The most noticeable and problematic concrete spalls occur on the bridge deck surfaces. When spalls occur on the driving surface of the bridge deck, investigation on the underside of the deck (soffit) at that location should occur to verify the distress is contained to the upper surface, which is usually the case. If significant cracking of the soffit of the deck corresponds with the upper surface spall, immediate action may be necessary to address the situation. The main short-term issues related to riding surface spalling are driver disruption and potential reinforcing steel failure.
