Shepard Lane Interchange in Farmington: What's Open Now?

If you drove through the Shepard Lane area on June 29 and saw four open lanes running in each direction for the first time in two years, you'd be forgiven for thinking the whole thing was finally behind you. Then July 7 rolled around and Park Lane shut down completely between I-15 and US-89 for two straight weeks. Anyone who hadn't been following the fine print assumed it was more of the same road work dragging on.

It wasn't. That closure was building something that has never existed at this intersection: a direct underpass connecting the Farmington FrontRunner station to Park Lane and Lagoon Amusement Park on the other side of the freeway. The vehicle interchange and the pedestrian infrastructure are two different halves of the same $151 million project, running on two different timelines, and most residents have been lumping them together as one long inconvenience. That's the part worth untangling, because it changes how you should read every closure notice between now and the end of the year.

What Actually Opened on June 29

The Utah Department of Transportation fully opened the new North Station Lane interchange on June 29 at 9 a.m., after the intersection had been running as a partial, single-lane crossing since the prior November. What opened that morning was a genuine upgrade from the old Shepard Lane overpass, not just a repaired version of it:

• Four travel lanes in each direction, up from the narrow two-lane bridge that stood there for decades
• A 10-foot multi-use path on the north side
• Six-foot sidewalks on the south side
• Four-foot bike lanes in both directions
• New signalized intersections at both ends, replacing the temporary four-way stop that had been in place since November

That single stretch of I-15 through Farmington carries roughly 163,000 vehicles a day, a number that has climbed as the North Station Business Park and Station Park retail center have pulled more traffic into the corridor. The old two-lane overpass, first built decades before either of those developments existed, simply wasn't sized for what the area has become.

The bridge itself is a bigger engineering story than most drivers passing over it will ever know. Wadsworth Brothers Construction, the Draper-based firm that designed and built the project alongside engineering firm Horrocks, installed more than 7,200 linear feet of steel beams weighing about 3.3 million pounds to span I-15 along with the active Union Pacific Railroad and Utah Transit Authority tracks running beneath it. Crews used cranes ranging from 60-ton to 450-ton capacity, timing much of the heaviest lifting for overnight weekend windows so the freeway itself could stay open during the week.

The Underpass Nobody Was Watching For

The vehicle bridge is the part everyone noticed. The part most residents missed is the pedestrian underpass at Park Lane, which is arguably the more useful piece of the project for anyone who doesn't drive everywhere.

That two-week closure in July, from July 7 through July 21, wasn't patchwork on the old road. It was ground-up construction of a new multimodal path connecting the west side of I-15, where the FrontRunner station sits, to Park Lane east of US-89, which is the direct route to Lagoon. Before this project, there was no dedicated walking or biking connection between the train station and the amusement park side of town. If you got off FrontRunner and wanted to walk to Lagoon or into the Park Lane corridor, you were sharing the shoulder with freeway traffic.

UDOT Region One Communications Manager Mitch Shaw has described the broader project's intent as giving "families, businesses and neighborhoods a more reliable way to get around," language that applies just as much to the person walking off a train as the driver crossing the new bridge. Wadsworth Brothers' senior project manager, Layne Fullmer, has pointed to the same connectivity goal from the roadway side, noting that the redesigned interchange ties more directly into the West Davis Corridor and improves east-west movement generally, not just for cars but for the sidewalks and trail now running alongside them.

What's Still on the Calendar

A late June project update put the job at roughly 75 percent complete, with UDOT and Wadsworth Brothers targeting a full finish by the end of 2026. Here's the shape of what's already happened and what's likely still ahead, based on the closures announced so far:

The remaining work through fall focuses on the southbound I-15 on-ramp at North Station, finishing the pedestrian bridges and underpass at Park Lane, final pavement, and median work. Expect more overnight and weekend closures rather than daytime lane reductions, since that pattern has held for nearly every major milestone on this project so far, from the original bridge deck pour to the recent sign removal work.

Why One Overpass Took This Long

Part of what's made this project feel endless is the site itself. UDOT has been building in a footprint where I-15, US-89, Legacy Parkway, and an active rail corridor all converge within a few hundred feet of each other. Wadsworth Brothers' project superintendent, Dustin Belnap, has described the sequencing involved in even the demolition phase, closing southbound I-15 one weekend night and northbound the next to safely bring down the old bridge without shutting the freeway down during the week. The new bridge required six pier caissons, with two of the pedestrian bridges supported on single-column piers to keep the footprint tight against the railroad right-of-way. Crews coordinated daily with on-site Union Pacific flaggers just to keep work moving without interrupting train traffic.

None of that shows up when you're sitting at a red light wondering why the shoulder is closed again. But it explains why a project that looked, from the outside, like "fix one bridge" has taken from spring 2024 into an expected winter 2026 finish.

What This Means for Your Week

If you live on the east side of Farmington and commute toward Station Park or downtown, the North Station Lane interchange is your best bet now that it's fully signalized and running four lanes each way. Park Lane is the one to watch for surprise closures through the fall, since that's where the remaining underpass and pedestrian bridge work is concentrated. If you're planning a Lagoon trip via FrontRunner once the underpass opens, that connection is new territory for the city, not a restoration of something that used to be there.

The practical habit worth building for the next few months: check the UDOT Traffic app or the UDOT Shepard Lane project page before a Friday or Saturday night drive through this corridor, since that's when the remaining work tends to land. The pattern has been consistent enough that a five-minute check before a weekend trip has been the difference between a normal drive and an unplanned detour through Kaysville.

Following a project like this closely isn't really about traffic. It's about understanding how a neighborhood's connections are changing, which streets are about to carry more weight, and which ones are quietly becoming easier to walk or bike. That's the kind of detail Orson Whitmer tracks in Farmington and the rest of Northern Utah, not because it's flashy, but because it's the texture of what makes a place work day to day.
