Southbound I-15 Drivers Are Now on New Pavement in Davis County — and an Exit 335 Closure Is Coming
If your commute runs south on Interstate 15 through Clearfield, the road under your tires changed over the weekend. The Utah Department of Transportation shifted southbound I-15 onto 1.5 miles of new pavement between 5600 South in Roy and 650 North in Clearfield, with crews starting lane closures Saturday evening and the switch fully in place by Sunday morning.
Northbound traffic moved onto its new surface back in June. With the southbound shift done, drivers through this stretch are now on new pavement in both directions — the most visible sign yet of how far the 1800 North Improved project has come.
“If you drive this section of I-15 regularly, the road looks very different than it did even a few months ago,” UDOT Region One Director Nathan Peterson said in the department’s announcement.
What’s next, and what to watch for
Two things on the calendar matter for residents. First, UDOT has a full weekend closure planned for late September on the southbound I-15 off-ramp to 650 North — Exit 335 in Clearfield. If that is your exit, plan an alternate. Second, the next big milestone lands in January, when a new bridge opens at 1800 North and 500 West. Today that crossing sits at the railroad tracks, where drivers stop and wait for trains. The new structure goes over the tracks, so traffic keeps moving.
In between, expect more traffic shifts and side-street closures along 1800 North as the work advances.
The bigger project
1800 North Improved is not just a repaving job. It widens I-15, builds a new interchange in Sunset, widens 1800 North, adds the railroad bridge, builds a multi-use trail and pedestrian bridge, and leaves room for a future Hill Air Force Base entrance gate. UDOT puts the project at roughly 50 percent complete, with a finish expected in fall 2027.
That timeline is worth keeping in mind. Residents in Clearfield, Sunset and Roy have another two construction seasons ahead before this corridor settles into its final shape — but the new pavement in both directions means the roughest driving stretch of it is behind them.
