The two-level steel truss bridge will carry a four-lane highway on the upper level and a single track railway on a lower level.[4] The bridge with 150.12 m (492.5 ft) long 41 spans, 6.150 km (3.821 mi) total length[3] and 18.18 m (59.6 ft) width, is going to be the longest bridge in Bangladesh, the second longest in the Indo-Gangetic Plain after Bhupen Hazarika Setu in Assam and the longest over Ganges in terms of both span and the total length.[5] The highest depth of pile of this bridge is 122 metre, which is highest among all other bridges.[6] Padma Multipurpose Bridge, when commissioned, is expected to boost the GDP of Bangladesh by as much as 1.2 percent.[7]
