Bridge Projects

This project consisted of the replacement of an existing three-span, historic steel truss bridge. Which was necessitated because the existing structure did not have sufficient width (functionally obsolete) or strength (structurally deficient) to convey current standard truck loadings. The new bridge is 144 meters long and consists of a haunched, cast-in-place prestressed concrete box girder superstructure supported on single-column bents and 2.4 meter diameter cast-in-drilled-hole (CIDH) piles.

As part of the project, the deck of the existing truss bridge was replaced, the railing was modified, and the piers repaired to allow the bridge to be converted to bicycle and pedestrian usage. Quincy Engineering Inc. provided project management and prepared the final construction documents (PS&E) for the project. During construction of the bridge, Quincy Engineering Inc.. also performed construction management for the bridge.
