Labor Day travel on U.S. 20

EDDYVILLE/SWEET HOME – The road will be open with no construction closures on the U.S. 20 Pioneer Mountain to Eddyville Project over the Labor Day weekend. The road reopened at 10 p.m. on Thursday, September 1, after work was cancelled by rain, and will remain open until Tuesday, September 6, at 7:30 p.m. Some work will continue off of the existing roadway through the weekend. All work is weather dependent.

 On the east side of Interstate 5, U.S. 20 remains fully closed 26 miles east of Sweet Home at the Sheep Creek Bridge. The U.S 20 Sheep Creek Bridge closure will last through the end of September. The highway is fully closed from milepost 54 to 56.9. The bridge is out. There is no local detour.

  • Eastbound travelers should take U.S. 20 from Lebanon to OR 226 to OR 22, or OR 126 from Springfield.
  • Westbound travelers should take OR 22 to OR 226, or OR 126 from Santiam Junction.

The road is open between Sweet Home and the bridge on the west side and from Santiam Junction to the bridge from the east. Campgrounds and recreation areas are open and accessible. A span of the bridge and abutments are being replaced due to damage from an active slide area.

Schedule changes after Labor Day

U.S. 20 Pioneer Mountain-Eddyville Project overnight road closures will last through the end of October between mileposts 15.84 and 16.91.

  • Saturday night closures are being added, beginning September 10 at 7:30 p.m. These closures are needed to meet the construction schedule, and have been discussed as a possibility since construction began this spring. The road will be closed six nights a week, remaining open for travel on Friday nights.
  • Closure hours will change beginning Wednesday, September 14, moving a half hour earlier at the beginning and end of the closure. Closures will occur Saturday through Thursday between the hours of 7:00 p.m. and 5:00 a.m. The change is needed as daylight hours have shortened. Daylight is needed for safety when blasting is used in construction. Blasts occur in the first hour of closure.
  • There is no local detour. Minimal construction delays should be expected in the area during the day.
  • Travelers should take OR 18 or OR 34 when the roadway is closed.

This project will create five-and-a-half miles of new road, bypassing a 10-mile section of the original U.S. 20 that was built in 1917. For more information, go to:
