Bridge Maintenance Policy

The structural and operational characteristics of all highway bridge structures should be preserved as near as practical to the originally constructed or subsequently modified conditions.

Bridge joints are the causes of many bridge problems. Bridge joints should be evaluated during the routine bridge inspection and if needed, cleaned and resealed.

Such objectives are accomplished by timely performance of preventive maintenance and repair as determined by constant alertness and deliberate inspection.
