SR 99 tunnel toll collection in Seattle begins Nov. 9

Truckers driving through Seattle may have noticed the SR 99 tunnel is open. Driving through it is free for now, but that will all change on Nov. 9.

According to the Washington State Department of Transportation, tolling in the SR 99 tunnel will begin Nov. 9. Five-axle vehicle toll rates will be (Monday through Friday):

• 6 a.m. to 7 a.m. – $8.15 by mail or $3.15 with Good To Go pass.
• 7 a.m. to 9 a.m. – $8.75 by mail or $3.75 with Good To Go pass.
• 9 a.m. to 3 p.m. – $8.15 by mail or $3.15 with Good To Go pass.
• 3 p.m. to 6 p.m. – $10.65 by mail or $5.65 with Good To Go pass.

Although the Good To Go pass offers the lowest rate for the SR 99 tunnel toll, drivers without one can still save money by opening a Good To Go account. Account holders can register their plate for the Pay By Plate option. Registered vehicles will pay an extra 25 cents for that option. Those vehicles with neither a pass nor a registered vehicle will pay an extra $2 per toll.

Tolls only apply to those passing through the 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.

According to WSDOT, the tolls are in place to pay for the $200 million construction bonds borrowed to build the SR 99 tunnel. That money is only a part of the $3.3 billion needed to replace the Alaskan Way Viaduct and rebuild SR 99 through Seattle.
