Swayback Bridge Restoration

A large ice jam broke and sent significant ice and debris over the historic Swayback Bridge, which caused significant damage to the stonework. Bolton & Menk mobilized to perform an emergency assessment of the structural condition, including recommendations for temporary provisions to quickly reopen the structure to the traveling public.

Bolton & Menk prepared restoration plans and specifications, including reconstructing damaged portions of the stone parapets and fascia, pier repairs, mortar replacement, historic tuckpointing repair, and expansion joint reconstruction. Although locally funded at the time of construction, all restoration design was specified to be performed in accordance with the Secretary of Interior’s Standards for Historic Preservation—preserving the historic elements of the bridge and maintaining eligibility for future federal funds.
