Road Closures Frequently Asked Questions

Full closures of Parleys Canyon (I-80) and other major roads in the Wasatch Back are rare and only occur due to emergency incidents such as crashes or fires. UDOT’s Incident Management Team works to avoid multi-lane closures except when absolutely necessary and will reopen lanes as soon as possible.

There are no avalanche slides in Parleys, so planned road closures for avalanche mitigation are not needed.

Yes, UDOT manages four seasonal roads in the area: SR-65 East Canyon (northeast of Salt Lake City), SR-224 Guardsman Pass (Park City to Brighton), SR-150 Mirror Lake Highway (east of Kamas to near the Wyoming border) and SR-35 Wolf Creek Summit (east of Francis to west of Hanna).

The opening and closure of these roads are dependent on snow and road maintenance resources, but they’re typically closed from November through May or June.
