The Oregon Department of Transportation has launched a project to remove hazardous trees along Interstate 5 between milepost 135 and 140. Crews will continue the work daily until October 2, 2026, to ensure freeway safety.
Why it matters
Removing diseased or unstable trees near major corridors is a critical maintenance task to prevent roadside accidents and power disruptions. The state is managing the work to mitigate impacts on commuters traveling through the corridor.
Work crews are operating between milepost 135 and 140, with traffic delays expected to remain under 20 minutes throughout the operation. Daily activity is restricted to the window of 7 a.m. to 3:30 p.m.
The players
Oregon Department of Transportation
This is the state agency responsible for the operation and maintenance of the highway system throughout Oregon.
The details
Crews are utilizing rolling slowdowns in both directions of Interstate 5 to manage safety while removing vegetation. Traffic flaggers are positioned at Exit 135, Exit 136, and Exit 138 to regulate flow, while message boards provide guidance for drivers approaching the work zones.
Timeline
September 28, 2026: The project officially began.
September 28 to October 2, 2026: Crews work daily from 7 a.m. to 3:30 p.m.
October 2, 2026: Operations are scheduled to conclude.
Seasonal Patterns
This project follows the maintenance standards set by the Oregon Department of Transportation's Highway Maintenance Standards to preserve safety along critical infrastructure. Regular vegetation management is a standard preventive measure to prevent tree fall during the state's storm season.
Drivers should expect delays up to 20 minutes when traveling through the 5-mile work zone and follow all posted signage. Please remain alert for traffic flaggers and work equipment at Exit 135, Exit 136, and Exit 138.
The takeaway
Travelers should plan for extra time if commuting along the Interstate 5 corridor near Sutherlin and Oakland during the scheduled work hours. Checking local traffic alerts before departure remains the best way to avoid peak delays during this project.
What happens next
The tree removal operations are scheduled to reach completion on October 2, 2026.
