After eight years of construction, Bangladesh's longest bridge officially opened June 25. Crossing the Padma River, the roughly $3.6-billion, 6.15-km-long rail crossing carries four lanes of highway on an upper deck and a rail track on a lower deck.
The bridge was built by China Major Bridge Engineering Co. Ltd, while AECOM Technology Corp. secured the bridge design contract in 2009. Denmark's COWI A/S and companies that became subsidiaries handled various support roles for the Bangladesh Bridge Authority.
