I-91 Bridge Improvements, Brattleboro

Project Overview

This design-build project includes removing two existing steel truss bridges over the West River in Brattleboro, Vermont, and replacing them with a single segmental bridge. The new bridge will have a minimum design life of 100 years. With a 515-foot main span and 263-foot and 258-foot back spans, the total bridge length is 1,036 feet. The bridge will be built on 66-inch diameter drilled shaft foundations with aesthetic piers, replicating Vermont’s iconic stone look. This new signature bridge will be constructed using balanced cantilever, an accelerated bridge construction (ABC) approach, to eliminate shoring that will reduce overall construction time as well as the environmental impacts on the pristine natural areas below the bridge.

PCL's approach is based on the theme of “Vermont: A Bridge to Nature” to develop an iconic, gateway structure that provides an aesthetically pleasing, high-quality, environmentally sensitive, and sustainable bridge.
