Atal Setu's official project facts explain Mumbai's 21.8-kilometre sea link

A Press Information Bureau release on the inauguration of Atal Bihari Vajpayee Sewri-Nhava Sheva Atal Setu records the bridge as a 21.8-kilometre, six-lane connection in the Mumbai region. The release separates that length into approximately 16.5 kilometres over the sea and 5.5 kilometres on land. Those figures provide a useful way to understand the structure: Atal Setu is not only a long elevated road section, but a route whose greater share crosses the harbour.

The announcement was dated 12 January 2024 and described the bridge's inauguration in Navi Mumbai. It identifies the project as the Mumbai Trans Harbour Link, commonly known as Atal Setu, and records a construction cost of more than ₹17,840 crore. The figures are reproduced here as the official release presents them. They should not be converted into a claim about the cost of an individual trip, because the release is a project announcement rather than a current toll or traffic notice.

For residents looking at the map, the bridge's significance lies in the connection between Sewri on the Mumbai side and Nhava Sheva in Navi Mumbai. The official announcement presents the link as an infrastructure project intended to improve connectivity. It does not provide a detailed timetable, a complete list of approach roads or a live traffic advisory. Anyone using the bridge should therefore check current operating information and road conditions separately.

The sea section also explains why the project is described in engineering rather than only transport terms. A bridge that spends approximately 16.5 kilometres over water has different construction and maintenance requirements from a conventional urban flyover. The PIB release does not provide a full technical design report, so this article does not add engineering claims beyond the published length, lane count and land-sea split.

Atal Setu can therefore be read as a regional mobility connection with a very specific physical profile. The official figures identify the scale, the six-lane arrangement and the route's division between sea and land. The release also records the inauguration date and project cost. For a current journey, drivers should rely on live notices rather than an inauguration document; for understanding the bridge itself, the PIB release provides a clear and checkable starting point.
