Traffic bottleneck relief in sight as Kalyan station flyover completes crucial milestone: All you need to know

Authorities have completed the launching of the final girder for the longest and most crucial flyover under the Station Area Traffic Improvement Scheme near Kalyan railway station, marking an important milestone aimed at easing long-standing congestion in the busy station area.

The 1,125-metre-long flyover from Subhash Chandra Bose Chowk to Bailbazar Chowk has entered its final stage of construction. Officials said the structure, with a width ranging from 9 to 18 metres, will help improve traffic movement once completed.

The structure has been constructed using Ultra-High Performance Fibre Reinforced Concrete (UHPFRC), a Malaysian technology also used in the Mumbai-Pune Missing Link project, known for its high strength and durability.

Officials said UHPFRC offers five to six times higher compressive strength than conventional concrete and is highly resistant to weathering and pollution, giving the structure a lifespan of over 100 years.

The flyover is part of the Station Area Traffic Improvement Scheme designed to reduce heavy congestion outside Kalyan railway station and improve overall traffic flow in the area.

The flyover’s structural design and proof-checking were carried out with technical support from IIT Bombay, ensuring improved safety and durability standards.

Engineers faced a key challenge due to an existing foot overbridge at Pandit Jawaharlal Nehru Chowk. They used UHPFRC technology to complete girder launching without dismantling it or affecting pedestrian movement.

The final girder launching was carried out late at night with civic officials, engineers, consultants, and contractors present to ensure smooth execution with minimal disruption.

Officials said the other two flyovers under the SATIS project are also nearing completion. All three will be interconnected to improve traffic circulation in the station area.

The project is being executed by the Smart Kalyan Dombivli Development Corporation Ltd as part of efforts to upgrade infrastructure and reduce congestion around the railway station.
