Shah Amanat Bridge, the second constructed across the Karnaphuli River in Bangladesh, is the first major extradosed bridge in the country.[2] It is located along the country's busiest national highway N1. It connects the southern parts of Chittagong, Cox's Bazar, and the hill district Bandarban.[3] [4] It is named after Chittagong's 18th-century Islamic Saint Shah Amanat.
Construction of the bridge started in August 2006 and it was officially opened on 8 September 2010.[2] The Chinese construction company Major Bridge Construction, China, built the bridge. The project involved a cost of Taka 590 crore, including a foreign exchange component of Taka 3.72 billion provided by the Kuwait Fund.
The bridge is 950 m long and 24.47 m wide. It has five piers with three 200 m extradosed main spans, two 115 m side spans and a 130 m approach viaduct section.[2] Alongside four lanes for vehicles, the bridge has two 1.5 m lanes for movement of 'manual transports' like rickshaws, push carts and vans. There is also a 1.5 m walkway on each side of the bridge. The bridge has a 0.5 km approach road in the city end and one km approach road at the Patiya end.
