The planned Highway 20 construction closure east of Sweet Home has been delayed until Sunday, Sept. 11, for traveler safety, the Oregon Department of Transportation announced Thursday evening.
The road will be open Friday and Saturday, Sept. 9-10. Travelers are cautioned to drive carefully with the weather-related power outage planned Friday, and to treat traffic signal without power like a four-way stop. Hot, dry winds may prompt power line shutoffs to prevent fires. Trees and vegetation may be on the road. Careful parking is also advised to prevent vehicle-sparked fires.
Highway 20 will then be closed through Sept. 20 for landslide repair work between mileposts 55.4 and 56.2, east of House Rock Campground.
Daytime closures will continue through October.
ODOT plans to build a retaining wall and to realign and reconstruct a portion of the road that has been damaged by landslides between mileposts 56 and 56.2. It also plans to improve the road surface in portions between mileposts 55.4 and 56.2.
When the road is reopened, work will require daytime single-lane closures from 6 a.m. and 6 p.m., Mondays through Fridays, through October.
Traffic will be controlled by flaggers between mileposts 54 and 57.
