Last week, devastating flooding across southwestern Colorado prompted Governor Polis to declare a disaster emergency in twelve counties. The severe weather washed out roads and necessitated the evacuation of thousands, adding to a challenging year for Colorado that has included a dismal winter, a dry spring, wildfires, and record summer heat.

Among the most significantly affected routes was Colorado’s Million Dollar Highway (US 550). Heavy flooding on October 22 near the Ophir Pass turnoff, north of Silverton, washed away part of the shoulder and a travel lane. This damage required CDOT to close Red Mountain Pass until 5 p.m. While now open, traffic on US 550 is restricted to one alternating lane, managed by a temporary signal, with additional repairs anticipated in the coming days.

The record rainfall began Wednesday night, October 21, and by Friday, flooding had started across southwestern Colorado. Rainfall totals, as reported by the Durango Herald, reached 5.05 inches in Pagosa Springs, 3.06 inches in Durango, and 3.27 inches in Bayfield. This moisture was fueled by the remnants of Hurricane Trudy.

Communities situated along Colorado’s San Juan River endured several challenging days as heavy rains caused the river to swell to 15 feet on October 23, before it receded to 12 feet later that same day. This subtropical weather system generated significant flooding in Archuleta, La Plata, and several neighboring counties.

County assessments of the damage have identified several hard-hit roads. Colorado Highway 151 near Chimney Rock experienced a complete wash-out of its pavement. US 160 over Wolf Creek Pass sustained damage to culverts and retaining walls. Additionally, US 160 near the Four Corners was closed due to high water at the San Juan River Bridge. Archuleta County Road 500 and La Plata County Roads 334 and 520 also suffered serious damage.

The Governor’s disaster declaration allows the National Guard to assist thousands of residents attempting to escape flooded areas. As of October 26, some Archuleta County residents remained stranded along the heavily damaged County Road 500. State and local crews are actively working to restore access to these areas, though repairs to the washed-out roads could extend for weeks or longer. Residents needing evacuation assistance are advised to call 970-731-2160, while those with general flood questions should direct inquiries to 970-508-9928.
