SR 53 @ SR 183

complete

The proposed project would reconstruct the existing, at-grade intersection of SR 53 at SR 183 in Dawson County, Georgia, to a three-legged one-lane roundabout.  The total project length is estimated to be 0.56 mile.  The typical section for the approaches consists of 12-ft to 20-ft wide lanes with a raised splitter island, 10-ft rural shoulder beyond the inscribed circle, and 12-ft urban shoulder within the inscribed circle which includes curb and gutter and 5-ft sidewalk.  The proposed design speed remains 55 mph for all approaches.  Entry speeds at the entrances of the roundabout are kept at a maximum of 26 mph (per Fastest Paths and Entry Speeds as shown in the Roundabout Feasibility Study) with the usage of 90-ft entry radii.
