching 29.2km along Mumbai’s coast, will see interchanges built at Haji Ali, Peddar Road and Worli sea face, according to Hindustan Times.

Authorities also plan to build an underground car park close to the three interchanges to accommodate 1,625 vehicles.

Beginning at the Princess Street flyover in Marine Lines and ending in Kandivli, the first phase of the road will feature eight lanes, with two reserved for the bus rapid transit system (BRTS).

“By 2024, authorities estimate that the new road will carry 343,126 PCUs per day.”

A 9.98km road will be built from the Princess Street flyover to Bandra-Worli sea link, for which 90ha will be reclaimed. With connectors, the road will be 13.88km long.

Four entry-exit points will be built at the Peddar road interchange, while the Haji Ali and Worli interchanges will feature six and eight respectively.

The road will have a speed limit of 40km/h. Authorities also plan to install a crash attenuator to serve as crash barriers.

The 5.6km extension of the Bandra-Worli sea link to Versova will be constructed by the Maharashtra State Road Development Corporation (MSRDC). The agency working on the stretch between Versova and Kandivli has yet to be decided.

By 2024, authorities estimate that the new road will carry 343,126 passenger car units (PCUs) a day.
