Planning and Significance

The bridge was approved by the Central Government in 1969 and built by Gammon India Limited over a period of ten years, from 1972 to 1982 with total expenditure of Rs 87.22 crore at that time. . It was built to connect North Bihar with the rest of Bihar and part of national highway 19 (NH19). . Before this bridge was constructed, Rajendra Setu, opened in 1959, was the only link to North Bihar. Since then, the Vikramshila Setu has also been built across the Ganges. Two more rail-cum-road bridges are currently under construction, between Digha and Sonepur and at Munger.

The Indian postal department issued a commemorative postage stamp on Landmark Bridges Of India: Mahatma Gandhi Setu of denomination 0500 Paise on 17 August 2007.

Engineering Details

The bridge consists 45 intermediate spans of 121.065 metres (397.19 ft) each and a span of 65.530 metres (214.99 ft) at each end. The deck provides for a 7.5 metres (25 ft) wide two lane roadway for IRC class 70 R loading with footpaths on either side. The cantilever segmental construction method was adopted to construct this mega bridge. Each span has two cantilever beams on both sides which are free to move at the ends. It has two lanes one upstream and the other downstream each with a width of around 6m. Both the lanes are also free from each other and are not connected anywhere. It was constructed by using 3 meter pre-casted parts being joined at both ends to complete the span. The Spans are connected by using a Protrusion which is free to move longitudinally also along the river flow. In upwards and downwards direction it is such that it allows vibration to transfer smoothly to the next span while vehicular movement without much discreteness.

Traffic Congestion

In recent times, the bridge has been witnessing major traffic chaos and accidents due to exceeding number of vehicles passing over it and regularly overloading the structure. Bihar Government is planning to build two Pontoon bridges in parallel to it, in order to ease traffic. Over 85,000 vehicles pass through Gandhi Setu.
