I5 to Royle Road Transportation Improvements
The City's Pioneer Widening and 50th Place Roundabout project will widen Pioneer Street, construct a new roundabout at 50th Place, and build 50th Avenue north to a new portion of Pioneer Canyon Drive.
When completed, there will be a four-lane roadway along Pioneer Street from just west of Royle Road to I-5, and a new east-west collector roadway (Pioneer Canyon Drive) connecting 50th Place to an extension of 56th Place. This will provide two parallel routes to handle current and future traffic in the area.
Traffic between Interstate 5 and Royle Road is expected to increase as new commercial development planned in the area is constructed and opened. While addressing the necessary improvements for traffic capacity and flow, the City has an opportunity to design the area to be more pedestrian and cyclist friendly.
City Project
| Pioneer Street | This project will widen Pioneer Street to a four-lane section from Rosauers to the 56th Place roundabout. The new segment of Pioneer will include two travel lanes and a shared use path, separated from vehicles by a planter strip, in either direction. |
| Roundabout | A new roundabout will be constructed at 50th Place. |
| 50th Place | 50th Place will be built north to connect to a new east-west parallel route, Pioneer Canyon Drive, being built by the developer of Union Ridge Town Center/Costco. This segment of Pioneer Canyon Drive will connect 50th Place to an extension of 56th Place, also being built by the Union Ridge Town Center and Costco developer. |
| Pioneer Canyon Drive | The City project will include a short western leg of Pioneer Canyon Drive at 50th Place, to provide access to the new Ridgefield YMCA. |
Developer Projects
As demonstrated on the map below, the construction of N 56th Place, N 53rd Place and the eastern leg of Pioneer Canyon Drive will be completed by the developer of Union Ridge Town Center. This project will include the construction of a new roundabout at N 56th Place and Pioneer Canyon Drive. The developer of Ridgefield Gateway will be adding a turn lane and other improvements to the north side (westbound direction) of Pioneer Street between I-5 and 56th Place.
The developer will also construct modifications to the Pioneer Street and Interstate 5 interchange that will create additional lane capacity. This design is currently being reviewed with Washington State Department of Transportation (WSDOT). The improvements will accommodate the expected increase in traffic to the area.
These improvements are expected to be completed in 2024.

Coordination
The City's Pioneer Widening/50th Place Roundabout project is just one piece of of a group of transportation infrastructure improvements planned for the area. Several projects will be completed by private developers, paying for the increased infrastructure needs their projects will create.
The map below shows all of the projects, color coded by whether the project will be done by the City, or by a Developer. This is a conceptual map and does not show exact road alignments.

| 5 | Build N 50th Place as industrial/commercial collector | 2024/2025 |
| 6 | Build N 56th Place as industrial/commercial collector | 2024 |
| 7 | Build S 50th Place as minor arterial | 2024 |
| 8 | Build new east-west collector south of Pioneer | 2024/2025 |
| 9 | Build new north-south connector east of I-5 | 2024/2025 |

The City’s Pioneer Widening/50th Place Roundabout project team has been closely working with the teams for Union Ridge Town Center/Costco, Mountainview Dental, and Ridgefield Gateway to ensure all utilities and road improvements are coordinated both in design and in timing. Some of the developer infrastructure including roads and utilities are underway, and there has been a continuous coordination process between those contractors, the City and Washington State Department of Transportation (WSDOT).
Next Steps
The City’s project is currently in the preliminary design stage as well as working to obtain the needed state and federal permits. The final design will be completed early in 2024 with the project expected to go to bid in the Spring of 2024.

Project Overview:
Pioneer Widening and 50th Place construction will consist of four phases, each addressing a specific area of the project. The project was phased strategically to optimize available traffic lanes and minimize delays and detours. 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 and Pioneer Canyon Drive
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.
Interim traffic lanes in each direction connecting Pioneer Street to the Costco area will open by the end of August 2024. Final roadway work will be completed Summer 2025.
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.
Phase 2 is anticipated complete in late 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.
Phase 3 is anticipated complete in 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 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.
Phase 4 is anticipated complete by 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.
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.
