The paving project on Highway 11 between Pendleton and Athena is in full swing this week and will continue through the weekend, said the Oregon Department of Transportation.
The project is expected to be complete before the end of next week, said ODOT.
The 16-mile long project will require motorists to plan extra travel time and slow down through the work area. Travelers can expect delays of up to 20 minutes, loose rock on the roadway, reduced speeds, flaggers and pilot cars directing traffic during day and nighttime hours, ODOT?said.
"Chip seal operations result in loose rock on the roadway so everyone will need to drive slowly and plan for delays along the route during the day and through the night," ODOT Public Information Officer Tom Strandberg said.
The pavement project includes applying emulsified oil and rock chip to the roadbed, then rolling it out. The process requires brooming loose rock off the roadway after it has had a chance to cure, typically late at night or in the early morning hours, he explained.
"We know this work can be an inconvenience and our crews and contractors greatly appreciate your support," Strandberg said.
