Project Description:

The main bridge of Padma Multipurpose Bridge has a length of 6150 meters, featuring an outstanding design with large-diameter steel raking pile composite foundation and epoxy-glued roadway deck - continuous steel truss composite structure. Its successful construction has increased national GDP and reduced poverty rate.

Judges Comments

With an overall length of over 6km, this long-awaited crossing provides an essential transportation and services link between the two previously disconnected parts of Bangladesh, separated by the huge Padma River. The double level steel truss with composite concrete deck slabs, carries rail on the lower level and a 4-lane highway on top. Very deep riverbend silt with excessive scour depths and the risk of liquefaction demanded an innovative approach for the large diameter raking steel piles with lengths up to 125m.
