WHAT TO EXPECT:
Approximately 40,000 cars travel on S 320th St 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.
