The proposed project would construct a grade-separated interchange at the existing at-grade intersection of SR 316 and SR 53 in Barrow County. The proposed grade separation would include provision of full interchange providing access to and from SR 316 and SR 53. The interchange would be designed to accommodate the future widening of SR 316 from existing two general-use lanes in each direction to three lanes including a barrier separated high occupancy vehicle (HOV) lane in each direction. SR 316 currently provides four 12-foot travel lanes (two in each direction) separated by a 44 - foot grassed median. The existing right-of-way is approximately 300 feet wide. The roadway has 10-foot right shoulder and six-foot left shoulder with rural drainage. SR 53 currently provides two 12-foot travel lanes with two-foot shoulders and rural drainage. The existing right-of-way is approximately 80 feet wide. The existing intersection with SR 316 is signalized. Project CSNHS-0008-00(43 1) would construct a full diamond interchange at the existing atgrade signalized intersection of SR 316 and SR 53. Proposed ramp heads will be spaced 500 feet apart. Improvements to SR 53 would begin approximately 0.18 miles southeast of the existing SR 316/SR 53 intersection and continue northward along SR 53 for a total length of approximately 0.36 mile. The proposed SR 53 would tie in to the existing typical section at project terminals. The SR 53 bridge over SR 316 would provide a total of four lanes, one through lane plus one left turn lane in each direction. The proposed right-of-way width would be 100 feet wide.
