Jamuna Bridge

The Bangabandhu Bridge, commonly called the Jamuna Multi-purpose Bridge, connects Bhuapur on the Jamuna River's east bank to Sirajganj on its west bank. It was opened in June 1998.

The main bridge is 5.63 km long with 47 main spans of approximately 100 metres and two end spans of approximately 65 metres. Connected to the bridge are east and west approach viaducts each with 12 spans of 10 metre length and transition spans of 8 metres. The total width of the bridge deck is 18.5 metres.

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 a powerful (240-tonne) 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) 5.63 km; width 18.5 metre; spans 49; deck segments 1263; piles 121; piers 50; road lanes 4; dual-gauge railway (broad gauge and metre gauge).

The main bridge deck is a multi-span precast prestressed concrete segmental structure, constructed by the balanced cantilever method. Each cantilever has 12 segments (each 4 m long), joined to a pierhead unit (2 m long) at each pier and by an in-situ stitch at mid span. The deck is internally prestressed and of single box section. The depth of the box varies between 6.5 metres at the piers to 3.25 metres at mid-span. An expansion joint is provided every 7 spans by means of a hinge segment at approximately quarter span. The segments were precast and erected using a two-span erection gantry.
