The Washington State Transportation Commission (WSTC) is conducting public engagement processes related to two future toll policy and rate-setting determinations. One concerns SR 509 and SR 167 expressway tolling (which is referred to collectively as the Puget Sound Gateway Program). The other involves SR 99 Tunnel toll rates.
Puget Sound Gateway: An initial, one-mile segment of the SR 509 Expressway will see tolling begin this October. More tolled segments here and on SR 167 will open in stages from 2026 to 2030. Proposed options for variable toll rates “to support traffic management in the corridor and to meet financial requirements” are detailed on WSTC’s Gateway Program toll rate setting page.
Public engagement from late March to early April is planned as an online open house and two virtual meetings. WSTC is due to choose its final proposal later in April, and it will hold a final hearing in June.
SR 99 Tunnel: A scheduled three-year, three-percent rate increase for the SR 99 Tunnel is coming up on July 1. A virtual meeting on the resulting rates is scheduled for May 13-14. Further information can be obtained and comments can be submitted electronically via a WSTC toll rates and policies page.
