Most bridge maintenance is of a specialized nature. At times cleaning, freezing, and painting bridge seats and rollers may be required. Deck joints may extrude or become filled with dirt so that their cleaning and resealing is necessary. On occasion vehicles out of control strike handrails or other appurtenances; and these must be repaired and straightened. If bridge decks become rough, resurfacing is in order. Remedial measures are sometimes required to correct serious scour around and under piers and abutments. It is common practice among highway agencies to have traveling crews exclusively for bridge work.
