In 2024, the Utah Department of Transportation (UDOT) embarked on a transformative journey, completing over 138 projects valued at approximately $1 billion. These initiatives spanned from major highway expansions to cutting-edge technology implementations, enhancing safety, connectivity, and sustainability across the state.

Revolutionizing Mobility for a Brighter Tomorrow

A New Era of Connectivity: The West Davis Highway

The completion of the West Davis Highway stands as a testament to UDOT’s commitment to innovation and efficiency. Spanning 16 miles from Farmington to West Point, this four-lane divided highway not only improved access but also accelerated regional development by six months ahead of schedule. The project included nearly 10 miles of new trails that seamlessly connect existing regional paths, promoting active transportation. Environmental preservation was a priority, with 1,110 acres of wetlands near the Great Salt Lake safeguarded.The highway’s design incorporates modern infrastructure elements that cater to both vehicular and non-motorized traffic. Enhanced safety features ensure smoother travel experiences, while the integration of multi-use trails fosters a healthier, more connected community. Residents now enjoy greater mobility options, contributing to an overall improvement in quality of life.

Strengthening Critical Infrastructure: Bridge Rehabilitation

Bridge maintenance is crucial for sustaining Utah’s transportation network. In Salt Lake County, UDOT undertook significant bridge rehabilitation efforts, extending the lifespan of 19 vital bridges. This included critical routes leading to Salt Lake International Airport and spanning major highways like I-80, Bangerter Highway, Redwood Road, SR-201, and SR-202. The investment ensures these structures remain safe and functional for years to come.Moreover, UDOT invested $14 million in repairing 32 bridges along I-15 in Salt Lake County. Crews addressed deck issues and replaced joints on six bridges, improving structural integrity and reducing maintenance costs. These enhancements are part of a broader strategy to maintain and upgrade critical infrastructure, ensuring reliable transportation for residents and visitors alike.

Enhancing Urban Mobility: Intersections and Expansions

Urban areas benefit significantly from improved traffic flow and accessibility. In Washington City, UDOT opened a new interchange on I-15 at Main Street, facilitating easier access to the rapidly-growing region. The project widened I-15, adding lanes in each direction, which has greatly enhanced mobility and reduced congestion.Similarly, Pleasant Grove Boulevard received substantial upgrades, including additional left-turn lanes, new traffic signals, and resurfacing of North County Boulevard. These changes have streamlined traffic patterns, making daily commutes more efficient. The project also focused on pedestrian safety, installing enhanced lighting and crosswalks, thereby fostering a safer environment for all road users.

Promoting Active Transportation: Trails and Pedestrian Safety

Active transportation plays a pivotal role in creating sustainable communities. UDOT invested heavily in expanding trail networks, connecting disparate regions and promoting healthier lifestyles. For instance, the Legacy Parkway Trail now links Emigration Trail, offering residents uninterrupted access to scenic routes and recreational activities.In Provo, the 300 South improvements introduced bike lanes, pedestrian paths, and enhanced safety features such as signalized intersections and better lighting. These additions encourage walking and cycling, reducing reliance on motor vehicles and contributing to environmental sustainability. The city’s infrastructure now supports a diverse range of transportation modes, catering to the needs of all residents.

Leveraging Technology for Safer Roads: V2X and LiDAR

Technology is revolutionizing transportation safety. UDOT secured a $20 million federal grant to implement Vehicle-to-Everything (V2X) technology, enabling seamless communication between vehicles, infrastructure, and pedestrians. This innovation enhances mobility and safety, particularly for emergency and maintenance vehicles, by providing real-time data and alerts.Furthermore, UDOT pioneered the use of LiDAR technology at intersections, creating detailed 3D models of traffic movements. Unlike traditional detection methods, LiDAR offers comprehensive visibility, allowing engineers to identify and address potential hazards proactively. This advanced technology sets a new standard for intersection safety, demonstrating UDOT’s commitment to leveraging cutting-edge solutions.

Sustainable Solutions: HiMod Asphalt and Avalanche Mitigation

Sustainability remains a cornerstone of UDOT’s initiatives. The introduction of HiMod asphalt on US-6 in Spanish Fork exemplifies this commitment. This durable, weather-resistant material extends pavement life while reducing maintenance needs, ultimately saving taxpayer dollars. The innovative paving process halved labor and time requirements, delivering superior compaction and durability.Additionally, UDOT installed Wyssen Avalanche Towers in Little Cottonwood Canyon, enhancing avalanche mitigation efforts. These remotely-triggered towers drop explosives to prevent snow accumulation, ensuring safer winter travel. By adopting such measures, UDOT safeguards mountainous regions and protects travelers from natural hazards.
