Rainbow-coloured flyover 'fixed' overnight after video shows bikers slipping in Kolkata. After a purported dashcam video showed bikers slipping on Kolkata's Chingrighata flyover, which was painted in rainbow colours, changes were made to the flyover overnight. Cat's-eye reflectors at 10-metre intervals were installed. Meanwhile, on another flyover, the paint was "slightly scraped". Bengal minister Agnimitra Paul said public funds were not used for the "beautification process".
