MUMBAI: A 320mt bridge over the Pa River in Valsad (Gujarat) of the Mumbai-Ahmedabad High Speed Rail Corridor (MAHSRC) will be ready within a week. This will be the first river bridge in the bullet train corridor.
An official said the bridge will have eight full-span girders, each 40m long, with only four columns remaining to be completed. The height of the piers on which these girders are placed ranges from 14.9 to 20.9 m.
“Putting piers on a river is complicated. This includes complex geotechnical investigations. First you have to lay the foundation for the well. Then the piers from which the girders begin will be laid. The track will finally come up on the girder,” he said.
“The proposed bullet train will cross several rivers: Narmada, Sabarmati, Mahi, Par, Kaveri, Purna Ambika, Daroatha, Daman Ganga, Tapi, Kim, Vishwamitri, Mohar, Vatrak and Meshwa. Nearly 20 bridges will be built,” the official said, adding that the longest would be the 1.2 km bridge across Narmada in Bharuch and around 720m between Tapi and Mahi.
Currently, the Mumbai-Ahmedabad high-speed rail is the only approved project in the country. At 320 km/h it crosses the western landscape in just 2 hours and 15 minutes covering 508.17 km between Mumbai and Ahmedabad.
