If you've driven through Lehi lately, you've probably noticed the construction along 2100 North. It's not a small project. UDOT broke ground in March 2026 on a $621 million freeway-to-freeway connection between I-15 and Mountain View Corridor, and it's one of the largest single infrastructure investments happening in Utah County right now.
What's Actually Being Built
The project converts 2100 North from its current state, essentially a frontage road, into a full 2.8-mile freeway connection linking I-15 directly to Mountain View Corridor. When finished, it will be six lanes, with 14 new traffic bridges and 2 new pedestrian bridges, plus roughly two miles of shared-use paths for pedestrians and cyclists. UDOT is calling it the first east-west expressway corridor in Utah County.
This connects to work that's already done. In December 2025, UDOT opened a four-mile stretch of Mountain View Corridor between Porter Rockwell Boulevard and 2100 North, complete with five pedestrian bridges and a 12-foot multi-use path. The 2100 North project is the next piece that ties that new road directly into I-15.
What This Actually Means for Commute Times
UDOT's own estimate is that drivers will save about 12 minutes each way during peak travel times once the connection is complete. That's not a small number for anyone commuting from Lehi, Eagle Mountain, or Saratoga Springs toward Salt Lake County or across to the west side of the valley.
The project is also expected to take real pressure off Redwood Road, currently one of the most congested corridors in Utah County, by giving drivers a direct freeway alternative instead of funneling everyone through the same surface streets. A separate project, the Pioneer Crossing Flex Lanes along State Route 145, is also underway to improve east-west travel and is expected to finish sometime in 2026, working alongside this one rather than instead of it.
Timeline
Construction began with an official groundbreaking in March 2026, and UDOT expects the full connection to be complete by late 2028. This is part of a broader roughly $1.4 billion transportation investment UDOT is making across Utah County, so more related road work in the area is likely as pieces of that larger plan come online over the next few years.
What This Means If You're Buying or Selling Near This Corridor
Better freeway access tends to expand the practical commuting radius for a city, and that usually shows up in buyer demand over time, not overnight. For Lehi and Eagle Mountain specifically, cities that have drawn a lot of tech-sector workers commuting toward Salt Lake County, a meaningful cut in commute time can make homes further from I-15 feel a lot more livable than they do today.
It's also worth knowing this if you're buying near active construction right now. Two more years of construction along a corridor you'd drive daily is a real consideration, even if the long-term payoff is strong. We talk through exactly this kind of tradeoff with buyers looking in this part of the county, since what feels like an inconvenience today can be the reason a neighborhood's value climbs in a few years.
