SUPPLEMENTARY INFORMATION:

Notice is hereby given that FHWA has taken final agency actions by issuing a FONSI for the following highway project in the State of Tennessee: widening and realignment of SR 66, from SR-34 (US-11E, Andrew Johnson Highway) in Bulls Gap to near Speedwell Road/Old Highway 66, in Hawkins County, Tennessee, PIN 107579.00. The project extends approximately 5.70 miles and includes widening the existing two-lane roadway to provide two 12-foot travel lanes with paved shoulders. The Build Alternative would generally follow the existing SR-66 alignment, with minor horizontal or vertical shifts in select locations to address existing geometric deficiencies. Project improvements also include an intermittent 12-foot two-way left-turn lane, sidewalks, curb and gutter, and guardrail installed at various locations along the corridor.

The FHWA's actions, related actions by other Federal agencies, and the laws under which such actions were taken are described in the Environmental Assessment (EA) for the project, approved on April 15, 2025, and the FONSI approved on October 17, 2025, and other documents in the project file. The EA and FONSI are available by contacting FHWA or TDOT at the addresses provided above.
