Saraighat Bridge, Rail and road bridge in Kamrup district, India

Saraighat Bridge is a rail-cum-road bridge across the Brahmaputra at Guwahati, the first of its kind in Assam. Its 1,298-metre span carries a 7.3-metre-wide road above a railway line, with the deck 40 feet above the normal flood level. The New Saraighat Bridge, a three-lane road bridge, stands beside it.

The idea of bridging the Brahmaputra was first raised in 1910 and gained momentum during the Second World War. Construction of the Saraighat Bridge began in January 1959, carried out by Hindustan Construction Company using about 40,000 tonnes of cement and 20,000 tonnes of steel with some 8,000 workers. The bridge was completed in September 1962, and the first engine crossed on 23 September 1962. Prime Minister Jawaharlal Nehru formally opened it to passengers on 7 June 1963 and gave it the name Saraighat Bridge.

The bridge was first called the Brahmaputra Bridge; Prime Minister Jawaharlal Nehru renamed it Saraighat at the opening ceremony on 7 June 1963, held near Maligaon railway station. The name recalls the 1671 Battle of Saraighat, in which Lachit Borphukan's forces defeated the Mughals on the Brahmaputra. In October 2012, at the bridge's fiftieth-anniversary event, Governor J. B. Patnaik proposed renaming it Lachit Borphukan Bridge.

The crossing is open year-round and serves as a main transportation route between the river's north and south sides. Traffic can be heavy during peak hours, so allow extra time when planning to cross.

The newer of the two bridges was built with modern engineering standards and represents a major investment in the region's infrastructure. It demonstrates how important this river crossing remains for connecting the region's population centers.
