2025 finds UDOT directing $1.68 billion in new and ongoing transportation construction projects across state

Earlier this year, the Utah Department of Transportation (UDOT) unveiled an expansive slate of 2025 construction initiatives totaling nearly $1.68 billion, with plans to kick off 152 projects and continue 145 others aimed at enhancing safety, mobility and multimodal connectivity across the state.

“Every day, Utahns are out driving to work, picking up kids, heading to the mountains or just getting where they need to go,” said UDOT Deputy Director Lisa Wilson. “Our job is to make sure those trips are as safe and smooth as possible. These projects might cause some short-term delays, but in the long run, they’ll mean better roads, less congestion and a safer and more reliable way to get around — no matter how you travel.”

UDOT urged drivers to plan ahead, obey work-zone speed limits and anticipate shifting traffic patterns during the busy build season.

New Priority Projects Underway

• 1800 North/I-15 Interchange — Davis County ($385 million).

In Clearfield, work began in March to build a new interchange, widen 1800 North to 2000 West, and construct an overpass at 500 West to span the railroad. Additional groundwork will prepare for a future Hill Air Force Base gate. Completion is expected in fall 2027.

• I-84 Bridges in Weber Canyon — Morgan County ($52 million).

The project replaces two aging bridges over the Weber River and Union Pacific Railroad. A new eastbound bridge will be built to reroute traffic before replacing the westbound span. Construction is set to last two years.

• I-215 Resurfacing — Salt Lake County ($190 million).

Crews will repave three miles of I-215, 14 miles of associated ramps and 22 bridges between SR-201 and North Temple. A modern drainage system will extend pavement life by an estimated 15 years. The project spans two years.

• I-80/SR-36 Widening — Tooele County ($38.4 million).

Work includes adding an eastbound auxiliary lane on I-80 and a new northbound lane on SR-36 north from Stansbury Park. The corridor enhancement is projected to conclude by summer 2026.

• Geneva Road Expansion — Utah County ($34.4 million).

Geneva Road will be widened to two travel lanes in each direction plus a center turn lane. New sidewalks, bike lanes and a 10-foot shared path will also be added. The project begins in summer and finishes by fall 2026.

• US-189 Provo Canyon — Wasatch County ($53.1 million).

Widening the highway to four lanes, creating a signalized intersection at SR-113 and enhancing day-use area access are central to the project, which includes wildlife protections. It is scheduled for late winter 2026 completion.

• US-6 Chicken Hollow to Tie Fork — Utah County ($59.9 million).

The plan expands from two to four lanes, adding acceleration/deceleration lanes and a center median. Improved drainage will point to an expected fall 2027 completion.

• US-191 Passing Lanes — Duchesne County (North of Summit, $30.75 million).

A two-mile passing lane, enhanced shoulders, chain-up zones, guardrails and fencing are among the improvements. Construction is active and set to conclude next year.

• I-15 Climbing Lane — Iron County ($90.3 million).

A long northbound climbing lane spans 13 miles from Kanarraville Rest Area to the South Cedar interchange. The project also widens to three lanes and installs a roundabout at Exit 51. It will wrap in December 2026.

Ongoing Major Projects Continue Through 2026

• 5600 South Mobility — Weber County ($361 million).

The third phase includes reconstructing 5600 South and its I-15 interchange through Riverdale and Roy, concluding in summer 2026.

• Bangerter Highway Interchanges — Salt Lake County ($415.3 million).

Four new interchanges at 9800 South, 13400 South, 2700 West and 4700 South are underway to eliminate traffic signals, all due by year’s end.

• Midvalley Express Bus Rapid Transit — Salt Lake County ($104.1 million).

UTA, supported by UDOT, is starting a seven-mile all-electric BRT line featuring bus-only lanes, 15 stations and signal priority. Work will run through fall 2026.

• Mountain View Corridor Extension — Utah County ($466 million).

Four new miles of freeway connect Lehi’s 2100 North to Herriman’s Porter Rockwell Boulevard, with a new bridge at Redwood Road, wildlife fencing and a multi-use trail. Completion is slated for spring 2026.

• SR-162 & SR-262 Enhancements — San Juan County ($152 million).

Projects along the Energy Corridor include paving, fiber-optic cables, cattle guards and drainage upgrades, continuing into spring 2026.

Statewide Overview: Network Build-Out and Preservation

UDOT’s 2025 portfolio reflects a coordinated approach to address both new infrastructure and maintenance of vital corridors. While major capacity upgrades feature prominently, repaving and drainage projects aim to extend roadway lifespans and improve ride quality.

The agency also continues efforts to build multimodal linkages, including trails and sidewalks alongside key corridors — including approaches to UTA rail and BRT lines — signaling a commitment to complete transportation networks.

What Drivers Can Expect

Duration & Disruption: Most major projects span multiple years, concluding in 2026 or 2027; certain phases may require lane restrictions, ramp or overnight closures and traffic shifts. UDOT stresses that weather-dependent work may affect schedules.

Safety: With heavy equipment zones and temporary layouts across the state, motorists are urged to slow down and practice heightened caution.

Planning Ahead: UDOT recommends checking its online traffic portal or using its app for real-time updates. Signing up for travel alerts and following the agency on social platforms offer an extra layer of preparedness.

Looking Ahead: Vision for 2025 and Beyond

UDOT’s strategy balances capacity expansion with preservation. Projects like the Geneva Road widening and US-6 corridor improvements deliver community connectivity, while multi-modal investments — from shared paths to bus-only lanes — support Utah’s rapid growth in population and vehicle traffic.

In future years, planners point to growing congestion challenges along key corridors like I-15, I-80 and Legacy Highway, where environmental reviews and funding considerations will shape major expansions. The agency’s ongoing work, including enhanced freeway markings and upgraded bridge structures, supports its larger modernization agenda.

UDOT advises motorists to deal better with road construction by using UDOT’s online traffic portal and smartphone app, allowing extra travel time during work hours, and by following UDOT on X, Facebook and Instagram for alerts and updates.
