Project: 7 Bridges between Surat - Vadodara, Gujarat

 

Details: The bridges were more than 100 years old, and were located along a stretch of 109 km. The existing bridges were steel girder bridges having 3 600 mm (phi) cast iron piles covered with stone masonry piers.

 

Challenge: The cast iron piles were corroded significantly and needed to be replaced.

 

Solution: New pile foundations were laid between the 2 old foundations and RCC piers. The plate girder decking was replaced by prestressed concrete girders. A notable achievement was that the entire project was executed without disrupting traffic.
