We are installing modern traffic signal controllers, additional vehicle radar detection equipment and traffic monitoring cameras along Oregon 224 (Milwaukie Expressway) from SE 17th Avenue to I-205 and on Oregon 212 (Clackamas Highway) from Oregon 213 (SE 82nd Drive) to Rock Creek Junction (OR 224).
The new equipment will allow ODOT engineers and technicians to perform remote assessments by monitoring traffic signal performance to better manage congestion and improve safety along these corridors.

Project Benefits
Upgraded traffic signals with modern equipment and additional radar vehicle detection improves safety and travel efficiency by providing needed information to evaluate signal performance.
New thermal imaging sensors installed at five signalized intersections on OR 224 will detect bicyclists and trigger longer green lights, allowing them more time to cross wide intersections.

Construction Impacts
Crews will install new traffic equipment and sensors at night to reduce daytime traffic impacts.
There will be some daytime work on side streets and on other roads near the project area off OR 224 and OR 212. Flaggers will control traffic when needed.
Travelers should expect short delays in the area during construction.
Work hours and schedule are subject to change.
Here's what to expect:
OR 224 and OR 212 Traffic Impacts
- Most work on OR 224 and OR 212 will occur at night.
- Daytime single lane closures Monday through Friday from 9 a.m. to 3 p.m. near the intersection between OR 224 and 122nd Ave.
- Nighttime single lane closures in both directions from 8 p.m. to 6 a.m. on weekdays. Lanes may reopen later on weekend mornings.
- On some nights, a second lane may close in both directions from 9 p.m. to 5 a.m. on weekdays. Lanes may reopen later on weekend mornings.
- Nighttime and daytime shoulder closures in the project area.
Side Street and Intersection Impacts
- Daily daytime work hours from 9 am. to 4 p.m. Monday through Friday.
- Some side streets at each working intersection will have periodic lane closures at night.
- Flaggers will direct traffic at night during work hours when needed at intersections and side streets.
Exit and Entrance Ramp Impacts
- Nighttime single lane closures on exit and entrance ramps from 9 p.m. to 5:30 a.m. on weekdays, from 9 p.m. Friday to 6 a.m. Saturday and from 9 p.m. Saturday to 7 a.m. Sunday.
- Ramp closures from 9:30 p.m. to 5 a.m. on weekdays, from 9:30 p.m. Friday to 5:30 a.m. Saturday and Saturday from 9:30 p.m. to 6:30 a.m. Sunday.
Impacts for People Walking, Rolling and Biking
Sidewalks and crosswalks at intersections on OR 224 and OR 212 will be closed at times with flaggers directing intersections for people moving through the area.
Construction Noise
Residents near each work area may hear some nighttime noise including backup alarms and noise from construction trucks and construction equipment.
Project Schedule
We expect construction to begin in early 2022 and last throughout 2022. The project schedule is subject to change.
We will share more information and project updates through mailings, email alerts and on the project website before work begins.
