City of Federal Way City Center Access Project
Briefing Sheet
Project Description:
• The City plans to solve the transportation issues accessing the City Center. This plan eliminates critical safety
issues, increases mobility, and allows the planned economic development of the City Center as designated by
the Metropolitan Planning Organization (MPO). The project provides improvements that will modify the existing
interchange of S 320th Street at Interstate 5 (1 -5) in multiple phases, with the southbound off -ramp improvements
already constructed. The project will not only benefit the designated urban center city core, but will address state
and federal highway system issues in this vicinity. The S 320m St at 1 -5 interchange is the sole freeway access
to the City Center and the project is within the U.S. Department of Transportation's Six Interstate Routes
"Corridors of the Future" to Help Fight Traffic Congestion on Interstate 5.
Project Purpose and Need:
In order to enhance access to and circulation within the City Center, the City of Federal Way seeks to improve safety
and reduce congestion on the transportation network with the following:
• Mitigate high collision rates by correcting deficiencies in the existing interchange ramps. Additionally, alleviate
existing and future year congestion while providing safety mitigation at S 320th Street and Interstate 5.
• Increase and distribute vehicle capacity in the local and highway system with additional combined access to
Interstate 5 and new east -west regional arterial connectivity.
Project Benefits that will meet these community needs:
• Reduce exceedingly long delays due to volumes of vehicles, freight, and buses by reducing congestion that
occurs morning, midday and evening peak hours, as well as several hours during weekends.
• Increased mobility in access to the city with this project supports economic development and livability of Federal
Way's City Center Core, a designated Urban Center.
• The project is within the Highest Accident Corridors and Highest Accident Locations in the State. Many collisions
are due to incident - related congestion resulting from spillover traffic impacts at this project location from the
southbound ramp. A substantial decrease of collisions will occur by the project providing relief to the existing
interchange.
