Bridge Repairs and Maintenance

Bridges constantly undergo maintenance work to ensure bridges remain in sound condition. Maintenance activities include washing (to ensure debris and other materials do not contribute to the corrosion of the steel and concrete elements of the structure), cleaning and painting of structural steel, lubrication of bearings, cleaning of debris, sealing joints, and asphalt repairs contribute to the health and love of service of a bridge.

Bridge Preservation

Bridge preservation projects address minor structural issues noted during bridge inspections before problems become costly. Preservation work requires little if any design and engineering work.

Minor Bridge Rehabilitation and Betterments

Minor bridge rehabilitation and betterment projects address bridges that are generally in good condition but have limited deterioration making a bridge structurally deficient. Typically, limited rehabilitation or betterment projects repair deterioration allowing a bridge to move out of structural deficient status. Work may include deck replacement, safety upgrades, and increases to carrying capacity.

Major Bridge Rehabilitation

Major bridge rehabilitation projects address components of bridges which have deteriorated significantly. Rehabilitation involves replacement of major bridge elements such as superstructure, along with upgrades to meet modern bridge codes.

Bridge Replacement

Bridge replacement is required when deterioration of a bridge is so significant that the structure has reached the end of its service life. This is chosen when rehabilitation of individual bridge components is more costly than complete bridge replacements.
