I-91 Bridge Replacement in Brattleboro, Vermont - Cantilever Construction Begins


The Vermont Agency of Transportation’s largest bridge project to date, the I-91 Bridge Replacement Project in Brattleboro, is a design-build concrete segmental bridge. This new, $60 million, four-lane bridge is a gateway to Vermont and the bridge was selected through a best value determination and awarded to the PCL/FIGG team.

This scenic bridge will be 1,036 feet long, made of segmental concrete arching shapes reaching 100 feet above the river valley. Its 515-foot main span forms a gateway with curved multi-column piers that pay tribute to the local stone. Segmental cantilever construction is used to maintain mobility on Vermont Route 30, the West River, and popular West River Trail.

PCL Civil Constructors, Inc. has completed Pier 1, is working on the Pier Table at Pier 1, and is constructing Pier 2. Work is on-schedule and PCL anticipates the superstructure will be complete by the end of 2015. The bridge is scheduled for completion in Spring 2016.
