Tolling the SR 99 Tunnel
Funding for the $3.1 billion viaduct replacement program comes from state, federal and local sources as well as the Port of Seattle and tolls on drivers using the tunnel. Of that total cost, the 2013 Legislature stated $200 million should come from toll funding. Tolls could also pay for future tunnel operations and maintenance costs, similar to other toll facilities in Washington.
Tolling the SR 99 tunnel is anticipated to begin in late 2015 when the tunnel opens to drivers.
Setting toll rates
The Washington State Transportation Commission will oversee the toll rate-setting process closer to when the tunnel opens in 2015.
Studying toll rates
In 2011, the city of Seattle and WSDOT formed the Advisory Committee on Tolling and Traffic Management to continue to look at various toll scenarios and how drivers may respond to different tunnel toll rates. The 15-member committee has studied toll scenarios with rates ranging from $0.50 to $4 per trip. Meetings are open to the public and meeting materials are available online. The committee anticipates providing advisory recommendations to the Governor, Legislature, State Transportation Commission, FHWA, WSDOT, Seattle Mayor and Seattle City Council in 2013.
Electronic toll collection
Tolls would be collected electronically; there would be no toll booths. For more information about WSDOT’s electronic toll collection system, visit the Good To Go! web page.
