Addendum Phase I Archaeological Survey of East Solomon Street at Spalding Street/Searcy Avenue in Spalding County, Georgia

The proposed project consists of intersection reconfigurations in downtown Griffin in Spalding County, Georgia (Figure 1). The project would reconfigure the five-legged intersection at the Norfolk Southern Railroad, East Solomon Street, Searcy Avenue, North Searcy Avenue, and Spalding Street intersection just east of downtown Griffin. The segment of East Solomon Street located east of the Norfolk Southern Railroad would be realigned to the north and would directly connect to the segment of East Solomon Street located to the west of the railroad with an at-grade crossing with crossing gates over the Norfolk Southern Railroad.

The current typical section in the area consists of two-lane roadways with 3.4 to 3.7-meter (m) (11 to 12-foot [ft]) lanes and the speed limits are 56 kilometers-per-hour (kph) (35 miles-per-hour[mph]). The typical section of the proposed realignment of East Solomon Street would contain two 3.4 to 3.7 m (11 to 12 ft) lanes and curb and gutter with a middle left turn lane to access Searcy Avenue from the westbound approach and a right hand turn lane to access Searcy Avenue from the eastbound approach. The existing right-of-way (ROW) is approximately 10.9 m to 27.4 m (36 to 90 ft) wide along East Solomon Street. Searcy Avenue lies within the existing 30.5 m (100 ft) railroad ROW. The proposed ROW and easements are anticipated along both East Solomon Street and Searcy Avenue. Amounts will be determined later.

Spalding Street connects to the current intersection from the southeast. Spalding Street would have a cul-desac installed as it approaches the railroad, and the one-way North Searcy Avenue (located north of East Solomon Street) would end at a commercial driveway north of the reconfigured intersection. Both roadways would no longer connect to the existing five-legged intersection. The existing ROW is approximately 13.7 m (45 ft) wide along Spalding Street and ties into the existing railroad ROW. The existing ROW is approximately 5.5 m (18 ft) wide along North Searcy Avenue and ties into the existing railroad ROW. No proposed ROW is anticipated along Spalding Street. Proposed ROW and easements are anticipated along North Searcy Avenue. Amounts will be determined later.

In addition to the reconfiguration of the five-legged intersection, a four-legged single-lane roundabout would be installed to the east at the current intersection of East Solomon Street and Jackson Lane. The existing ROW along Jackson Lane is approximately 10.7 m to 23.8 m (35 to 78 ft) wide. Proposed ROW and easements are anticipated, and amounts will be determined later. A new two-lane roadway would be constructed to form the south leg of the roundabout and would connect Spalding Street to East Solomon Street. Proposed ROW is anticipated along the new south leg of the roundabout, and amounts will be determined later.

Sidewalk facilities would be installed at the roundabout approaches, the roundabout itself, and the new location roadway, as well as along the realigned East Solomon Street. Displacements would occur as a result of the proposed improvements. The proposed project length would be approximately 0.37 kilometer (km) (0.23 mile [mi]).
