VT ROUTE 118 - MONTGOMERY BRIDGE PROJECTS

The Vermont Agency of Transportation in conjunction with A.L. St. Onge Contractor Inc. (St. Onge) will be replacing the bridge decks on VT Route 118 in Montgomery. Bridge 19 is over the Trout River just east of Comstock Bridge Road. Bridge 20 is over West Hill Brook between West Hill Road and Hill Road West.  

This project replaces both bridge decks that were constructed in 1953 with decking that has a greater load capacity than the existing. The bridge railings will also be replaced with new crash tested railings that ties into the surrounding community and satisfies the historic requirements.

The anticipated completion is November 2022.
