Middlebury RS 0174(8) - Bridge 13 - VT 125 over Middlebury River (Sand Hill Bridge) Bridge Replacement Project
The existing concrete arch bridge spans 42’. The bridge was built in 1924 and has a curb-to-curb width of 24’6”. This narrow width does not allow for sidewalks, which creates an unsafe condition for pedestrians.
The design of the new bridge increases the curb-to-curb width of the bridge from 24’ 6” to 36’ to accommodate wider travel lanes, shoulders and sidewalk. The new structure will feature a five foot sidewalk to allow for easier access to both sides of the gorge and a steel/concrete combination bridge rail. The offset from the existing fascia to the new outer edge is 3’ downstream and 10’ upstream.
The final design addressed public comments concerning impacts. The VT 125 roadway alignment will be shifted approximately 6’ to the east to avoid impacts to recreational resources and archaeologically sensitive areas and to reduce impacts to adjacent properties, trees and vegetation. This revised alignment also results in improved drainage, reduced construction time and construction costs.
The bridge will be replaced using Accelerated Bridge Construction (ABC) methods. Weather permitting, VTrans will secure the work zone by closing a portion of VT Route 125 within the work area and establish the detour route. Then the contractor will demolish the existing structure and the new bridge will be constructed. The anticipated duration of the detour route will be 45 days beginning sometime between the middle of April to the beginning of May.
The bridge is located 1.5 miles east of the intersection of RT 7 and 125 over the Middlebury River.
