The Utah Department of Transportation is moving forward with massive infrastructure investments in Utah County, including a nearly $1.4 billion allocation for new projects, building upon foundational planning efforts initiated in early August 2026. These developments, which include significant freeway expansions and expressway construction, aim to address growing regional congestion and improve connectivity across the state's highway and transit systems.
Mountain View Corridor Expansion
The Mountain View Corridor South project has reached a critical milestone following the completion of its Final State Environmental Study in December 2025. This study determined that the proposed southern extension meets the transportation needs of southern Saratoga Springs while minimizing environmental impacts. The project consists of a 10.7-mile southern extension of the Mountain View Corridor, featuring a freeway-frontage road from Cory B. Wride Memorial Highway (SR-73) to Lariat Boulevard and an expressway stretching from Lariat Boulevard to Redwood Road. Additionally, the plan includes two 12-foot-wide shared-use trails running parallel to the frontage roads and expressway, with designated crossings over and under local streets.
Future Project Timelines
As the Mountain View Corridor South moves toward future construction, the project enters a phase where it is eligible for funding for subsequent stages, including right-of-way acquisition and final design. According to the Utah Department of Transportation, the first phase of funding for the Northwest Utah County Program is anticipated to arrive in 2031. This project follows the foundational planning processes established in the Statewide Transportation Improvement Program (STIP), which serves as the official work plan for UDOT to develop projects through conception, environmental studies, and construction advertising.
Lehi Freeway Improvements
In Lehi, the 2100 North Freeway Project is currently under development to improve east-west travel times across northwest Utah County. This 2.8-mile freeway segment, located on SR-194 between the Mountain View Corridor and I-15, is designed to provide a freeway-to-freeway connection that could save commuters approximately 12 minutes in each direction during peak periods. Construction on the project was slated to begin in the spring of 2026, with preliminary completion estimates set for late 2028.
Project Preparation and Public Input
The 2100 North project has undergone several stages of preparation, including an environmental re-evaluation in the spring of 2025 and right-of-way acquisition efforts throughout late 2025. The Utah Department of Transportation has maintained public engagement throughout this process, providing information via specialized public input channels to keep residents informed of construction impacts and project updates.
Regional Planning and Coordination
The scale of these infrastructure changes is managed through complex regional planning organizations. The Mountainland Association of Governments (MAG) serves as the regional transportation planning group for urban Utah County, acting as a Metropolitan Planning Organization (MPO). MAG's mission includes regional collaboration to help counties, cities, and towns work together to improve the region through long and short-range planning, including the TransPlan50 regional transportation plan, which looks ahead 30 years for Utah County.
Economic and Community Development
MAG's oversight extends beyond transportation to include community and economic development. The organization administers the Community Development Block Grant (CDBG) programs for Lehi City and Utah County, which are sponsored by the US Department of Housing and Urban Development to develop viable communities and expand economic opportunities for income-qualified individuals. Additionally, MAG works to connect communities with essential services and advocates for local issues to ensure they remain regionally relevant.
Statewide Oversight and Funding
The Utah Transportation Commission, an independent advisory committee appointed by the governor, plays a central role in these developments by prioritizing projects and deciding how funds are spent. The commission oversees the state's transportation priorities, including the assessment of high-priority corridors and the management of the Statewide Transportation Improvement Program (STIP). The STIP is a six-year plan that includes projects on state, city, and county highway systems, as well as projects in national parks and forests.
