Project Location: Town of Plymouth in Windsor County on VT Route 100A over Pinney Hollow Brook. The bridge is located approximately 2.3 miles east of VT Route 100.

The Plymouth Bridge 7 project involves replacement of the existing single span concrete slab structure. The existing bridge was built in 1947, and reconstructed in 1975. It has a length of 22 feet. The structure currently has a deck rating of 6 (satisfactory), superstructure  rating of 6, and substructure rating of 5 (fair). Deck shows moderate cracking with saturation and efflorescence. There is heavy spalling along abutment 1. Abutment 1 footing also has exposed and thinning rebar. Both abutments show cracking with rust staining and efflorescence throughout.

Given the age of the structure, site constraints and current conditions, the project will be a full bridge replacement with traffic maintained on an offsite detour. The proposed typical section will include two 11-foot travel lanes with 3-foot shoulders, for a total width of 28-feet. The new bridge will be a prestressed concrete solid slab spanning 43-feet.
