SR 99 Tunnel Tolling

Updates

  • We are giving away a limited number of free Good To Go! sticker passes to SR 99 drivers. Learn more here.

When will tolling begin?
The SR 99 tunnel is open. Tolling will start in fall 2019, however an exact date hasn't been set. 

How much will the tolls be?
Toll rates will range from $1 to $2.25 with a Good To Go! pass depending on time of day.

What are the options to pay the toll?
There will be three ways to pay the SR 99 tunnel toll:

  • Lowest rate - Drivers with a Good To Go! pass, registered on an account, will always pay the lowest toll rate when using the SR 99 tunnel and other toll roads statewide.
  • 25 cents extra per trip - Drivers who open a Good To Go! account and register their license plate, called Pay By Plate, will pay an extra 25 cents per toll, on top of the Good To Go! pass toll rate.
  • $2 extra per trip - Drivers without a Good To Go! account will pay an extra $2 per toll and will receive their bill in the mail. Bills will be mailed to the vehicle owner registered with the Department of Licensing. 

Who will be exempt from the toll?
Buses, vanpools and emergency vehicles will be able to travel toll-free if they meet specific requirements.

What will be the last exit before a toll is charged?
Drivers who pass through the tunnel will pay a toll. Signs before both tunnel portals (jpg 264 kb) will alert drivers to the approaching tolled-tunnel. At the tunnel’s north end, the final SR 99 off-ramp before the tunnel is at Aurora Avenue and Harrison Street. Approaching from the south, the final northbound off-ramp is at South Dearborn Street.

Why will there be tolls for the SR 99 tunnel?
The Legislature has directed WSDOT to collect tolls in the SR 99 tunnel in order to repay $200 million in construction bonds borrowed to build the tunnel and to fund the ongoing cost of operating and maintaining a safe facility. This funding is part of the $3.3 billion investment to replace the aging Alaskan Way Viaduct and rebuild SR 99 through Seattle.

How will tolls affect Seattle traffic?
After tolling begins, we expect to see a decline in drivers using the tunnel. However, based on the SR 520 Bridge and other toll roads around the country, we also expect to see a gradual increase in tunnel usage over time.

The combination of the SR 99 tunnel and a new, rebuilt Alaskan Way were designed to replace the capacity of the viaduct. The City of Seattle expects to complete the new Alaskan Way in 2021. Given all the changes happening in Seattle, traffic patterns will continue to evolve as people determine their own best ways to get around.
