NAVI MUMBAI, Feb. 4 -- Air travellers heading to the Navi Mumbai International Airport (NMIA) could soon reach the terminal just 10 minutes after getting off the Atal Setu, with CIDCO finalising the engineering design for a six-ramp, signal-free interchange at Shivaji Nagar in Gavhan village that will plug the Mumbai Trans Harbour Link directly into Ulwe Coastal Road. The current travel time after getting off the Atal Setu (MTHL) to reach the airport is 30-40 minutes. Once the interchange project is completed, travellers from South Mumbai heading to the Navi Mumbai airport, can expect to reach the terminal in under 40 minutes. Officials have set August 2026 as the completion target for the interchange. The Shivaji Nagar junction will be rebuilt as a high-speed cloverleaf interchange, featuring three-lane ramps, loops and slip roads that allow traffic to move in all directions without stopping at signals. Dedicated loops will allow vehicles from the Atal Setu to bypass Ulwe traffic and head to the airport. Separate connectors will handle movements of heavy vehicles between Mumbai and JNPT Port....
