Jamuna Bridge, more correctly called the Jamuna Multi-purpose Bridge, opened in June 1998, is the longest bridge in Bangladesh as well as in South Asia, and the 11th longest bridge in the world. It was constructed over the Jamuna River, mightiest of the three major rivers of Bangladesh, and fifth largest in the world in terms of volumetric discharge. 1998 (MCMXCVIII) is a common year starting on Thursday of the Gregorian calendar, and was designated the International Year of the Ocean. ...

The bridge established a strategic link between the eastern and western parts of Bangladesh. It generates multifarious benefits for the people and especially, promotes inter-regional trade in the country. Apart from quick movement of goods and passenger traffic by road and rail, it facilitated transmission of electricity and natural gas, and integration of telecommunication links. The bridge, stretching from tangail to sirajganj is located on the Asian Highway and the Trans-Asian Railway which, when fully developed, will provide uninterrupted international road and railway links from South-east Asia to North-west Europe.
Specification and construction
Considering the fact that the width of the main channel does not exceed 3.5 km, and after making allowances for floods, a bridge length of 5 km was considered adequate. In October 1995, one year after the commencement of physical work of the bridge, a bridge length of 4.8 km, instead of a flood-width of the river at 14 km, was finalised. This narrowing was essential to keep the overall project cost within economic viability. It has, however, required considerable river training work to keep the river under the bridge.

To withstand predicted scourge and possible earthquakes, the bridge is supported on 80-85 meter long and 2.5 meter and 3.15 meter diameter steel piles, which were driven by powerful (240-ton) hydraulic hammer. The superstructure of the bridge is pre-cast segments erected by the balanced cantilever method. Basic features of the bridge are: length (main part) - 4.8 km; width - 18.5 metre; spans - 49; deck segments - 1263; piles - 121; piers - 50; road lanes - 4; railway tracks - 2?.
Gauge The Jamuna bridge carries both broad and narrow gauge rail tracks, but it is not clear if these are two separate lines or one dual gauge line.
