The construction of a second rail-cum-road bridge over the Brahmaputra River at Saraighat in Guwahati is set to commence soon, according to officials.

The project, sanctioned under the doubling of the Agthori–Kamakhya railway line by the Northeast Frontier Railway (NFR), has an estimated cost of Rs 1,473.77 crore. It was approved in the 2023–24 financial year and is targeted for completion by December 2029. Detailed estimates were cleared by the Railway Board in February 2024, with the final design and report approved in March.

"The geotechnical investigations have been completed for the design of the substructure and superstructure, and an EPC tender has been floated for the construction of the bridge, including approach roads, rail viaducts, earthwork and ancillary works. The tender is expected to be finalised soon, and construction works will be started immediately after the same," an NFR spokesperson said.

The project involves constructing a 7.062 km stretch from Agthori to Kamakhya, featuring a 1.3 km-long steel composite girder bridge. The structure will accommodate a double-line railway track on the lower deck and a three-lane roadway with footpaths on the upper deck.
