Your free taste of the new State Route 509 (SR 509) expressway is about to end. Tolling on the first segment of the road begins Monday morning.

The new SR 509 expressway opened in late June. It is the first mile of the new expressway, connecting I-5 to 24th Avenue South in SeaTac. Eventually, the expressway will go all the way to 188th Street, connecting with where SR 509 ends today, near the southwest corner of the airport.

About 17,000 vehicles a day use the new road every weekday.

“Definitely people are using it,” Washington State Department of Transportation (WSDOT) spokesperson Lauren McLaughlin said. “They’re checking it out. We’ve heard from some people that it’s a nice little quick jump right off I-5 to their house or to their community. So there’s definitely some fans of it.”
