A new cable-stayed road over bridge (ROB) is under construction near Howrah Station, set to replace the nearly century-old Chandmari Bridge. Designed with an orthotropic steel deck, the 607-meter, four-lane bridge will ease congestion and enhance traffic flow, accommodating more railway tracks while also providing better road connectivity. Expected to be completed by December 2025, the project is being carried out by SP Singla Construction Pvt Ltd, with design by Taiwanese firm Weicon, at a cost of Rs 174 crore.
The new bridge will improve clearance under the span, increasing it to 134 meters, which will enable the addition of more tracks at the Eastern Railway yard, relieving the current bottleneck at Howrah Station. The existing Chandmari Bridge, constructed in 1933, has limited clearance, contributing to delays, especially during peak hours when trains bound for Howrah Station have to wait for local commuter trains to pass.
This new bridge will feature a steel plate deck, held in place by 56,000 bolts—unlike the nearby Howrah Bridge, which has no bolts. With 30,000 cubic meters of concrete, 2,000 tonnes of structural steel, and 4,000 tonnes of reinforced steel, the construction is a significant feat, with 54 cables securing the deck from an 81.4-meter-high pylon. Once completed, the new bridge will ease traffic flow, supporting two-way movement on BT Road and linking to HM Basu Road.
