Coastal Road Promenade.

>The 70 hectares (0.70 km2) of reclaimed land left over after constructing the Coastal Road is planned to be used for green and recreational areas.

>A 7.47 km long and 20 metre wide contiguous promenade runs parallel to the Coastal Road, on its seaward side, from Priyadarshini Park to the Worli end of the Bandra–Worli Sea Link. It is twice the length of Marine Drive, which is currently the city's longest promenade.

> A total of 16 pedestrian underpasses (1 every 500 metres) between Priyadarshini Park and Worli provide access to the promenade.[25] The BMC proposes to build gardens and parks, a cycling and jogging track, public toilets, an open auditorium, a butterfly park and other recreation spaces.
