Engineering: We have completed analyzing options to reconfigure the Key Peninsula Highway NW/Lackey Road NW/Jackson Lake NW intersection. Based on community feedback and further analysis, we have selected Alternative 2, a single lane roundabout. Initial work on the preliminary engineering for this project has begun and County crews have surveyed the project area.

Single Lane Roundabout Selected for Intersection Project
In March of this year, Pierce County hosted an online open house about the Key Peninsula Highway NW/Lackey Road NW/Jackson Lake Road NW intersection project. As of July 2022, Pierce County has selected Alternative 2, a single lane roundabout, for this intersection.
Features may include:
Central island
Truck apron for larger trucks and emergency vehicles to drive onto when navigating the roundabout
Planned improvements to Key Peninsula Highway NW/Lackey Road NW/Jackson Lake Road NW intersection include reconfiguring the intersection into a new roundabout with consideration for the following features:
Non-mountable center island with raised splitter islands and crosswalk cutouts
Truck apron for larger trucks and emergency vehicles to drive onto when navigating the roundabout
6-foot paved shoulders on road approaches to the roundabout
January 2022 to December 2022: Offer online open house to residents about alternatives, select alternative, complete field survey of the roadway, and begin preliminary engineering for the preferred option to reconfigure the intersection.
December 2022 and Beyond: Complete preliminary engineering and right-of-way plans. Funding has not been identified for right-of-way acquisition or construction. Those phases of the project will occur as funding becomes available.
