The iron bridge, weighing 240 tonnes, is five times heavier than a typical Bailey bridge and incorporates 90 tonnes of steel girders and 150 tonnes of concrete girders. This design ensures longevity and strength, allowing four rows of cars to pass alongside additional space for two-wheelers. The cantilever pedestrian walkway is specifically designed to prevent interference with vehicular traffic.
This section of the EM Bypass is among the narrowest and busiest in Kolkata, with approximately 8.8 lakh vehicles crossing daily. In contrast, the north-bound flank already features a six-lane setup with two load bridges. The widening initiative was initiated after Kolkata Police flagged severe traffic snarls caused by Metro construction activities. The Metro piers, particularly piers 284 and 285, reduced road space further, prompting several discussions to find a practical solution.
Construction of the iron bridge began in August last year, with RVNL opting for a durable structure instead of the lighter Bailey bridge initially suggested. The project aims to provide a long-term solution for traffic bottlenecks. The deck slab casting will soon commence, followed by the application of a bituminous coat to complete the surface.
By the year's end, the upgraded stretch is expected to significantly improve traffic flow and facilitate smoother movement, supporting the city's growing infrastructure demands. This project reflects a thoughtful integration of Metro development with road expansion to address urban mobility challenges.
