Drivers heading south on I-15 through Lehi are now in a new lane pattern at 2100 North (Exit 282), and it isn't going away soon: UDOT expects it to stay in place through May 2027 while crews build the new 2100 North freeway connection, KSL and the Daily Herald reported.
| Where | Southbound I-15 at 2100 North (Exit 282), Lehi |
| What | Traffic shifted to a new lane pattern through the interchange |
| How long | Through May 2027 |
| Why | Utility moves, a soil wall and interchange foundation work |
| Project done | Late 2028 (UDOT, preliminary) |
Why the lanes moved
UDOT says the shift gives crews space to relocate utilities, build a soil-stabilizing wall and begin foundation work for a new I-15 interchange at 2100 North, according to the Daily Herald. The Herald reported that drivers in both directions should expect the pattern to last until May 2027.
UDOT also scheduled overnight lane closures at 2100 North in late October, the Herald reported: crews start closing lanes at 7 p.m., narrow traffic to one lane by midnight and reopen all lanes by 4 a.m. Later closures prepare for overhead signs. Schedules depend on weather.
The project behind it
The 2100 North Freeway project builds 2.8 miles of new freeway on 2100 North (SR-194) in Lehi, linking I-15 and Mountain View Corridor, according to UDOT's project page. UDOT says that once it is finished it should save east-west commuters about 12 minutes each way at peak times. Construction began in spring 2026, and UDOT lists completion in late 2028, a date it calls preliminary. The project also improves pedestrian and bike connections, KSL reported.
What to do
- Allow extra time through the 2100 North interchange, especially at night when lanes may close.
- Check before you go: UDOT Traffic and its app show closures. Our Canyon & Road Status Board now shows UDOT's live construction list for Utah County.
- Ask UDOT: the project hotline is 385-510-2700, or email NWUtahCounty@utah.gov with "2100 North Freeway Project" in the subject line. Put "Updates" in the subject to get project emails.
