Santiam crash slowed winter traffic

An injury crash involving a passenger vehicle and a semi-truck closed U.S. Highway 20 near Santiam Pass for roughly two hours Monday afternoon, backing up traffic in both directions and underscoring the hazards of winter travel through the Cascade Mountains.

The collision was reported around 12:35 p.m. near milepost 79.5, about a mile east of the summit at Santiam Pass, according to the Oregon Department of Transportation. Authorities shut down the highway while emergency crews responded and advised motorists to seek alternate routes.

Initial reports indicated the passenger vehicle may have lost control before striking the commercial truck. At least one patient was transported by ambulance to St. Charles Bend for treatment. A Life Flight helicopter was placed on standby but ultimately was not needed.

Winter driving through the Santiam Pass corridor is often unpredictable, even during daylight hours. The high-elevation route-one of the primary east-west connections between the Willamette Valley and Central Oregon-frequently sees rapidly changing weather, including snow, ice and sudden drops in visibility. Transportation officials routinely urge travelers to carry chains, check road conditions before departing and allow extra time when crossing the Cascades.

Although Monday’s closure was relatively brief, it caused significant delays for motorists and commercial carriers relying on the highway, a reminder of how quickly travel can be disrupted in Oregon’s mountain passes during the winter months.
