Rupsha rail bridge, part of the Khulna-Mongla port rail line project, will have 100-year longevity and it is a challenging engineering feat as it required specialized base grouting technology for piling work, says its project manager.
“The bridge has been constructed over the Rupsha tidal river and this was a challenging engineering feat,” Amritosh Kumar Jha told UNB.
He said everything has to be maintained properly to ensure longer longevity of the bridge and hoped that the bridge will bring multiple benefits.
Working in the navigation channel for safe movement of ships was a challenging job, said the project manager thanking all for extending support to them for successful implementation of the project.
The 5.13-km broad-gauge single-track railway bridge, taken up under India’s concessional Line of Credit (LOC), was completed on June 25.
The Rupsha rail bridge has been constructed by Indian EPC Contractor M/s L&T and has connected Khulna with the Mongla port city via a rail line.
A total of 856 pile foundations were constructed on viaduct sections and 72 pile foundations were constructed for the steel bridge section with an average pile length of 72 m.
