U.S. Route 191 Indian Canyon Corridor

Utah Department of Transportation (UDOT) completed multiple projects on the U.S. Route 191 Indian Canyon Corridor between US-40 and US-6 during 2023 and 2024. Improvements to the corridor will continue during the next two years to ensure the road withstands the projected additional heavy vehicle traffic and to improve safety for all travelers on the route. The 45-mile corridor runs from Duchesne to Helper.

Nearly $104 million has been allocated for improvements to the corridor. The Utah Legislature appropriated $88.5 million in their 2023 session, and UDOT has provided just over $15.49 million in additional state and federal funding for improvements to the US-191 Indian Canyon corridor.

The North of Summit and South of Summit projects are expected to begin construction in 2025 and likely extend through 2026. Stakeholder and community input guided the planned improvements, which include:

• South of Summit
  • Approximately nine miles of roadway and shoulder widening, chain-up area widening, and new pavement
• North of Summit
  • Approximately three miles of chain-up area widening and an additional southbound passing lane
  • Intersection widening at four locations
• Corridor wide
  • Installing Intelligent Transportation System (ITS) conduit, fiber optic backbone, and ITS equipment at multiple locations
  • Miscellaneous drainage and guardrail improvements

Additionally, installing a new traffic signal at the intersection of US-40 (Main Street) and US-191 (100 West) in Duchesne is planned for summer 2025.

During the 2024 construction season, three projects were completed:

• A southbound passing lane on US-191 between milepost 280 to 282
• A pavement preservation project that will place fresh pavement, update existing guardrails, and install four cattleguards at multiple locations on US-191 from US-6 to US-40
• Improvements to the intersection of US-191 and US-6
