Phase 1 Archaeological Survey for Dug Gap Mountain Road Roundabout, Whitfield County, Georgia

Whitfield County proposes to construct a five-leg two lane roundabout to combine SR 52, College Drive and the 1-75 southbound ramps. West Bridge Road will be relocated approximately 90 feet west of the existing location to provide greater separation between the proposed intersections. The termini of SR 52 are approximately 475 feet to the west of West Bridge Road and at 250 feet to the east of the 1-75 southbound ramp intersection. The terminus of College Drive is approximately 675 feet to the north of the intersection of SR 52. The terminus of West Bridge Road is approximately 375 feet the south of the intersection of SR 52. The terminus of the 1-75 southbound off-ramp reconstruction is approximately 845 feet north of the SR 52 intersection and the terminus of the 1-75 southbound on-ramp reconstruction is approximately 815 feet south of the SR 52 intersection. The roundabout will be elevated approximately 3.5 feet higher than the existing intersection at SR 52 and the 1-75 southbound ramps to improve the vertical profile on SR 52 and the 1-75 southbound ramps. Temporary detours will be utilized along the 1-75 southbound ramps to allow for phased construction of the roundabout and approach roadways. The project will also include the construction of a stormwater pond. The roundabout will consist of a two-lane facility with two fifteen-foot travel lanes and curb and gutter. Additional right-of-way (ROW) will be required between College Drive and the 1-75 southbound offramp for the construction of the slip ramp onto College Drive and for the realignment of West Bridge Road. The project length is approximately 0.313 miles north to south and 0.173 miles east to west. The total project area is approximately 10 acres in size.
