Utah Transportation Commission Approves $120 Million I-15 South Corridor Widening and Bus Priority Lanes

SALT LAKE CITY, UT — The Utah Transportation Commission voted unanimously to approve a $120 million construction contract with the Utah Department of Transportation (UDOT), funding the expansion of Interstate 15 through the Point of the Mountain technology corridor between Draper and Lehi.

Relieving Silicon Slopes Commuter Gridlock

The engineering project adds continuous Express Lanes in each direction, constructs dedicated Utah Transit Authority (UTA) express bus bypass ramps at 11400 South and 2100 North, and modernizes freeway bridge structures to accommodate high-frequency regional transit. Transportation economists estimate the expansion will save daily tech sector commuters 25 minutes during peak morning and evening travel times.

Governor Spencer Cox and UDOT leadership stated that strategic transportation investments in the Silicon Slopes corridor are vital to sustain Utah’s nation-leading job growth and technological innovation.

Tech Coalition and Transit Rider Feedback

Silicon Slopes tech leaders praised the express bus priority ramps for accelerating public transit adoption among corporate workers.

Regional air quality coalitions highlighted that carpool express lanes encourage multi-passenger commuting and reduce carbon emissions along the Wasatch Front.

Construction Milestones

Heavy shoulder widening and concrete paving operations will commence in October 2026, with project completion slated for summer 2028.
