Designing Bridges for Durability
This article discusses ways in which the cost of bridge maintenance and inspection can be reduced in the future. Since the collapse of the I-35W Mississippi Bridge in Minnesota in August 2007, the funding problem in bridge maintenance has become a central issue, one that may potentially jeopardize the safety of drivers. Public officials and engineers are addressing this setback through changes in construction and materials with the intention of ensuring easier and quicker access for inspectors. Examples given include stay-cable connections at tower and deck surfaces, more stairs and elevators, the elimination of expansion joints, and the protection of the deck slab. In addition, the article notes several building materials, such as weathering steel for steel bridges and post-tensioned cable strands for cable bridges, that will endure better and save on future maintenance costs.
