Lane and ramp closures continue in south King County this week

This week, significant lane and ramp closures on I-5, SR 516, SR 509, and local roads in South King County will take place through May 17. These closures, part of the SR 509 Completion Project, are designed to facilitate concrete barrier removal and electrical work. Travelers should be aware of up to three lanes of northbound I-5 closing overnight, with additional ramp closures and detours in effect. A temporary closure of South 194th Street will occur for culvert replacement. The SR 509 Completion Project aims to improve regional connectivity by constructing three miles of new tolled highway, with a portion expected to open in summer 2025.

By 2029, the entire project will enhance critical links in Washington's highway network. The Puget Sound Gateway Program, which includes the SR 509 and SR 167 Completion Projects, aims to finalize crucial missing links for the state. Motorists are encouraged to plan ahead and utilize detours during this construction period.
