A new 4.94km road and rail bridge in India’s northern state of Assam, the longest dual-use bridge in the country, is set to open to traffic on Christmas day.
Crossing the Brahmaputra river in the north eastern Indian state of Assam between Dhemaji district and Dibrugarh district, the Bogibeel Bridge will be India’s longest combined road and rail bridge.
The Bogibeel Bridge will have two decks, with the upper deck supporting three lanes of traffic and the lower with room for two lanes broad gauge of rail lines.
The Bogibeel is the second longest bridge over the Brahmaputra river, falling short to the Dhola-Sadiya Bridge,a road bridge 9.15km in length.
The bridge is composed of 39, 125m spans, with a welded steel truss and reinforced concrete construction.
The pre-construction studies, detailed designs and geological survey for the project was undertaken by the state-owned consultancy and project management enterprise Rail India Technical and Engineering Services.
The 18,000 tonnes of steel for the project was supplied by Essar Steel.
The foundation of the bridge was laid in January 1997 but construction only began in 2002. In 2014 the Indian Government announced a March 2017 completion date.
The bridge is now expected to open to traffic on Christmas day, but the first freight train crossed the bridge at the start of December.
