Work is underway on this $12.6 million project to replace two high-traffic bridges in downtown Gardiner and add a new pedestrian bridge over Cobbosseecontee Stream. The Maine Avenue bridge is a contractor option detail-build, which will be comprised of 78-foot long concrete Next Beams, founded on precast concrete abutments and H-piles. Reed & Reed will be allowed a 15-day closure to shut the road down, detour traffic around the site, and demolish and construct the new bridge.
The Bridge Street structure will replace a 3-span concrete bridge with a 135-foot long steel stringer bridge with a conventional concrete deck, rail and curb. Reed & Reed will build this bridge on temporary supports next to the existing bridge and then slide it into place. We have 30 days to shut down and demolish the existing bridge and slide the new bridge into place and put traffic back on it. This new bridge will sit on micro-piles and precast abutments, which are to be built under the existing bridge before we begin the 30-day closure.
Our earthwork subcontractor Steven McGee is locally based and plays a key role in coordinating and managing traffic flows through the congested site. As is typical for projects like these, many utilities must be relocated through the project and keeping traffic flowing smoothly is a key goal.
Work is scheduled to be complete in November, 2020.
