Prime Minister Narendra Modi will inaugurate Atal Setu, also known as the Mumbai Trans Harbour Link (MTHL), on Friday. The 21.8km sea-bridge, the longest in the country, will significantly reduce travel time between south Mumbai and Navi Mumbai. The bridge’s full potential will be realized once other infrastructure projects, including a tunnel, elevated corridor, and airport, are completed. The toll for the bridge will be INR 250 for a one-way trip and INR 375 for a round trip.
