Project Location: Town of Dorset in Bennington County on VT 30 over drainage culvert. The bridge is located approximately 7.1 miles north of the junction with VT 7A.

The Dorset Bridge 58A project involves the replacement of the existing ACCGMPC (Asphalt Coated Corrugated Galvanized Metal Plate Pipe). The existing culvert was built in 1949, and has a length of 56 feet. The structure currently has a culvert rating of 4 (poor). There are areas of freckled rust and minor rust staining throughout. The splice connections and sides of the pipe near the center have scattered small areas of heavy rust scale with deep pitting, and minor to moderate section loss. The north side has scattered large perforations as well, measuring 1’- 2’ in diameter, which has caused some loose fill to fall through. The grated drop inlet and surrounding retaining concrete blocks are undermined 6”- 1’ vertically and penetrating 3’+/-. In addition, VT Route 30 has a substandard vertical crest curve through the project area, and existing shoulder widths are substandard.
