Defects included low concrete cover over reinforcement, substandard concrete strengths, spalling on different areas of the bridge decks and parapets, install of coating to reduce the impacts of Alkali Aggregate Reaction (AAR)
  • Communication with agricultural contractors was required so wide loads being transported were not hindering bridge works
