Addendum to the Phase 1 Archaeological Survey of SR 135 Douglas Bypass Widening, Coffee County, Georgia

The proposed project would consist of the widening of the SR 135 bypass corridor from a twolane roadway (one travel lane in each direction) to a four-lane roadway (two travel lanes in each direction) on the south side of Douglas, Coffee County. The project would begin at SR 31/US 221/US 441 and continue northeast to SR 32. The length of the proposed project would be approximately 2.5 miles. Existing right-of-way (ROW) is approximately 160 feet to 200 feet. Proposed ROW would be 200 feet to 250 feet wide. Signaled and Stop-sign controlled intersections along the corridor would be improved, and a bridge would be constructed to provide a grade separation at the railroad crossing. This railroad grade separation would require the elimination of direct access from the side streets to SR 135 for approximately one-quarter mile (0.25) mile on either side of the railroad. Revised Project Description: The proposed project would consist of the widening of the SR 135 bypass corridor from a twolane roadway (one travel lane in each direction) to a four-lane roadway (two travel lanes in each direction) on the south side of Douglas, Coffee County. The project would still begin at the intersection of SR 31/US 221/US 441 and continue northeast to SR 32. The length of the proposed project would remain approximately 2.5 miles. Existing ROW is approximately 160 feet to 200 feet. Proposed ROW with easements would be 150 feet to 351 feet wide. Signalized and stop sign controlled intersections along the corridor would still be improved. The at-grade railroad crossing would still be removed and a bridge would be constructed to provide a grade separation at the railroad crossing. The original project description did not contain specifics related to median width and shoulder types; however, those are now known and were incorporated into the additional field reconnaissance. Changes to the proposed project include the use of 12-foot urban shoulders on SR 135 from SR 31/US 441 to McDonald/Old Axson Road and using a rural typical section on SR 135 from McDonald/Old Axson Road to SR 32/Westgreen Road. The use of a 14-foot flush median from McDonald/Old Axson Road to SR 32/Westgreen Road, and using an eight-foot raised median across the proposed bridge over the CSX Railroad. Finally, a 12-foot urban shoulder without a sidewalk on SR 158/Baker Highway west of SR 135 is included in the proposed changes. Another change to the proposed project concerns the realigning of Old Bell Lake Road. This new alignment is close to the existing alignment, with a 70-degree skew angle. Finally, the project involves changes to the existing intersection of Waldroup Road with Wood Valley Road and SR 135. These changes are shown in the included figure and involve removal of this currently unsafe intersection with the addition of a cul-de-sac at the existing intersection of Waldroup Avenue and Wood Valley Road, immediately adjacent to the existing intersection of Waldroup Avenue to SR 135. Access from Waldroup Avenue to SR 135 will be maintained via an existing unnamed graded gravel road, which would become paved roadway with two 11foot travel lanes with rural shoulders. These improvements to the existing gravel road would take place within 80 feet of proposed ROW and 16 feet of proposed easement beyond the proposed ROW.
