Parleys Canyon (I-80) Road Conditions & Closures
I-80 · UT · closures driven by road-surface conditions
Very low closure risk
Parleys Canyon (I-80) is the main mountain-access corridor for Park City Mountain and Deer Valley. It's a very low-closure corridor, and when it shuts down or restricts traffic, the cause is almost always road-surface conditions. Below: live UDOT status, plus StormDrop's read on when I-80 tends to close and how to time your drive around it.

I-80 / SR-224 (Park City)
RestrictedRoad: Dry | Notices (check timing): High Valley Transit SR-224 (The Bobsled Express) is a bus rapid transit construction project that spans seven-miles from Kimball Junction to Park City Old Town. The project will include segments of dedicated bus lanes as well as new stations along the corridor. Construction got underway in 2026 and is scheduled to be complete summer 2028. 2026 work includes utility upgrades, median removal and replacements, roadway widening and station construction. During construction, travelers can expect periodic lane shifts, shoulder closures, and changing traffic patterns. The project will maintain two-lanes of travel in each direction whenever possible. Work will be paused over the winter months. | Pavement preservation project
When does Parleys Canyon close?
Closure risk
Very low
Typical window
Any time
Typical reopen
~1 hr
Closures here aren't limited to a fixed morning window — they can happen at any time of day during an active storm, usually reopening about about an hour after control work wraps up.
In StormDrop's closure model, risk starts building once a storm cycle pushes past about 24" of new snow and climbs steeply above roughly 36". Sustained wind above about 40 mph adds risk through blowing and drifting snow.
Traction-law restrictions tend to appear well before a full closure — often around 4" of fresh accumulation — so carrying chains or running AWD/4WD with snow tires is the safe default on a storm day.
These are StormDrop's closure-model tendencies and general corridor knowledge — not a published schedule or a guarantee. UDOT makes the real-time call. Always confirm live I-80 status before you go.
Beating the closure
Closures here aren't tied to a set time — build slack into your plan and watch live status all morning.
Carry chains or run AWD/4WD with dedicated snow tires whenever a storm is in the forecast — a traction law can go up before the road ever closes.
Check the live UDOT status above before you leave, and again mid-drive — storm-day conditions on I-80 can flip within minutes.
Have a backup resort or a later-start plan so a control-work delay doesn't cost you the day.
Frequently asked

Closures here aren't limited to a fixed morning window — they can happen at any time of day during an active storm, usually reopening about about an hour after control work wraps up. In StormDrop's closure model, risk starts building once a storm cycle pushes past about 24" of new snow and climbs steeply above roughly 36". Sustained wind above about 40 mph adds risk through blowing and drifting snow.
Do I need chains on I-80?
On an active storm day it's wise to be ready. I-80 through Parleys Canyon can go under a traction law that requires AWD/4WD with snow tires or chains. Carry a set and check the live UDOT status above before departing.
