How are the tolls determined and adjusted?

In determining toll amounts, the transportation commission considers data and information provided by the department of transportation, public opinion and advice from any required citizen advisory committee.
(1) Tacoma Narrows Bridge. In accordance with chapter 47.46 RCW, the commission must consider the toll rate advice of the citizen advisory committee and must set toll amounts that cover the debt and operations and maintenance until the indebtedness is repaid as required by law.
(2) SR 520 Bridge. The commission must consider toll rates that will help maintain travel time, speed, and reliability on the corridor and must set and adjust toll rates to generate revenue sufficient and necessary to cover costs and obligations described in RCW 47.56.830 and 47.56.850.
(3) SR 99 Tunnel.
(a) The commission must consider toll rates that will help maintain travel time, speed, and reliability on the tunnel and must set and adjust toll rates to generate revenue sufficient and necessary to cover costs and obligations described in RCW 47.56.830 and 47.56.850.
(b) Effective July 1, 2022, and every three years thereafter, subject to review and potential adjustment by the commission, toll rates shall be set as follows:
(i) All two-axle Good To Go!™ toll rates shall increase by three percent, rounded to the nearest five cent interval.
(ii) All two-axle Pay By Mail toll rates shall be set to two dollars more than the revised two-axle Good To Go!™ toll rates.
(iii) All multi-axle Good To Go!™ and Pay By Mail toll rates shall be set equal to one-half the revised two-axle rates, multiplied by the number of axles up to a maximum of six axles, and rounded to the nearest five cent interval.
(4) I-405 express toll lanes.
(a) The commission must consider a schedule of toll rates that will maintain travel time, speed, and reliability on the corridor as described in RCW 47.56.850 and 47.56.880. The schedule adopted by the commission will allow toll rates to vary in amount by time of day, level of traffic congestion within the highway facility, and other criteria.
(b) The commission must set a minimum and a maximum toll rate, each subject to review on an annual basis or as needed to maintain performance requirements outlined in RCW 47.56.880.
(c) The commission must set an additional fixed amount to be added to the toll rate for vehicles that are not registered for a Good To Go!™ account who pay the Pay By Mail toll rate.
