Due to the changing nature of vehicle weights, bridge load ratings need to increase to meet current design standards. In addition, concrete compresses from use over time and needs maintenance. By adding more steel rebar into the bridge support columns, bridge stability and load capacity is improved.
What Are The Benefits of This Project?
Maintains the safety of our roads: This work will maintain long-term safety by ensuring this bridge can continue serving travelers.
Improves our roads: Steel rebar in the bridge columns and reinforced concrete will increase the stability and load capacity of the bridge.
What You Can Expect To See
Work will be performed from the deck of the SW 12th Ave bridge and will be visible during the day. People using the sidewalk may have periodic stops and will see construction equipment on the bridge. Flaggers will be directing one- way traffic across the bridge. Lane closures allow time for poured concrete to cure. SW 12th Ave bridge will remain open at all times.
