Second Addendum to the Phase I Archaeological Survey for the Proposed Bridge Replacement Carrying US 411/SR 61 over the CSX Bridge, Murray County, Georgia

This proposed project consists of the replacement of the existing US Highway (US) 411/State Route (SR) 61 bridge (Structure ID 213-0021 -0) over County Road (CR) 182 and the CSX Railroad (formerly L&N Railroad) in Tennga, Murray County, Georgia (Figure 1). This bridge was built in 1962. The overall condition of the bridge would be classified as poor to good. The deck is in poor condition due to advanced concrete cracking and spalling. The superstructure is in good condition with some minor problems. The substructure is in poor condition due to concrete cracking and spalling. Due to the poor condition of the bridge deck and the substructure, replacement of the bridge is recommended. The proposed replacement bridge would be offset from the existing bridge by approximately 115 feet to the northeast on the north end and approximately 65 feet to the northeast on the south end. The bridge would be approximately 320 feet in length. Construction of the permanent offset bridge would require the realignment of US 411/SR 61 in order to tie into the new bridge location. The proposed realignment would begin near the intersection of US 411/SR 61 at Booger Branch Road and would reconnect to existing US 41 1/SR 61 near the intersection with Pine Street. Booger Branch Road would be permanently closed at its northern intersection with US 4 11 /SR 61 as a result of project implementation, and the existing intersection of Tennga Gregory Road with US 411 /SR 61 would be slightly realigned in order accommodate the realigned section of US 41 1/SR 61. Existing right-of-way (ROW) along US 41 1/SR 61 is 60 feet. The proposed ROW along US 41 1/SR 61 varies between 60 feet and 240 feet.

                The addendum area of potential effect (APE) for the project consists of all existing and proposed ROW and easements within the current project limits, including the three remnant parcels described above (Figure 2a-b). An ESC was not included as part of this second addendum survey because the plans are in the latter stages of development and have gone through Final Field Plan Review (FFPR) and are therefore unlikely to change. Further, activities associated with remnant parcel acquisition are confined to the parcel boundaries. The northern part of the APE and the remnant parcels investigated for this addendum report are hereinafter referred to as the addendum survey area.
