Starting Tuesday, September 23, the city’s contractor will be completing top lift paving on the Pioneer Widening Project. There are three closure events scheduled to complete this work:
- Tuesday, September 23, 3 AM to 3 PM: Westbound Pioneer Street will be closed between Royle Road and 56th Place. Access will be maintained to iQ Credit Union, Mountain View Dental and Ridgefield Physical Therapy via N 56th Place and Pioneer Canyon Drive. Westbound Pioneer will re-open by 3 PM for the afternoon commute. View Closure and Detour Map
- Wednesday, September 24, 10 AM: Eastbound Pioneer Street will be closed between Royle Road and 56th Place from 10 AM Wednesday to 5 AM Thursday 9/25. View Closure and Detour Map
- Wednesday, September 24, 8:30 PM: Both lanes of Pioneer Street will be closed between Royle Road and 56th Place from 8:30 PM Wednesday, 9/24 to 5 AM Thursday, 9/25. View Closure and Detour Map
During closures, travelers are encouraged to use the designated detour route, via S Royle Road, Wells Drive, Timm Road, S 6th Way and S 56th Place, or another alternative route.
Business access to Mountain View Dental, Ridgefield Physical Therapy and iQ Credit Union will remain available via Pioneer Canyon Drive. There will be no changes to the 56th Place and Pioneer roundabout during these closures.
After the closures, the traffic pattern will return to one lane open in either direction, with N 53rd Place closed at Pioneer Street and Discovery Drive open.
This is a significant step in the project, and we are excited to be at this point. After this closure, work will continue to install streetlights, landscaping and striping. Once those items are in place, we’ll be able to open up the new roundabout and four lanes on Pioneer.
