The cancerous corrosion of reinforcing steel in highway bridge decks exposed to salt-laden air or deicing salts leads to ongoing problems of maintenance, repair, and even deck replacement. But recent Canadian research and ensuing code developments now point the way to a cure: Build concrete bridge-deck slabs free of internal steel reinforcement. The satisfactory performance of the steel-free deck slabs of five Canadian bridges under unrestricted traffic solidly supports the validity of the concept.
