Atal Setu (Mumbai Trans Harbour Link)

For most of Mumbai's modern life the harbour was a wall: the mainland of Raigad lay barely twenty kilometres east across the water, yet reaching it meant a long inland loop through Thane and Panvel.

• Atal Setu closed that gap.
• Opened in January 2024 and formally named the Atal Bihari Vajpayee Sewri–Nhava Sheva Atal Setu, after the former Prime Minister, the six-lane crossing runs about 21.8 kilometres from Sewri on the city's eastern waterfront to Chirle, near the Nhava Sheva port complex on the far shore — roughly sixteen and a half of those kilometres laid straight over open sea.
• It was built by the Mumbai Metropolitan Region Development Authority with Japanese development assistance, and the long navigation spans use steel decks so that shipping can continue to pass beneath.
• It is India's longest sea bridge, and driving it is the closest most visitors come to seeing Mumbai from the water.
• The experience is a drive, not a walk, and the rules are strict.
• Pedestrians, cyclists, motorcycles, autorickshaws, tractors and animal-drawn carts are barred; the bridge carries cars, buses and trucks only, and stopping anywhere along the span — including for photographs — is not permitted.
• A one-way toll applies, collected electronically, and the notified rate is revised from time to time, so check the current figure before you set out.
• There are no fuel pumps, food stalls or rest rooms between the two interchanges, so fill the tank and use facilities on land.
• At a steady pace the crossing takes about twenty minutes, with the speed limit dropping sharply on the approach ramps.
• What makes it worth the detour is the view.
• Leaving Sewri the road lifts over mudflats and mangrove fringe before straightening out above the harbour, and from the deck you get container cranes, ships riding at anchor, the low green Uran hills ahead and, behind you, the city stacked along the eastern shore.
• Between roughly December and April the Sewri mudflats below the Mumbai landfall host thousands of migratory flamingos — watch them from the designated viewing area near Sewri jetty, never from the bridge.
• At the far end the road feeds into the Mumbai–Pune Expressway and the Raigad coast roads, which is why many families now use it as the opening leg of a weekend run.
• There is nothing to eat on the bridge, so plan the meal at either end.
• On the Mumbai side, the Parel, Dadar East and Matunga belt a few kilometres north of the Sewri interchange is one of the city's strongest vegetarian neighbourhoods: Udupi-style counters serving idli, medu vada, rava dosa and filter coffee, Gujarati thali kitchens, and sweet-and-farsan shops selling khaman, fafda, dhokla and jalebi.
• Many of these are long-standing pure-vegetarian houses, but Mumbai is a major seafood city and mixed kitchens sit on the same streets, so look for a clearly displayed pure-veg board and confirm at the counter before ordering — especially about egg in bakery items.
• On the Navi Mumbai side, Vashi and Panvel offer similar Udupi and Gujarati-thali options, with exactly the same check.
