BARRE TOWN BRIDGE 21
REPLACEMENT OF BRIDGE NO. 21 ON VT110 IN BARRE TOWN, OVER JAIL BROOK.
Project Location: Town of Barre in Washington County on VT Route 110 over Jail Brook. The bridge is located approximately 0.1 miles south of the junction with US Route 302.
The Barre Town Bridge 21 project includes a full bridge repalcement with traffic maintained on an offsite detour during construction. The existing structure is a 44-foot long single span Concrete T-Beam Bridge. The structure currently has a deck rating of 5 (fair), a superstructure rating of 5 (fair), and a substructure rating of 6 (satisfactory). This bridge was constructed in 1930, and widened in 1959.
VTrans evaluated alternatives for rehabilitation or replacement of the bridge in an engineering study completed in December, 2019. This study assessed the proposed design criteria for the structure, right-of-way, utilities, hydraulics, and community considerations. Several alternatives were considered, including: no action, minor rehabilitation, superstructure repalcement, and full bridge replacement on-alignment. The scoping report evaluated an offsite detour, phased construction, or a temporary bridge for maintenance of traffic.
Given the age of the structure, site constraints, exsiting geometery, needs of the Town, and current conditions, the engineering study recommended a full bridge replacement with traffic maintained on an offsite detour for 60 days. The new bridge will match the existing typical section to match the cooridor and meet minimum standards for width as set forth in the Vermont State Standards. This will include 8-foot wide shoulders and 12-foot wide travel lanes with a sidewalk on the southside of the bridge.
It is anticipated that the bridge will be constructed during the summer of 2023.
Traffic will be maintained on an offsite detour for 60 days.
