Addendum to the Phase I Archaeological Survey of Five Proposed Bridge Replacements, Coweta County, Georgia

The original survey of five bridge replacements was conducted by New South Associates on July 8, 1996. The survey covered a 1,000 foot approach on either side of each bridge and a total 120 feet of right-of-way at the bridges. Following this survey, the alignment was changed at the Henry Bryant Road crossing of Wahoo Creek. The new project area at that bridge is described as follows.

The project would begin approximately 280 meters (918) feet northwest of Wahoo Creek and terminate approximately 100 meters (328 feet) east of Wahoo Creek. The project would replace the existing bridge with a 39.0 x 10.6 meter (128 x 35 foot) concrete bridge. The project would require approximately 16.5 meters (54 feet) of additional right-of-way, where the improvements are to be completed along the existing alignment. It is also proposed to realign a dangerous curve at the western bridge approach. This curve, along Henry Bryant Road, would be realigned beginning approximately 101 meters (331 feet) from the western end of the project. The revised alignment would then proceed on new location in an easterly direction for approximately 150 meters (492) feet, where it would connect back into the existing alignment at a point which is approximately 18 meters (59 feet) west of the proposed bridge structure. The centerline of the revised alignment is approximately 38 meters (125 feet) north of the existing at its furthest point. The total length of the project including the bridge and approach road would be approximately 380 meters (1,246 feet) (Figure 1).

This addendum report contains only a discussion of the survey of the original right-of-way, a description of the additional work performed, and conclusions regarding the findings of the additional survey.
