Impacts

Traffic Impact

Use caution when driving through the work zone. Expect crews working at night with lane and shoulder closures as needed.

Construction Impacts

Ramp closure:

The connector ramp from northbound OR 99W to the OR 34/U.S. 20 bypass may be closed from 7 p.m. to 6 a.m. on weekday nights. This work will require crews to close the ramp for up to 14 nights that may not be consecutive. The ramp will be open on weekends.​

Our schedule may change, but currently we're planning to close the ramp these nights:

  • Monday, July 20. 
  • Tuesday, July 21.
  • Wednesday, July 29.
  • Thursday, July 30. 
  • Thursday, August 6.
  • August 10 through August 13.

Coming up – bike and pedestrian bridge impacts:

Currently, the multi-use path bridge is open. Our schedule may change, but currently we're planning to close the bike and pedestrian bridge from July 29 through August 14.

During the closure, bike and pedestrian detour signs will be back in place. Make sure you're signed up to get email updates​ from us to find out when.

​You can expect:

  • Most work to happen at night. 
  • Lane and shoulder closures with flaggers directing traffic when needed.
  • Sidewalk and curb ramp closures with pedestrian detours to the nearest available crosswalk.
  • Ramp closures with detours as needed – make sure you're signed up to get email updates to know before they start.
  • Businesses in the work zone to remain open during construction.
  • Construction noise – saw cutting concrete can get loud.
  • Delays. Plan ahead and allow extra travel time.

About

enlarged project map iconThis highway is an important route for commuters and local businesses. The pavement is cracking, rutting and needs to be replaced.  

With this project, we plan to: 

  • Remove current pavement and repave, improving the driving surface.
  • Apply new striping to the road to improve visibility.
  • Upgrade several curb ramps to meet current ADA standards.

We’re planning to build and will have a better idea about the construction schedule and cost as​ we get further into design.
