Rehabilitation of Historic Willimansett Bridge

Chicopee and Holyoke, MA

Built in 1891, the historic Willimansett Bridge carries Route 116 over the Connecticut River and the Pioneer Valley Railroad. The bridge provides a vital link between the cities of Chicopee and Holyoke, Massachusetts and is a key driver for commerce in the area. Benesch provided complex bridge design for a full rehabilitation of the historic 793 foot-long structure, consisting of four 170-foot long through truss spans and two 51-foot long through girder spans for the Massachusetts Department of Transportation.

Project components included: In-depth bridge inspection utilizing special bridge rigging; rehabilitation of truss spans, including an Exodermic Bridge Deck System and metal grid sidewalk replacement; stringer, floorbeam and truss repairs and strengthening; complete replacement of through girder spans with a 2-span continuous steel through girder superstructure; seismic analysis and retrofit based on a site specific seismic assessment; temporary bridges for pedestrian use during construction; temporary post tensioning was used to allow for a complete replacement of the bottom chords.
