Advisory Committee on Tolling and Traffic Management

Advisory Committee on Tolling and Traffic Management (2011 - present)

WSDOT and the City of Seattle established an advisory committee on tolling in fall 2011. The committee is exploring ways to refine tolling of the SR 99 tunnel to minimize traffic diversion and meet funding goals, and investigate strategies to reduce or mitigate diversion. The committee will submit its initial recommendations in 2013 to the Governor, Legislature, State Transportation Commission, WSDOT, Seattle Mayor and the Seattle City Council.

The committee will finalize its recommendations in December 2015, when the tunnel is scheduled to open and tolling begins. It will continue work for up to one year after tolling begins to evaluate its effect on city street and I-5 traffic.

WSDOT, the Seattle Mayor and Seattle City Council jointly appointed the 15 committee members (pdf 29 kb). Five members were nominated by each, and membership was confirmed by the City Council. Members were selected to represent various interests, including freight, retail, drivers, labor, bicycle and pedestrian interests, large employers, waterfront businesses, adjacent and affected neighborhoods, transit riders and low income people.

Meetings are open to the public. For questions about the committee, please contact the program office at viaduct@wsdot.wa.gov.

The ACTT prepared a progress report to share their work through 2012 and discuss policy issues. This report, and accompanying letter, were distributed by the committee’s co-chairs to a variety of agencies and appointed and elected officials in December 2012. The committee is halfway through its analysis of potential toll scenarios, and anticipates providing recommendations in mid-2013.
