Ogden Valley Road Closures & Restrictions
Plan ahead
UDOT works with Powder Mountain Ski Patrol for avalanche mitigation on Powder Mountain Road (SR-158). This road is fully closed to the public when avalanche mitigation is in progress.
Check out the traffic dashboard, the UDOT Traffic Cameras, digital signs and road weather forecasts to learn about road conditions.
Ogden Canyon Restrictions
Vehicles longer than 50 feet are not permitted to travel in Ogden Canyon (SR-39 between the canyon mouth and Pineview Dam). UDOT implemented this safety measure in September 2025, after a study discovered that vehicles over a length of 50 feet cannot travel through some sections without encroaching on the opposite lane.
To travel between Ogden and Huntsville, these vehicles must reroute using Weber Canyon (I-84) and Trappers Loop (SR-167). The North Ogden Divide should NOT be used as an alternate route; this county road is a more difficult route than Ogden Canyon with challenges such as steep drop-offs, sharp curves, and rockfall.
MONTE CRISTO HIGHWAY (SR-39) CLOSING FOR WINTER
Starting Tuesday, Dec. 2 at 2 p.m., Monte Cristo Highway (SR-39) is closed for the winter. The closure is in effect between milepost 37, just east of Huntsville near Ant Flat Road, and milepost 56, located near Woodruff in Rich County.
During the closure, motorists who would normally use the Monte Cristo Highway to cross the Monte Cristo summit should plan on using alternate routes. Recommended detours include US-89 through Logan Canyon, or a combination of Utah SR-16, Wyoming SR-89, I-80, and I-84 to access communities east and west of the summit. When UDOT closes the highway, it will remain out of service until at least spring.
Due to its high elevation, the Monte Cristo Highway can be impacted by heavy snowfall in a matter of hours and typically closes from late November through May.
