Project-Details

To reduce traffic impacts during the day on OR 224, most construction work will occur at night, and at least one lane will remain open in each direction on OR 224 during the day. Detour routes are posted below.

• Directional closures (all lanes in one direction) and on/off ramp overnight closures are anticipated:
• Up to 40 nights total, spread throughout the project area during 2025 and 2026.
• Detour routes will be posted online and on reader boards on OR 224 when closures occur.
• Some curb ramp work—to make them Americans with Disabilities Act (ADA) compliant—will occur both during the day and night.
• Sidewalks will have ADA–accessible detours.
• Speed limits may be reduced during work times.
• There may be closures of Monroe Street.

We will minimize nighttime noise when possible. Nighttime construction noise will occur between 6 p.m. and 7 a.m. People who live or work near the project areas may hear periodic construction noise from heavy equipment, construction trucks, and tools. The Nighttime Noise Hotline: 503-294-1353 is available for residents and businesses to help resolve any ODOT noise-related concerns 24 hours a day.

We anticipate construction from spring 2025 through summer 2026.

We’re developing the improvements at SE Monroe Street in coordination with the City of Milwaukie’s Monroe Street Greenway Plan.

The work at the intersection of OR 224 and SE Monroe Street is designed with input from the City of Milwaukie's Monroe Street Greenway Plan. These improvements increase safety for people biking and pedestrians, by reducing intersection conflicts with vehicles and upgrading signals, signage and operations.

Key Elements and Benefits

• Improvements at SE Monroe Street intersection will include upgrades to the traffic signals and construction of a new median island that will restrict vehicles to right-only turns from SE Monroe Street in support of the City of Milwaukie’s Monroe Street Greenway Plan.
• The speed limit will be reduced to 35 miles per hour for the half mile between Harrison and Oak Street. For 24/7 regional traffic updates: tripcheck.com
• Improvements to intersection curbs, including curb ramps and pedestrian push buttons to increase safety and accessibility for pedestrians and people biking.
• Upgraded signs, pavement markings, bridge joint replacements, and guardrails to boost safety and improve visibility.
• The new pavement will be smoother and extend the highway’s lifespan.
  

• Safety improvements for pedestrians and people biking and rolling throughout the corridor and at SE Monroe Street Greenway intersection with OR 224.
  
• Crosswalk push buttons will be easier to reach for everyone, including people using mobility devices. Intersections will meet current ADA standards.
• New pavement will extend the highway's lifespan. Doing work now prevents having to spend more in the future on delayed repairs.
  
• Signs and striping improve safety and increase visibility, especially for traveling in darkness and rain.
• New guardrails meet current standards for improved crash safety.
