Padma Multi-Purpose Bridge Project, one of the toughest projects in Bangladeshi history, about 96.50% complete according to PM Sheikh Hasina.
The latter explained that 100 percent of the works on the access road and the service area at both ends of the bridge have been completed while the works for the construction of the carpet, overpass carpet, waterproof membrane, movement joint of the bridge main and viaduct, lamppost, aluminum railing, gas pipeline, 400 KVA electricity and railway line are underway at present.
According to Hasina, the revised cost of the Padma Bridge project is Tk 30,193.39 crore.
Padma Multipurpose Bridge is a road-rail bridge which is being constructed over Padma or Podda, which is a major river in Bangladesh and India, and the main distributor of Ganges or Ganges, to connect Louhajong, Munshiganj to Shariatpur and Madaripur, connecting the southwestern region of the South Asian country with the northern and eastern regions.
Designed by a team of experts from Northwest Hydraulic ConsultantsSMEC International, ACE Consultants, Aas Jakobsenand HR Wallingford, led by Maunsell AECOM, the New Zealand subsidiary of AECOMthe bridge is considered the most difficult construction project in the history of Bangladesh.
It is a double-deck composite steel truss structure about 6.15 km long and 21.1 m wide with a total of 41 piers with a length of 150 m. The upper deck of the bridge will carry a four-lane highway, while the lower deck will have a railway line slated for construction in the future, a gas pipeline, fiber optic cable and power transmission lines.

The Padma Bridge design aligns with the “displacement-based approach” for seismic resilience and implements seismic isolation between the superstructure beam and the pillar and foundation system. This approach allows the main components of the bridge to move relative to each other in the event of an earthquake, thereby dissipating the large forces.
Friction pendulum bearings are used to allow large relative displacements between the bridge superstructure and the bridge piers.
The project’s detailed design was awarded the 2010 Best Backup Planning System Award by the Asian Development Bank (ADB)an international development finance institution whose mission is to help its developing member countries reduce poverty and improve the quality of life of their people.
When completed, the Padma Bridge will be the longest bridge in Bangladesh and the longest over the Ganges in terms of span and overall length. It will also be a historic structure and one of the longest river crossings in the world.
In addition to the bridge, the project also includes the construction of 15.1 km of access roads, including 2.3 km on the Mawa side and 12.8 km on the Janjira side, toll booths and dredging and bank protection facilities. .
In April, the government of Bangladesh launched the process of shortlisting contractors for the construction of the bridge.
In August, the bidding process was blocked by the World Bank after alleged irregularities in the bidding process.
In October the world Bank funding for the project was suspended and later withdrawn, following which the Government of Bangladesh decided to finance the project from its own funds.
China Major Bridge Engineering Company submitted its financial proposal on April 24.
In June, the company was awarded the construction contract for the project.
In October, more than a year and a half after the start of the main construction works, the first span is installed between pillars 37 and 38.
At the end of November, the construction of all 42 pillars was completed.
The last (41st) span of the bridge was installed in December.
In August, the last road slab is installed on the span, which connects pillars 12 and 13.
In Septemberwhile virtually participating in a Doa mahfil and Quran distribution program to mark Prime Minister Sheikh Hasina’s 75th birthday at Naria Upazila in Shariatpur district, Road Transport and Bridges Minister Obaidul Quader announced that the Padma Bridge will be open to vehicle traffic before June next year (2022).
In the first week of November 2021Asphalt matting on road slabs of Padma Multi-Purpose Bridge started from Jajira end.
According to Dewan Md Abdul Quader, the executive engineer of the main bridge project, the project team will first pave 300 meters of the bridge. Basically, it will take the team at least four months to complete the entire bridge without any downtime.
“The tapestry work started from Pillar 40 of the Padma Bridge. The initial asphalt layer is 2.5 inches thick and at some point it will be 1.5 inches. It should be noted that we will also start installing streetlights on the bridge from next month,” Mr Quader said.
The progress of the physical works of the main structure of the Padma Bridge is now 95% complete while the overall construction progress of the bridge is 88.75%.
Road Transport and Bridges Minister Obaidul Quader announces that the project is ongoing and the bridge is expected to be inaugurated in June 2022 as planned.
“We have already completed the access road, and we are now undertaking the pitch casting works, the completion of which will mean the completion of the entire Padma Bridge project,” the minister explained.
