Addendum to the Phase I Archaeological Survey of the Proposed Improvements to the Glade Road Title: Project Area, Bartow County, Georgia

The selected alternative for P.I. Number 0003770 would widen and reconstruct Glade Road (CR 633) in Bartow County from Homestead Drive (CR 605)/Apache Drive (CR 377) to Ryan R (CR 810)/Yacht Club Road (CR 386). These limits would include a distance of approximately 3.7 miles. The first phase of the construction, P.I. Number 0008960, would improve the intersection of Glade Road with Catfish Court (CR 705), Buckhorn Trail (CR 706), and Sugar Hill Road (CR 389). The project limits for the first phase, P.I. Number 0008960, would extend from approximately 510 feet south of Catfish Court to approximately 50 feet north of Sugar Hill Road, for a length of 0.227 mile. The existing roadway consists of two 12-foot travel lanes (one in each direction) on approximately 60 feet of right-of-way. The proposed project would improve the roadway to meet 35 mph American Association of State Highway and Transportation Officials (AASHTO) design speed. This would require horizontal and vertical realignment in several areas in order to meet the speed design. A rural two-lane section would be used throughout the project limits. The proposed typical section would consist of two 12-foot travel lanes (one in each direction) with eight-foot rural shoulders (two feet paved) on right-of-way varying from 80 feet to 180 feet in width. Sidewalks and bicycle lanes were considered but would not be practical because the improvements on Glade Road would be constructed in sections based on safety priority. These sections would not be contiguous, and there would be gaps between the areas with bicycle lanes and sidewalks. However, the eight-foot wide shoulders with two-feet of pavement would provide more area for pedestrians to move out of the roadway. Existing intersections at connecting streets would be upgraded as necessary to better accommodate access to and from these side streets. These improvements on the side streets would be limited to adjustments to grade and skew in order to provide for adequate stopping and intersection sight distances. Capacity analyses of the intersections indicate that the addition of turn lanes would not be required to provide adequate operational level of service. The project limits along the cross streets would vary up to a maximum distance of approximately 250 feet from Glade Road.

The proposed project would include the replacement of the existing 263-foot long by 27-foot wide Glade Road Bridge over Allatoona Lake. The proposed bridge would be permanently realigned approximately 90 feet east of the existing bridge location. The proposed bridge would be approximately 600 feet long and 44 feet wide to accommodate two 12-foot travel lanes with 10-foot shoulders.
