Improving Oregon's economy – safer, more reliable, earthquake ready travel

West Linn Northbound OR 43 On-Ramp to

Northbound I-205 Detour Beginning July 21

During this closure, drivers will follow a detour using southbound I-205 to Exit 6 (10th Street), then cross under the freeway to access northbound I-205.

Construction crews are working on the new roundabout connecting OR 43 with northbound I-205. Highway access will be restored when the roundabout is completed late summer 2023. This is one of the critical safety improvements of the project.

Closure: 

• Northbound OR 43 to northbound I-205 on-ramp in West Linn. 

Signed Detour through August 4:  

• Use southbound I-205 to Exit 6 (10th Street), then cross under the freeway to access northbound I-205. This detour has been used multiple times in the past.

Coming soon in August

August 4 to August 28:

• Full northbound/southbound closure of OR 43 between Willamette Falls Drive and freeway ramps.
• Northbound I-205 Exit 8 to OR 43 closure.

Ongoing Traffic Impacts 

• I-205 northbound and southbound nightly periodic lane closures between Exit 8 and Exit 9 from 10 p.m. to 5 a.m. through September 2023; I-205 remains open. 45 mph speed limit is enforced within the construction area.

• Periodic lane and turn lane closures at OR 43 and Willamette Falls Drive intersection between 8 p.m. and 6 a.m., Monday - Friday.
• I-205 on-ramp from OR 213 vehicle width restrictions.

• Clackamette Drive single lane closure with temporary signal and flagger through late 2023. 

• OR 99E shoulder lane closures through late 2023. Northbound OR 99E auxiliary lane closure through Aug. 2023.

River Impacts 

• The Willamette River remains accessible during Abernethy Bridge construction; the Sportcraft Boat Ramp is open.

• 'No wake' zones are in place through the bridge construction area on the Willamette River and will remain until 2024. 
• River users will notice several large barges anchored in the river and are required to stay 200 feet away from the barges. River users are urged to use extreme caution. All boaters must travel between the green and red buoys.

Bike and Pedestrian Impacts

• The pedestrian stairway from Willamette Drive to Territorial Drive in West Linn closed through summer 2023. Use approximately one half-mile signed detour via Mill Street.

• Bike and pedestrian routes through construction zones are in place. Pedestrians and cyclists need to use caution when traveling through the project. Follow signs and stay alert.

Construction has started on the project’s first phase and will last through 2025. You can visit Tripcheck.com for real-time traffic impacts. Stay safe out there. Pay attention to signs and travel safely through the construction zone.

About the project

The I-205 Improvements Project is part of a larger regional effort to manage congestion, increase predictable travel times and reduce crashes. Project improvements will allow the I-205 corridor to remain open and passable following a major earthquake. A safer, less congested corridor will play a critical role in a healthy Oregon economy.
