Kentucky Highway 80 Extension

Calloway County, Kentucky


The Kentucky Transportation Cabinet proposes to extend Kentucky State Route 80 (Ky. 80) 2.6 miles from Station 500+000 to Station 513+853 on a new right-of-way from existing U.S. 641 north of Murray to Ky. 1836 north of Coldwater. The new route would be an extension of existing Ky. 80 and would be constructed across numerous streams and tributaries northwest of Murray, in Calloway County.

The state-funded construction project would require the filling of nine separate wetland areas and the crossing of 42 individual stream channels with 36 culverts and several minor associated alignment relocations. The roadway would provide alternative access to county roads in the area, improve commerce, and benefit the local economy and community.

Since the placement of culverts in streams and bridges over streams involves construction of permanent obstructions to tributaries of the Tennessee River and their floodplains, approval would be required from the Tennessee Valley Authority under Section 26a of the TVA Act. Section 26a permits would be issued for four bridges, 36 culvert installations, and six stream relocations.

Because the extension of Ky. 80 also requires approval from the U.S. Army Corps of Engineers, the agencies decided to cooperatively prepare an environmental assessment (EA) on the impacts of the proposal. TVA independently finds that the effects of the project, with mitigation, would be minor and insignificant and has prepared the referenced finding of no significant impact (FONSI) adopting the EA as its own. The TVA FONSI can be viewed below.
