Ridgefield's vision for a safer and more efficient transportation network between Interstate 5 and Royle Road will take a significant step forward this summer with the start of the Pioneer Widening and 50th Place Roundabout project. This capital project is one piece of a group of transportation projects in the area designed to improve traffic flow, enhance safety, and accommodate future growth in our vibrant community.
Recognizing the disruptions that these road construction projects will bring, the City of Ridgefield is committed to keeping the community informed every step of the way. Any closures affecting Pioneer Street will be announced at least two weeks in advance, providing ample time for residents to plan alternate routes. Once Costco opens, there will always be a minimum of two access points to alleviate congestion of shoppers and keep traffic moving through the area.
How to View and Receive Traffic Impact Notifications:
- Visit RidgefieldWa.us/Traffic to view current and upcoming closures,
- Sign up for email alerts of upcoming closures at RidgefieldWa.us/Traffic
- Follow the City of Ridgefield on Social Media. Traffic notices for Pioneer Street will also be posted on the City of Ridgefield Facebook page, @CityOfRidgefield, and X account, @CityRidgefield.
While the improvements resulting from the Pioneer Widening and 50th Place Roundabout project are eagerly anticipated and much-needed, we understand that the construction process is very likely to impact your travel to work, school or services. We appreciate your patience and cooperation as we work to create a safer, more efficient transportation network for everyone.

Project Overview
Pioneer Widening and 50th Place construction will consist of five phases, each addressing a specific area of the project. The project was phased strategically to optimize available traffic lanes and minimize delays and detours. Once it opens, there will always be a minimum of two access points to Costco to alleviate congestion. Road construction by the private developer of Costco/Union Ridge Town Center plays a key role in the success of this project, building new roads and paying for the increased infrastructure needs that their project creates.

Phase 0: Private Developer Work
Construction is currently underway by the private developer of Costco/Union Ridge Town Center (URTC). Their work includes:
- A new Collector road, Pioneer Canyon Drive, between N 56th Place and the west end of the Union Ridge Town Center development,
- a new commercial collector, N 53rd Place, between Pioneer Street and Pioneer Canyon Drive,
- an extension of N 56th Place from Pioneer Street to Costco,
- and a new roundabout at Pioneer Canyon Drive and 56th Place. The design concept for the center of this new roundabout was recommended by the new Roundabout Committee and approved by City Council.
This work is anticipated to be complete by the end of August 2024.
Phase 1: N 50th Place
The first phase of the city’s project will begin in June 2024. This phase will include construction of N 50th Place north from Pioneer Street to a western leg of Pioneer Canyon Drive, that will connect with the segment built by URTC.
Two lanes connecting Pioneer Street to the Costco area will open to traffic by the end of August 2024.
Traffic Impacts: Traffic impacts during construction will be minimal to none as this road is not yet open to the public.
Phase 2: N 53rd Place and Pioneer Street Intersection
Phase 2 construction will begin after Phase 1 in September 2024. This phase of construction will consist of widening Pioneer Street and constructing the intersection at the newly constructed N 53rd Place and Pioneer Street. The improved section of Pioneer Street will include two travel lanes and a shared use path, separated from vehicles by a planter strip, in either direction.
In Phase 2, Four Lanes will be Open to Traffic by the end of October 2024.
Traffic Impacts: Single lane and complete closures will be necessary at various times. Pioneer Street closures will be minimized and planned for evening and weekend work whenever possible. Community notifications of planned closures will be provided at least two weeks in advance. Traffic will be routed around the closure via N 50th Place, Pioneer Canyon Drive, and N 56th Place.
Phase 3: Pioneer Widening, 53rd to 56th Place
Construction on the next phase of the project will begin in Fall 2024. This phase will consist of widening a segment of Pioneer Street between 53rd and 56th Place to two travel lanes and a shared use path, separated from vehicles by a planter strip, in either direction.
In Phase 3, Four Lanes will be Open to Traffic by the end of 2024.
Traffic Impacts: Single lane and complete closures will be necessary at various times. Pioneer Street closures will be minimized and planned for evening and weekend work whenever possible. Community notifications of planned closures will be provided at least two weeks in advance. Traffic will be routed around the closure via N 53rd Place, Pioneer Canyon Drive, and N 56th Place.
Phase 4: Pioneer Widening, Royle Road to 53rd Place
The final project phase will overlap with Phase 3. To complete the Pioneer Widening, Phase 4 will consist of widening Pioneer Street to include two travel lanes and a shared use path, separated from vehicles by a planter strip, in either direction. This phase will also include construction of a new roundabout, at Pioneer Street at 50th Place.
In Phase 4, Four Lanes will be Open to Traffic by early Spring 2025..
Traffic Impacts: Single lane and complete closures will be necessary at various times. Pioneer Street closures will be minimized and planned for evening and weekend work whenever possible. Community notifications of planned closures will be provided at least two weeks in advance. Traffic will be routed around the closure via detour routes provided in the advance notice.
Phase 5: Pioneer Canyon Drive, West Leg
The final phase of the project will include a short segment of Pioneer Canyon Drive, west of 50th Place. This segment will provide access to the site of the future Ridgefield YMCA. Phase 5 will be completed Summer 2025 and should not have any major impacts on traffic.
Additional project work, such as sidewalks and landscaping, will continue in the project area throughout the five phases and beyond, until final project completion in Summer 2025.
The Pioneer Widening and 50th Place Roundabout project represents a significant investment in Ridgefield's future. By enhancing our infrastructure, we are laying the foundation for continued growth, prosperity, and quality of life for all residents.
