The Pioneer Widening and Discovery Drive Roundabout project has widened Pioneer Street to four lanes with multi-use paths and planter strips, constructed a new roundabout at Discovery Drive, and built N Discovery Drive to a new portion of Pioneer Canyon Drive.
The project also included the construction of 5 major culverts, upgraded water, sewer and storm utilities, and a joint utility trench.
PROJECT STATUS Updated December 11
Pioneer Street: Four Lanes OPEN. Intermittent lane closures may occur during work hours, 7 AM to 5 PM.
Pioneer and Discovery Drive Roundabout: OPEN as roundabout, with intermittent closures as needed to safely complete work in the roundabout during work hours, 7 AM to 5 PM.
Discovery Drive and Pioneer Canyon Drive: OPEN. Occasional intermittent closures may occur during work hours, 7 AM to 5 PM.
53rd Place: OPEN. Occasional intermittent closures may occur during work hours, 7 AM to 5 PM.
The speed limit on Pioneer between Royle and 56th Place is 25 mph, at all times, not just during construction hours. Following this limit keeps everyone—drivers and workers—safe.
Over the next several weeks, you’ll see crews completing finishing touches, including planting about 30,000 plants throughout the corridor and installing artwork in the new roundabout to make this new roadway as beautiful as it is functional.
Thank you for your continued support and patience throughout this project.
The City's Pioneer Widening and Discovery Drive Roundabout project is just one piece 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.
Union Ridge Town Center, anchored by Costco, construction N 56th Place, N 53rd Place and the eastern leg of Pioneer Canyon Drive.
Ridgefield Gateway, which includes McDonalds's, added a turn lane and other improvements to the north side (westbound direction) of Pioneer Street between I-5 and 56th Place. The developer also completed modifications to the Pioneer Street and Interstate 5 interchange to create additional lane capacity.
The map below shows all of the planned and anticipated infrastructure 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.
