The Utah Department of Transportation announced July 24, 2026, that State Route 153 is closed indefinitely due to damage from the Cottonwood Fire and flooding. The closure affects the segment of the road between Junction and Puffer Lake, following the destruction of culverts underneath the highway by the blaze that burned 150 square miles in late June.
Fire Damage and Environmental Conditions
The decision to close the roadway comes after the Cottonwood Fire significantly impacted the terrain northwest of Junction, Utah. As reported by NASA Science, the fire was one of the most destructive and largest wildfires in the region during the 2026 season. Satellite imagery from Landsat 8 and Landsat 9 captured the extent of the damage, showing a large brown patch of blackened vegetation spanning much of the rugged terrain along the Beaver River on June 29, 2026.
According to NASA, the fire's intensity was exacerbated by a winter of below-average snowpack and an unusually warm, dry start to the summer. These conditions led the National Interagency Fire Center to warn of an elevated risk for wildfires across the Great Basin and parts of the Rockies throughout July 2026. The Cottonwood Fire became a primary driver of this risk, charring a massive area of mountainous landscape.
Infrastructure and Flooding Impact
The impact of the fire extends beyond charred vegetation. The Utah Department of Transportation confirmed that the fire melted culverts located underneath State Route 153. This structural damage, combined with subsequent road damage caused by flooding, has rendered the Mount Holly section of the highway unusable for the foreseeable future.
This specific stretch of SR-153 runs from west of US-89 in Junction to Puffer Lake. Because the damage to the infrastructure is significant, the state has moved the status of the road from a seasonal closure to an indefinite closure.
Regional Wildfire Context
The Cottonwood Fire was part of a larger, highly active wildfire season in Utah. By July 7, 2026, firefighters were working to contain nearly three dozen large, early-season wildland fires across the western United States. Utah was noted as being among the most active states during this period, with fires having charred a total of 558 square miles.
In terms of scale, the 150 square miles burned by the Cottonwood Fire made it one of the largest and most destructive fires in the country during the first half of the year. It nearly matched the scale of the Babylon fire in eastern Utah, which was another major event during the summer of 2026.
Seasonal Road Status Summary
While SR-153 remains closed indefinitely, other seasonal roads in the region are following standard winter closure protocols. The Utah Department of Transportation maintains a list of roads that typically close between November and May or June, depending on weather conditions.
As of late July 2026, several other routes remain open until the fall, including SR-39 Monte Cristo, SR-65 East Canyon, and SR-190 Guardsman Pass. Travelers are advised to check with local authorities for information regarding non-state maintained routes, such as the Nebo Loop or Pine Canyon, which may have different seasonal closure schedules.
