Wait for an underpass at Gaur Chowk — one of the city’s busiest crossroads — is set to get longer as the Greater Noida Authority recently re-invited a request for proposal soliciting bids for the Rs 78-crore project. The underpass expected to ease traffic movement towards Pratap Vihar, Surajpur and Greater Noida, will come up parallel to a 60-metre road and intersect a 130-metre road at the Char Murti.
