Turner Center Bridge Replacement

Bridge design keeps two Maine communities going with the (traffic) flow

Turner and Greene, Maine

Between the two Maine towns of Turner and Greene lies the dam-controlled Androscoggin River—and a 90-year-old bridge that needed to be replaced. With the closest crossing 20 miles (32 kilometres) away, a detour wasn’t possible. The Maine Department of Transportation would need a new bridge and a way to maintain traffic during its construction.

As owner’s engineer, we developed the RFP and performed the independent design review. We also helped develop a conceptual bridge design, identify potential impacts for early permitting, and coordinate early public participation. Our support during construction included performing temporary works design reviews.

As the lead designer for this design-build project, Fay, Spofford and Thorndike (FST) planned the new bridge using a horizontally curved steel girder. The 480-feet-long (147-metre-long) girder, and the bridge’s vertical curve, minimized the approach work needed, reduced costs, and met flood-level-clearance requirements. The bridge ties into the existing roadway at the abutments and addresses ice flows with its singular mass pier design. Plans were done in stages and early approvals obtained to release bridge components for construction. This approach, and the fast-track design, minimized traffic disruption.

After the completion of this project, FST was acquired by Stantec. Together as a team, we continue to build strong relationships and deliver award-winning projects.
