STC-2820, trail creek RD safety imprv, blaine county

The Federal Highway Administration awarded the Idaho Department of Transportation $289,544.72 on June 17, 2026, under the Highway Safety Improvement Program (CFDA 20.272) to rehabilitate and widen Trail Creek Road in Blaine County, Idaho.

The project improves safety by rehabilitating the existing base material, widening the roadbed, and resurfacing with hot mix asphalt pavement. The work includes a 2-foot paved shoulder on both sides for a total pavement width of 26 feet, assuming 11-foot travel lanes. The project begins at the one-mile marker past the northerly city limits of Sun Valley, where the existing pavement narrows and the fog line ends, and extends approximately 1.6 miles to a point just past the fatal crash location at mile post 6.1.

Performance extends through July 31, 2029, with work performed in Idaho.
