Drivers on eastbound State Route 516 in the Kent, Des Moines and SeaTac area need to be prepared for a temporary change in how they enter northbound I-5.
Beginning 10:00 p.m. Tuesday, February 18, the existing eastbound SR 516 loop ramp to northbound I-5 will close for four months. Contractor crews working for the Washington State Department of Transportation (WSDOT) will rebuild the ramp as part of the SR 509 Completion Project.
While the ramp is closed, drivers will be redirected to a temporary left turn lane and traffic signal just east of the I-5 overpass beginning at 4:00 a.m. Wednesday, February 19. This will allow eastbound travelers to safely turn left across SR 516 and enter a temporary ramp to northbound I-5.
Signs warning travelers to stay to the left will be posted.
The existing loop ramp is being rebuilt so that its entrance will align with an intersection where other ramps to and from northbound I-5 will be located. It will also remove some of the sharp curve in the ramp.
I-5/SR 509 Completion Project information
Improvements at the I-5/SR 516 interchange are part of the SR 509 Completion Project. The project builds 3 miles of new tolled highway between I-5 and South 188th Street near the south end of Seattle-Tacoma International Airport. The new highway will be completed in stages. The portion under construction between I-5 and 24th Avenue is scheduled to open in 2025. The final stage will build the remaining 2 miles of the expressway between 24th Avenue South and South 188th Street. The entire project is planned for completion by 2029.
