This article examines the prestressing for a concrete bridge. Prestressing enhances the capacity of a member that is weak in tension, but strong in compression. It effectively creates a new material that is strong in tension. A prestressed bridge has much less steel to be handled, which reduces congestion, leading to easier and quicker concrete placing.
