I-80 | Parleys Canyon Upgrade
CONSTRUCTION UPDATE
July 23, 2025

See UDOT Press Release

As noted in the press release above, we’re expecting a high volume of travelers on I-80 through Parley’s Canyon this weekend due to holiday travel and concerts in Park City. To help accommodate Pioneer Day celebrations, there will be a work suspension on Wednesday and Thursday night (July 23 and 24), and all lanes will remain open during that time.

The good news is that westbound lane closures on Friday (July 25) and Saturday (July 26) won't begin until 10:30 p.m.—giving most concert-traffic time to clear before work starts. Eastbound closures, however, will proceed as scheduled, beginning as early as 7 p.m. Friday and 6 p.m. Saturday.

We encourage drivers to plan ahead using the UDOT Traffic app, leave early, or consider alternate routes such as Provo Canyon or I-84 to ensure a safe and stress-free holiday weekend.

PROJECT DESCRIPTION

The Utah Department of Transportation (UDOT) will resurface I-80, from Lower Parleys Canyon to SR-65 (exit 134). The project objectives are aimed at preserving the life of the road. This paving process will not only help increase the longevity of the road but also address roadway structural integrity and enhance motorist safety by providing a smoother, more durable road surface. The on/off ramps along the route will also be resurfaced. Additional work includes variable drainage enhancements, barrier upgrades, and updated roadside signage and road surface striping.

Know before you go. Check UDOT Traffic before hitting the road

UDOT has established a project-dedicated public involvement team for the I-80 Mouth of Parleys Paving Project.
