Redevelopment of Chandmari Rail Over Bridge to streamline connectivity across Howrah.

Vide a Press Release:2025/02/46, Eastern Railways, Howrah Division has shared an exemplary feat:

The redevelopment of the Chandmari Road Over Bridge (ROB) is a significant step forward in modernising Howrah’s transportation infrastructure. Replacing the existing 1933 Bow-string girder bridge, the new 4-lane Cable-Stayed Bridge is set to enhance connectivity, reduce traffic congestion, and improve safety for both commuters and pedestrians. This state-of-the-art structure is designed to meet current and future transportation needs, ensuring efficient movement of goods and vehicles in one of Howrah’s busiest areas.

The new Chandmari Rail Over Bridge will feature a 134-metre main span, the longest of its kind in the region, and a back span of 66 metres. The central pylon will stand at an impressive 81.381 metres, supported by 27 cables on each side, ensuring the bridge’s strength and durability. The total width of the bridge will be 26.41 metres, including footpaths for pedestrian safety, while the carriageway will be 15 metres wide, accommodating four lanes of traffic. Additionally, the increased vertical clearance of over 6.5 metres will provide ample space for the safe passage of vehicles and goods beneath the bridge, a significant improvement over the existing clearance of 5.1 metres.

Construction work on the new bridge is progressing as planned, with night blocks scheduled for the launching of each segment. A total of 36 night blocks will be used for launching, and the project is expected to be completed by May 2025. The segments are being launched in stages, with non-block days allotted for stressing cables and placing bearings to ensure the bridge is built to the highest standards of safety and quality. The construction process is designed to minimise disruption to traffic, with careful planning to ensure smooth operations throughout the project.

The remaining work includes the final installation of the steel deck, crash barriers, and wearing course to improve road safety. At both ends of the bridge, the Salkia and Maidan approach roads will be restructured, including the dismantling of the old viaducts, ground improvement, and the construction of RCC retaining walls. The approach roads will be expanded, with 250 RM of new road at the Salkia end and 150 RM at the Maidan end, ensuring easy and efficient access to the new bridge.

Once completed, the new Chandmari Rail Over Bridge will provide numerous advantages, including reduced traffic congestion, improved safety features, and increased capacity for future expansion. This project is set to improve the overall flow of both road and rail traffic, enhancing Howrah’s transport infrastructure and supporting long-term development in the region.
