Edgewood Avenue Bridge Replacement
The project sought to replace the structurally and hydraulically deficient steel multi girder bridge with one that improves pedestrian mobility, is more hydraulically efficient, and is both aesthetically pleasing and low maintenance. The existing bridge was replaced with a precast concrete frame structure. The precast concrete frame eliminated the existing steel deck grate, steel girders and concrete abutments, which created a low maintenance structure. The precast concrete frame structure, spanning 28 feet, was constructed on a new concrete foundation on sound bedrock. A stone facing on the structure headwalls and wingwalls enhanced the aesthetic of the structure. The stone facing is similar to the private bridges upstream and the Evans Road crossing of Allen Creek.
The vertical profile was raised by about 6 inches at the bridge location to provide a vertical curve at the bridge and increase the freeboard. The bridge structure was widened to accommodate wider shoulders and a sidewalk on the east side of the bridge. The roadway reconstruction was limited to transitioning the bridge profile and width to meet the profile and width of the existing highway. An asphalt pavement section was used above the structure with bridge railing.
