Detailed design of the main bridge – viaduct spans in Padma Multipurpose Bridge project, Bangladesh

The Padma Multipurpose Bridge Design Project comprises a new fixed crossing of the Padma River in Bangladesh, which will consist of a new main bridge approximately 6.15km long with spans crossing the Padma River. Viaduct spans on both sides of the Padma River support both the highway and railway traffic and lead this traffic onto the upper and lower levels of the main bridge. The length of the approach road viaducts ranges from 720m to 875m long. The length of the railway viaducts ranges from 2.36 km to 2.96 km. The superstructure of the approach road viaducts consists of precast, pre-tensioned concrete Super-T girders which will become the first Super-T girder structure to be constructed in Bangladesh.
