Design and Construction of Pre-Tensioned Sutlej Bridge in ...

Currently in vogue fast track construction has encouraged the adoption of pre-tension technology for urban flyovers. After having successfully experimented pretensioned spans for River Bridge upto span of 30 m in Hadakiya Bridge in Gujarat, the technology was first time extended upto 35m spans for Beas and Sutlej river bridges in Punjab.

Prestressed concrete bridges: design and construction

Prestressed concrete decks are commonly used for bridges with spans between 25m and 450m and provide economic, durable and aesthetic solutions in most situations where bridges are needed. Concrete remains the most common material for bridge construction around the world, and prestressed concrete is frequently the material of choice.
