As of October 2026, UDOT has moved drivers onto a newly built northbound lane of US-189 through Provo Canyon, a milestone in the US-189 Improved project. The project began in October 2025 and is realigning several miles of the highway along Deer Creek Reservoir and widening it to two lanes in each direction between Wallsburg and Charleston. In February, UDOT’s target for finishing was fall 2027. Reporting this month says construction now continues through 2028. If you commute between Utah Valley and Heber Valley, or you’re looking at homes in either, here’s what has changed and what hasn’t.
This stretch matters to a lot of our clients, whether they’re driving to Heber Valley for work, heading up for the weekend, or weighing a home on the Wasatch County side. It’s also one of the few places on that route where traffic has had one lane in each direction.
What’s Done
UDOT announced on October 9 that crews had shifted drivers onto a newly constructed northbound lane. To make the shift, they temporarily reduced the highway to one-way alternating traffic while they placed concrete barriers.
According to UDOT, since construction began crews have used 23,000 tons of asphalt to build 1.8 miles of new road and moved about 1 million cubic yards of earth. UDOT’s Region Three director described months of blasting and building the section in a completely new location.
What’s Being Built
When it’s finished, the project will:
Widen US-189 to two lanes in each direction.
Realign several miles of the highway and reduce curves for better sight lines.
Add longer acceleration and deceleration lanes.
Improve access and parking at the Island Beach Day Use Area.
Add new wildlife fencing to protect drivers and animals.
Replace the stop-controlled intersection at US-189 and SR-113 with a traffic signal.
What’s Next
Upcoming work focuses on the southbound side of the highway and the SR-113 intersection. A UDOT spokesperson told KPCW the new traffic configuration will remain in place through next year.
The Timeline Has Moved
When construction started, UDOT’s stated completion date was fall 2027. This month’s reporting says the work will run through 2028. UDOT hasn’t published a detailed reason in what I found, so treat 2028 as the current expectation and watch for updates.
What to Expect as a Driver
Expect periodic lane reductions and one-way alternating traffic, particularly as crews work on the southbound side. UDOT posts closures and delays on its traffic site and app, and check before heading up the canyon, especially on weekends and holidays.
What It Means for Buyers and Sellers
We don’t have data showing how this project affects home values. What we can say is practical. A safer, wider highway with fewer curves should make the drive more predictable once it’s done, but you’ll deal with construction for at least two more years.
If you’re buying in north Provo, Orem, Lindon or Pleasant Grove and expect to drive to Heber Valley regularly, test the drive at the times you’d actually make it. If you’re buying in Wasatch County, ask about commute patterns. And if you’re selling, buyers who use that route may ask about it, so it helps to know the timeline.
How This Connects to Vesper
The Vesper Amphitheater proposal is at the mouth of Provo Canyon, also along US-189. It’s a different stretch from the Deer Creek construction, and this project doesn’t answer Vesper’s traffic questions. The Vesper development agreement, as drafted, requires state highway access and UDOT approvals, so UDOT is involved in both. We covered where that stands in our Vesper Amphitheater update. For other projects shaping drive times in the county, see our post on what’s being built in Utah County.

Frequently Asked Questions
What is the US-189 Improved project?
It’s a UDOT project that began in October 2025 to widen US-189 along Deer Creek Reservoir between Wallsburg and Charleston. It will add a second lane in each direction, reduce curves, and add a signal at SR-113.
When will the US-189 construction be finished?
Reporting in October 2026 says work continues through 2028. UDOT’s earlier target, reported in February 2026, was fall 2027.
What changed in October 2026?
UDOT announced on October 9 that it had shifted drivers onto a newly built northbound lane. The new configuration is expected to stay in place through next year.
Will there be delays on US-189 in Provo Canyon?
Likely, at times. Crews are working on the southbound side and the SR-113 intersection, and UDOT has used lane reductions and one-way alternating traffic. Check UDOT’s traffic site or app before you go.
What is happening at US-189 and SR-113?
The existing stop-controlled intersection will be replaced with a traffic signal as part of the project.
Does this project affect the Vesper Amphitheater?
Not directly. Vesper is proposed at the mouth of Provo Canyon, a different stretch of US-189 from the construction near Deer Creek. The Vesper proposal would still require state highway access and UDOT approvals.
Will the US-189 project affect home values?
There’s no reliable data on that yet. The project isn’t finished, and any effect on home values would depend on how commute patterns change over time.
