SUNDERLAND BM20102 20B155 - Bridge 19-5

SUNDERLAND NH CULV(122) 23B027 - Bridge 19-7


The existing 162 foot long, 8-foot-wide Corrugated Galvanized Metal Plate Pipe Arch (CGMPPA) is in satisfactory condition; however, the invert is in poor condition. The invert has heavy corrosion present with large perforations throughout causing piping and voiding. The remaining structure invert has heavy pitting and rust scaling throughout. This bridge was constructed in 1978.

Given the age of the structure and current condition, the engineering study recommended a full replacement with a precast concrete box culvert.

This project proposes a short-term bridge closure period to replace the existing culvert with a new precast concrete box while maintaining traffic on an offsite detour.

Bridge closure duration and detour routes to be determined. VTrans will work with the Towns of Sunderland, Shaftsbury, Manchester, and Arlington to determine the best timing of the closure. Continuous traffic counters along US Route 7 show that traffic volumes along the corridor are the lowest in April and May and are the highest in August and October.

The bridge closure should occur when traffic is at its lowest and avoid any possible community events
that would have an impact on traffic.
