Fundamentals of Bridge Maintenance and Inspection by New York State department of transportation

Bridges, including those on local roads, are integral elements of our highway systems. Despite their importance, however, they are often the most neglected components of the infrastructure. Demands on limited resources, especially competing roadway priorities for increased capacity and improved riding surfaces, too often result in deferred maintenance for bridges. The consequences are obvious — bridges are deteriorating far faster than they are being repaired. Without adequate attention, many require replacement or closure long before they are really obsolete, further adding to the demand for limited funds, impacting safety, and discouraging both users and transportation providers.
