An underground tunnel between Marine Drive and the Eastern Freeway has been approved by the Mumbai Metropolitan Region Development Authority (MMRDA) following a recent meeting. The 65-million-dollar tunnel should reduce travel time to 10 minutes
The 154th Authority Meeting was held in March, and among the many projects discussed, the MMDRA approved the construction of a 3.8 km long tunnel route to offer vehicular connectivity between Orange Gate, the Eastern Freeway, and Marine Drive on the Mumbai Coastal Road. It was noted that this initiative would ease rush-hour traffic. The third and longest road tunnel, with 2+2 lines, will be here. It will be built along S V P Road around 30 metres below the Grant Road and Girgaum stations of Metro 3
