As of June 22, 2026, the primary road construction activity impacting the Interstate 15 corridor in Lehi centers on the Utah Department of Transportation’s 2100 North Freeway Project. This $621 million effort, which officially broke ground on March 18, 2026, involves building a new 2.8-mile freeway segment along 2100 North (SR-194) to create a direct, stoplight-free connection between I-15 and the Mountain View Corridor.
Project scope and goals
Construction on the project started in spring 2026 and is slated for completion in late 2028, though that timeline remains preliminary. Work includes mass excavation, sewer line installation, fencing along trails, and utility relocations. A notable temporary impact occurred on May 15, 2026, when Rocky Mountain Power crews performed power line work across I-15 near 2100 North, resulting in lane closures beginning at 9 p.m. and a full freeway closure from midnight to 5 a.m. Traffic was detoured to nearby exits during that period.
Current I-15 traffic status
No additional major or ongoing lane closures on mainline I-15 through Lehi are detailed in current UDOT project announcements. Earlier widening of I-15 in the Lehi area, part of the Technology Corridor project between Lehi Main Street and SR-92, was completed in 2020, with six lanes open in each direction since that time.
Traveler resources and benefits
UDOT directs travelers to its real-time resources, including the UDOT Traffic website and mobile app at udottraffic.utah.gov, for the latest camera views, construction alerts, and delay information. The agency notes that construction impacts can change, and drivers should plan accordingly during peak travel periods. The 2100 North project aims to reduce east-west commute times by about 12 minutes once complete, addressing growth in northwest Utah County.
