The purpose of this project is to replace the existing Karnes Creek bridges on Route 696 (Selma-Low Moor Road) and Route 1308 (Garland Road) with a single structure on Route 696.
Replacement of the Route 1308 bridge will require relocation of part of the roadway and development of a new intersection with Route 696. The existing Route 1308 bridge will be removed.
This proposed project is located approximately 0.05-mile west of Route 616 in Alleghany County, approximately 0.3-mile southeast of Interstate 64 (Exit 21).
The Virginia Department of Transportation (VDOT) Cultural Resource Division has worked with the Virginia Department of Historic Resources to ensure the project will have no adverse affect on the potential Low Moor Historic District in the area.
The Route 696 bridge, built around 1900, is a concrete structure 65 feet long and 26 feet wide. The roadway approaches are about 19 feet wide. The two-lane bridge is posted for loads no greater than 15 tons. Its condition qualifies the structure as a candidate for federal funds for replacement.
The Route 1308 bridge was constructed in 1970 with steel beams and timber decking. The two-lane bridge is about 61 feet long and 19 feet 8 inches wide. The roadway on either side of the bridge is about 14 feet wide, with significant hills and curves.
The new bridge on Route 696 would be 65 feet long and 40 feet wide, with two 11-foot lanes and 8-foot shoulders.
The roadway approaches will more closely meet current design standards. Relocating a portion of Route 1308 to a new intersection with Route 696 will eliminate the need for the current bridge on Route 1308.
There are no special accommodations on this project for bicycles and pedestrians.
Route 696 has an average traffic count of 2,100 vehicles a day. The projected traffic volume is 3,087 vehicles a day in the year 2041. Route 1308 has an average traffic count of 31 vehicles a day, with a projected traffic volume of 46 vehicles a day in the year 2041.
The total estimated cost for the project is $4,066,731, which included $691,926 for preliminary engineering, $377,371 for right of way and $2,997,434 for construction.
This project replaces two existing substandard bridges on state-maintained roadways that serve residential areas, local business and industry.
If not replaced, the existing bridges will continue to deteriorate and would eventually have to be closed to vehicles.
