GARDINER — The final phase of a comprehensive transportation improvement project in Gardiner’s historic downtown is nearing completion with the recent opening of the Bridge Street Bridge. Global design firm Stantec led project design and provided construction support for the Maine Department of Transportation project involving the replacement of two century-old bridges, along with the addition of a multi-use trail with bridge, and updates to two signalized intersections.
The Bridge Street Bridge, which was built in 1917 to bring U.S. Route 201 over Cobbosseecontee Stream, recently opened to traffic after a complex lateral slide installation of a 700-ton single span structure. Completed during a 30-day closure using Accelerated Bridge Construction methods, this was only the second such highway bridge replacement completed in the state.
The completion of the Bridge Street Bridge follows the 2019 replacement of the Maine Avenue Bridge through an accelerated 15-day bridge closure. The Maine Avenue Bridge was built in 1933 to carry Route 24 over Cobbosseecontee Stream. The bridge updates, coupled with complementary roadway and trail improvements, bring a substantial set of multi-modal mobility improvements to this historic downtown.
Full project completion is slated for spring, once trail and intersection enhancements are complete. Reed & Reed Inc. is project general contractor, with McGee Construction serving as subcontractor. Additional key design subconsultants are Haley & Aldrich for geotechnical and TMSI for signalized intersections and utility coordination.
