Project: Nizamuddin Bridge, Delhi

 

Details: The bridge, with an overall length of 550 meter, has 2 independent carriageways. Two 900 mm diameter MCD are supported in the bridge between the 2 carraigeways. A 3 meter wide footpath supported on cantilevered brackets has also been provided on either side.

 

Challenge: The bridge had suffered damage to concrete on account of spalling of rebars and prestressing steel, ceasing of bearings and heavy corrosion of RCC elements supporting the water mains.

 

Solution: The rehabilitation of the bridge was carried out by providing independent supports to the water mains and external cables for strengthening of the PSC girders. The structure was also lifted and bearings were cleaned and reinstated.
