If you've ever sat on Mountain View Corridor at 7:45 a.m. watching the light cycle twice before you move, you know exactly what this project is about.
In March 2026, UDOT officially broke ground on the 2100 North freeway — a $621 million, 2.8-mile, six-lane connection between Mountain View Corridor and Interstate 15 in Lehi. Traffic engineers project the road will save east-west commuters 12 minutes in each direction during peak travel times upon completion. Construction is expected to run through late 2028.
That's not just a traffic story. For buyers considering Eagle Mountain or Saratoga Springs — or anyone already living there — it's a real piece of context that should be part of how you're thinking about this area in 2026.
What UDOT Is Actually Building
According to UDOT, the project creates a freeway-to-freeway connection that bypasses the surface streets through Lehi that currently form the bottleneck. Right now, getting from Mountain View Corridor to I-15 requires weaving through signalized intersections — exactly the kind of traffic pattern that turns a 3-mile drive into a 20-minute ordeal at peak hours.
The scope of the project is significant:
- 2.8 miles of new six-lane freeway
- 14 new bridges, including two pedestrian bridges
- Nearly two miles of shared-use paths for pedestrians and cyclists
- Realignment and reconstruction of two miles of existing trails
- Estimated total cost: $621 million
The groundbreaking on March 18, 2026 was attended by UDOT officials and Utah state leaders. KSL called it a "transformational" project for northwest Utah County. Eagle Mountain City confirmed the project officially started in March 2026.
It's also worth noting: a pedestrian detour was already in place on Lehi's Jordan River Trail as early as April 2026 — which means active construction is underway, not just announced.
Why This Matters More for Eagle Mountain and Saratoga Springs Than Lehi
The 2100 North freeway is being built in Lehi, but the people who benefit most are the ones coming from further west. Eagle Mountain and Saratoga Springs sit at the western end of the county. Every commuter from these cities who drives east eventually hits Mountain View Corridor — and right now, Mountain View Corridor hits Lehi's surface streets before it gets to I-15.
The new freeway removes that chokepoint. For an Eagle Mountain resident commuting to Salt Lake City, Provo, or the tech corridor along Silicon Slopes, the Daily Herald reports that the savings add up to roughly 12 minutes each direction — which is 40+ hours of commute time returned to a dual-income household over the course of a year.
The Honest Timeline Reality: You're Buying Into Construction
If you're looking at homes in Eagle Mountain or Saratoga Springs in 2026, this is important: the road doesn't open until late 2028. That means approximately two-and-a-half years of active construction near the Lehi corridor before you see any benefit.
That's not a dealbreaker. But it's something to factor in honestly if your commute tolerance is already stretched thin and you're hoping for immediate relief.
Two things to keep in mind:
The construction itself doesn't directly affect the roads you're currently using. The work is concentrated at the 2100 North corridor in Lehi, not on Pony Express Parkway or Redwood Road. Your daily drive from Eagle Mountain or Saratoga Springs isn't getting worse because of this project — it's just not getting better until 2028.
Buying before infrastructure completes has historically been one of the stronger moves in growing Utah County markets. UDOT notes that this project is designed for the long term — the projected population of northwest Utah County at full buildout is expected to exceed 500,000 across Eagle Mountain, Saratoga Springs, and Lehi. That kind of investment reflects a long-term bet on the area that has generally supported appreciation in comparable Utah County growth corridors.
How the Freeway Fits into the Bigger Picture
The 2100 North freeway isn't the only infrastructure investment happening in northwest Utah County right now. Eagle Mountain and Saratoga Springs are in the middle of a cluster of overlapping projects:
- UTA's on-demand transit service launches August 16 — a $3 rideshare to FrontRunner covering the same 77-square-mile zone
- New businesses continue to open in Eagle Mountain as the city matures from a commuter town into a self-sustaining community
- The Williams Companies power plant — a 520 MW facility to power Meta's data center — brings economic infrastructure alongside the residential growth
These projects don't happen in isolation. They happen because the county has committed to this area growing in a way that requires long-term investment. The freeway is the most expensive signal of that commitment.
What Buyers Should Actually Be Asking
If you're considering Eagle Mountain or Saratoga Springs, the freeway news is background context — not a purchase reason on its own. The questions that actually matter for your decision are still the same ones they've always been: what does your budget get you, which neighborhoods have the strongest fundamentals, and does the timing work for your family?
What the 2100 North project adds to that conversation is a data point about trajectory. This area is not being left behind. The infrastructure investment is real, funded, and under construction.
If you want to understand what that means for a specific purchase you're evaluating — or what neighborhoods in Eagle Mountain and Saratoga Springs are already positioned ahead of the infrastructure completion — that's a conversation worth having.

Does the 2100 North freeway directly affect the drive from Eagle Mountain or Saratoga Springs? The project is located in Lehi, but it directly benefits Eagle Mountain and Saratoga Springs commuters by removing the bottleneck at Mountain View Corridor's connection to I-15. These cities feed onto Mountain View Corridor, which currently has to navigate Lehi surface streets before reaching the freeway. The new connection bypasses those streets entirely.
Does construction affect roads in Eagle Mountain or Saratoga Springs now? The active construction is in Lehi, concentrated at the 2100 North corridor. Roads in Eagle Mountain and Saratoga Springs are not directly disrupted, though secondary effects near the Lehi work zone are possible.
Should I buy in Eagle Mountain or Saratoga Springs before the freeway opens? That depends on your full picture — not just the infrastructure timeline. Historically, buying before major infrastructure completes has supported appreciation in Utah County growth corridors. But your specific neighborhood, price point, and how the commute math works today all matter more than the freeway timeline alone.
How does this freeway connect to the rest of the Utah County road network? The 2100 North freeway creates a direct link between Mountain View Corridor (SR-85) and I-15. From I-15, commuters can travel north to Salt Lake City, the Silicon Slopes tech corridor, and the University of Utah, or south to Provo and Orem.
