The I-91 Brattleboro Bridge Improvements Project located in Brattleboro, Vermont includes the replacement of four bridges with two new bridges (Bridges 8 & 9). This Design/Build project is being designed by FIGG Bridge Engineers, Inc. and built by PCL Civil Constructors, Inc. for the Vermont Agency of Transportation (VTrans).

Bridge 8 will carry the northbound and southbound lanes of I-91 over Upper Dummerston Road using NEXT Beams. Bridge 9 will be a new 3-span, 1,036-foot arching concrete bridge over the West River built utilizing balanced cantilever construction. Standing 100 feet above the scenic valley, the 515-foot main span forms an open gateway anchored by curving, cathedral piers. This postcard worthy bridge will feature viewing platforms for pedestrians, hikers and visitors at the base of each pier overlooking the West River and mountainous valley. True to its theme “A Bridge to Nature,” every detail of the uniquely-shaped superstructure, piers, viewing platforms, and the railings will be complementary of the natural landscape. The piers will feature Vermont inspired, stone-formed concrete that blends with the local environment. A Visual Quality Advisory Team consisting of VTrans, local Aesthetic Committee members and FIGG will select eco-friendly concrete stain colors, platform railing designs, and other aesthetic details.

The concrete cantilever construction process offers minimum impact when crossing busy Vermont Route 30, the West River, and popular West River Trail. Construction of the $60 million project began in the fall of 2013. Bridge completion is anticipated in Spring 2017 and project completion is anticipated in Fall 2017.
