Kalupur Flyover is a very important two-lane bridge connecting major areas of Ahmedabad like Shahibaug, Asarwa and Kalupur. Thousands of vehicles pass through this flyover every day. Special planning was done to avoid any major inconvenience to the local people and traffic.

Permission was obtained from the Ahmedabad Traffic Department for a night traffic block from May 22 to May 25, 2026. Under this, the bridge's access roads were completely closed only from 12:00 am to 06:00 am. In this limited period of just three nights, all the technical processes like auto-launching, segment transportation, span erection, dry matching and gluing were completed. During the day, traffic continued as usual.

Adequate precautions were taken for the safety of passengers during the operation. Barricading, traffic diversion boards, advance public notices and adequate lighting at night were arranged in the entire area. In addition, traffic marshals were also deployed day and night to guide motorists.
