Getting on SR 99 from in and around downtown Seattle changes with the new SR 99 tunnel.
This video shows how to drive to SOUTHBOUND SR 99 from both the north and south ends of downtown.
Watch our other videos to see what it’s like to drive north into Seattle, drive south into Seattle and how to access northbound SR 99 from in and around downtown Seattle.
The tunnel will be free to use when it first opens, with tolling starting no earlier than summer 2019. After the tunnel opens, it could take weeks or months for traffic patterns to settle down as drivers try different routes to and from their destinations.
