TRANSPORTATION COMMISSION
[Filed May 20, 2025, 8:38 a.m., effective July 1, 2025]
Effective Date of Rule: July 1, 2025.

This rule will implement the planned three percent toll rate increase for the SR 99 tunnel that will take effect on July 1, 2025, as established in WAC 468-270-073 and as described in WAC 468-270-040.
