Addendum to Phase I Archaeological Survey of SR 17/SR75 over the Hiawassee Rover

Project BRST-0000-00(301), Towns County, P.I. No. 0000301, Addendum to Phase I Archaeological Survey of SR 17/SR 75 over the Hiawassee River, would replace the structurally deficient bridge on State Route (SR) 17/SR 75 over the Hiawassee River, 6.5 miles south of Hiawassee, Georgia. The total project length would be approximately 2,650 feet (0.50 mile). The existing bridge, constructed in 1939, is approximately 104 feet long and 26.5 feet wide. SR 17/SR 75 consists of two 12-foot travel lanes, one in each direction, with rural shoulders. The existing right-of-way width is approximately 100 feet. The existing speed limit is 55 miles per hour. The proposed bridge would be constructed on new alignment approximately 50 feet, centerline to centerline, west of the existing bridge alignment. Traffic would be maintained on the existing bridge during construction of the proposed bridge. The proposed bridge would be approximately 190 feet long and 44 feet wide. The bridge would include two 12-foot travel lanes and 10-foot shoulders. The roadway approaches would consist of two 12-foot travel lanes and 10-foot shoulders, two feet of which would be paved. Additional right-of-way, up to 50 feet in width, would be required for a total right-of-way width of approximately 150 feet. Permanent easement for the construction and maintenance of slopes would be required. Permanent easement up to 30 feet wide would be required on the west side of the required right-of-way. Permanent easement varying from 0 feet to 20 feet in width would be required on the east side of the project for approximately 350 feet ending approximately 150 feet south of the northern project terminus. The proposed speed limit would remain 55 miles per hour. Driveway easements up to 85 feet in width would be required on the west side of the roadway. Driveway easements approximately 10 feet wide would be required on the east side of the roadway.
