PROJECT LOCATION
Preservation of the pavement will take place on 21st Avenue SW between SW 320th Street & SW 339th Street.
PROJECT SCOPE
This project is a roadway pavement overlay. It includes ADA compliance upgrades to our curb ramps, asphalt planing and paving, pavement repairs, and channelization. The project will improve driver safety; improve conditions for non-motorized users with ADA upgrades; and extend the life of the roadway surface.

WHAT TO EXPECT:
Approximately 30,000 cars travel on 21st Ave SW each day, so the City and contractors will do their best to minimize traffic impacts during this project. Expect increased travel times and plan ahead to avoid active construction. In construction zones, remember:
- Slow Down
- Read Signs
- Use alternate routes
Night work will occur for approximately one month. During this time, nearby residences and businesses may be impacted by increased noise, vibrations, flashing lights, and lane closures. Night work during this project is necessary to avoid severe daytime traffic disruptions and improve worker safety.
