Hospital Road Bridge over the Nashua River

Harvard and Shirley, Massachusetts

BETA designed a new bridge to carry Hospital Road over the Nashua River between the towns of Harvard and Shirley, Massachusetts. The project included the preliminary and final design of a three-span replacement structure comprised of prestressed concrete box beams and a reinforced concrete deck. New abutments founded on drilled shafts were installed behind the existing abutments. The two new piers, supported by drilled concrete shafts, were built in the river between the existing piers.

In order to improve the roadway geometrics and provide sufficient cover over the utilities, the roadway was raised, which required the reconstruction and widening of the roadway approaches. A temporary utility bridge was constructed to the south of the existing bridge as the existing utilities needed to remain in-service during construction.
