SN Subrahmanyan, Managing Director and CEO, L&T adds a new notch to his long list of achievements with the completion of the Rupsha Rail Bridge. The Rupsha Rail Bridge is the latest addition in a golden era of relations between India and Bangladesh. The bridge is a 5.13 km broad-gauge single-track railway bridge and has connected Khulna with the Mongla port city via a rail line. What's more, it will have a longevity of 100 years! It is a challenging engineering feat requiring specialised base grouting technology for piling work. A total of 856 pile foundations were constructed on viaduct sections and 72 pile foundations were built for the steel bridge section with an average pile length of 72m.
