When it closes
Parleys Canyon funnels every Salt Lake–to–Park City driver up a steep grade into Wasatch snow, and UDOT runs chain and traction restrictions here through the winter. Heavy snow and blowing snow in the canyon can slow it to a crawl or close it, and truck restrictions are common when the grade turns icy. Check the cameras before you head up.
Are chains or snow tires required on Parleys Summit?
UDOT sets traction and chain restrictions in Parleys Canyon through the winter, and they change with each storm.
How high is Parleys Summit?
About 7,020 feet on I-80 in the Wasatch Range, high enough that the summit can be in a snowstorm while Salt Lake City stays dry.
Where is Parleys Summit?
On I-80 just east of Salt Lake City, at the top of Parleys Canyon toward Park City. Track your mile marker up the canyon with the MileCheck app.
Where are the plows?
