100-metre-long steel bridge launched over four rail tracks

An 84-metre-long launching chemoreceptor weighing astir 525 metric tonnes was utilized for the motorboat of the 100-metre-long alloy span (weighing 1,432 metric tonnes) implicit Western Railway and Dedicated Freight Corridor Corporation of India Limited (DFCCIL) tracks.

The NHSRCL said connected Wednesday, “The span comprises 2 spans of 100 metres and 60 metres, and volition facilitate double-line modular gauge obstruction track. This important infrastructure improvement progressive the crossing of 4 large tracks — 2 Western Railway and 2 DFC tracks and an irrigation canal. The 100-metre span was launched implicit the Western Railway and DFC tracks from January 28, 2025 to February 5, 2025, portion the 60-metre span volition beryllium erected implicit the irrigation canal located adjacent to the tracks astatine the operation site.”

NHSRCL said that determination were intermittent postulation blocks connected some Western Railway and DFC tracks that were “essential to guarantee the information and precision of the span launch”, carried retired successful phases to minimise disruption to regular bid and freight services.

The 14.3-metre-wide, 100-metre-span alloy span has been fabricated astatine a Research Designs & Standards Organisation (RDSO)-approved store successful Bhuj and transported to the tract by road, the NHSRCL besides said.

“The span assembly of 100m span utilized astir 60000 Nos.(100 m) of Tor-Shear Type High Strength (TTHS) bolts designed for a 100-year lifespan. The 2 spans of the span are painted with C5 strategy coating and volition beryllium rested implicit elastomeric bearings,” the merchandise said.

Five alloy bridges — a 70-metre span successful Surat, 100-metre successful Anand, 230-metre (100+130 m) successful Vadodara connected the Mumbai Expressway, 100-metre successful Silvassa (Dadra & Nagar Haveli) and 60-metre successful Vadodara — were earlier launched connected the corridor.
