STC-6820, S 5000 W; W 2500 S to W 1000 S reconst, teton CO

The Federal Highway Administration (FHWA) awarded the Idaho Department of Transportation $100,000 under the Highway Planning and Construction program (CFDA 20.205) on September 15, 2025, for the reconstruction of S 5000 W in Teton County, Idaho. The project involves widening the roadway from its current 20-22 feet to a county standard width of 30 feet to accommodate its classification as a major collector route. The reconstruction work is scheduled for completion by July 31, 2031, and will include modifications to vertical grades and slope improvements as evaluated during the design phase.

This formula grant represents a component of the Federal-aid Highway Program, which provides states with annual funding for highway construction, preservation, and improvement projects. Under this program, state departments of transportation, in coordination with local authorities, select projects based on established planning processes and transportation priorities. The awarded project aligns with the FHWA's support for highway reconstruction and safety improvements on public roads, with all work subject to environmental compliance requirements and FHWA oversight in accordance with stewardship and oversight agreements between the federal government and the state.
