The Beech Street bridge replacement has begun in Lewiston. This is a project for the City of Lewiston to replace the aging single lane bridge that accesses the Lewiston-Auburn park, location of big events such as the balloon festival and Dempsey Challenge. Work began following the cleanup from this year’s Dempsey Challenge and is expected to be complete by end of year, with the exception of final paving and seeding.
The bridge itself is small, only 52’ x 30’, but the project has considerable complications due to congested underground and overhead utilities and 20’ deep abutment foundations. The project includes replacing an active water line, active storm drain line, installing 2 storm drain manholes, and protecting an active natural gas pipeline and sewer line that are within 3’ of our excavation. Once the foundations are complete we will set a pre-assembled pony truss bridge frame in place and then form and place the deck.
