Traffic Impact

​Expect temporary closures of traffic lanes, interchange ramps, and side streets, primarily at night. Pedestrians—including individuals using mobility devices—will encounter signed, accessible detours. Cyclists will ride in travel lanes with vehicles during shoulder closures.

Construction Impacts

June 21, 2024 update:  
  • The contractor plans to work nights from 9 p.m. to 5 a.m., Sunday through Friday nights. 
  • Expect nighttime lane closures on OR 99W from SW McDonald Street to OR 217 for paving work. Local access and partial driveway access will be maintained.
  • Expect nighttime right lane closures throughout the project area in both directions. 
  • Expect temporary sidewalk closures throughout the project area with ADA-accessible pedestrian detours.​
Construction is underway and will continue through 2024.  We plan to update this website every Friday detailing traffic impacts for the following week. Read our mid-project construction update​ to learn about work completed and view progress photos.

These are the anticipated traffic impacts planned for the duration of construction:
  • Nighttime lane, interchange ramps and side street closures from 8 p.m. to 5 a.m. weekdays and until 9 a.m. on weekends. Watch for travel lanes to be shifted into the center median lane.
  • Temporary sidewalk closures with signed, accessible pedestrian detours.
  • Shoulder closures with people on bicycles riding in the travel lane.
  • Short sections of one traffic lane and shoulder closed for up to 10 days during sidewalk curb ramp reconstruction. 
  • Intersection closure of OR 99W with SW Main/Johnson streets during traffic signal replacement work between midnight and 4 a.m.
  • Temporary closure of Main Street in downtown Tigard from 9:30 p.m. to 4:30 a.m. during pavement rehabilitation work.
  • The following freeway ramps will have a weekend closure: OR 217 northbound off-ramp and on-ramp, OR 217 southbound offramp, and I-5 southbound off-ramp. Only one ramp closed per weekend. Signed detours will be posted.
  • A limited number of weekend lane closures on OR 99W during bridge repair work.

Noise: Construction activities will create some noise during daytime and nighttime hours. This number is available for nearby residents and businesses to help resolve any ODOT noise-related concerns 24 hours a day: 503-294-1389.

Nearby ODOT Projects: A nearby project on OR 217​ is also in construction. The two ODOT teams are coordinating to minimize disruption.


Design Phase: 2019 - 2022
Construction Phase: spring 2023 through 2024



A $41 million investment in safe, accessible travel on OR 99W.
The project improvements increase safety and add connections for people who drive, bicycle, walk and use mobility devices. 

We will create a fully connected sidewalk network in the corridor, smoother and safer road surface, increase bike lane connectivity, and reconstruct sidewalk curbs so they comply with Americans with Disabilities Act standards.
Project Area
The project area begins where OR 99W (Pacific Highway) crosses Interstate 5 near SW 64th Avenue. It continues along Pacific Highway south to SW McDonald Street in Tigard.

​Project Elements
  • New Sidewalks: Build approximately one mile of new sidewalk. When complete, there will be a fully connected sidewalk network between I-5 and McDonald Street.
  • New Bicycle Lanes: Add new sections of bike lanes in both directions to fill in gaps on OR 99W between SW 65th Avenue and SW 72nd Avenue. Add new bicycle detection sensors at signalized intersections.​
  • Highway Paving: Repair and repave nearly three miles of road surface along OR 99W from I-5 to McDonald Street.
  • ADA Upgrades: Upgrade 150 curb ramps to comply with current Americans with Disabilities Act standards.
  • OR 99W intersection with SW Main Street/SW Johnson streets: Build a new crosswalk on the east side of the intersection. Upgrade the traffic signal and build a dedicated left turn lane from SW Johnson Street to northbound OR 99W.
  • Bridge Deck Maintenance: Install waterproofing, repair bridge joints and pave ​two bridges.
As of May 2024, we've built approximately 0.85 miles of new sidewalk, installed 87 new ADA-compliant curb ramps, installed 24 new Accessible Pedestrian Signals at signalized intersections, built 15 retaining walls, and repaved the elevated section of OR 99W over the railroad tracks and Fanno Creek.

Intersection Improvements: OR 99W at SW Johnson Street/SW Main streets 
Build a new crosswalk on the east side of the intersection to improve pedestrian mobility. Build a designated left turn lane for vehicles heading north onto Pacific Highway. To improve traffic flow, a shared lane will allow drivers to continue straight to SW Main Street or turn right onto Pacific Highway. A rebuilt traffic signal supports these changes.
