SISTERS, OR -- Those driving between the Willamette Valley and Central Oregon will encounter delays, due to firefighting efforts. Along Highways 22 and 20, from Detroit Lake to Sisters, active wildfires are causing road closures and delays. Those driving Santiam Pass through the Labor Day holiday weekend are encouraged to check Tripcheck.com for the latest traveler information.

Just west of Santiam Pass, the Oregon Department of Transportation is using a pilot car to direct two-way traffic for 1.5 miles. Drivers should expect flagging with a pilot car, between 7 a.m. and 7 p.m. During the day, wildland crews are cutting burning snags, using helicopter water drops and moving equipment, which is impacting highway travel. Both lanes are open overnight, although the situation could change based on fire activity.

Delays are expected to continue over the weekend, as temperatures soar and the fire behavior and fire danger increases.
