The Transportation Commission is designated in law as the State Tolling Authority and sets toll rates and policies for all state highways and bridges.
Tolling is an innovative tool for easing congestion and for funding and maintaining major transportation projects. Washington currently has five tolled facilities: the SR 16 Tacoma Narrows Bridge, SR 167 HOT Lanes, SR 520 bridge, the I-405 express toll Lanes, and the SR 99 tunnel.
NEW: 2022 Tacoma Narrows Bridge Rate Reduction
The Washington State Legislature passed legislation (SB 5488) in 2022 that provided funding and directed the Washington State Transportation Commission to adjust toll rates on the Tacoma Narrow Bridge (TNB). Based upon this direction and the funding amount provided, the Commission took action in August 2022, to reduce TNB toll rates with an effective date of October 1, 2022. You can learn more about the rate reduction here.
2023 Tolling Report
The Commission released its 2023 Tolling report (pdf 6mb) which summarizes toll-related activities for the past year, and expected toll-related activities for the year ahead.
The 2023 Tolling Report also includes the 2023 Tacoma Narrows Bridge Loan Update. As directed by the Legislature, the annual loan update includes sufficient information to enable the Legislature to determine an adequate amount to loan the Tacoma Narrows Bridge (TNB) Account each biennium, without requiring higher than planned rate increases or changes to the debt service plan repayment schedule.

SR 99 Tunnel Toll Rates and Policies
In October 2018 the Transportation Commission adopted toll rates for the SR 99 tunnel. The SR 99 tunnel opened in February 2019, and tolling began on Saturday, November 9, 2019. Toll rates vary by time of day and are collected in both directions. Tolling on the SR 99 tunnel is expected to raise revenues to fund $200 million of construction costs, and to fund ongoing operations and maintenance. Tolling also helps manage congestion on the SR 99 corridor, particularly with tolls varying by time of day.

I-405 & SR 167 Express Toll Lanes Toll Rates and Policies
The I-405 express toll lanes (ETLs) between Lynnwood and Bellevue opened in September 2015. The ETLs project converted an existing high occupancy vehicle (HOV) lane to an ETL with dynamic tolling, and added a second ETL in each direction between SR 522 and downtown Bellevue.
In “dynamic tolling” projects, the Transportation Commission sets minimum and maximum toll rates, and then tolls vary automatically depending on traffic volumes and speeds. Toll rates are displayed on overhead electronic signs.
For more information visit the WSDOT I-405 Express Toll Lanes page.
SR 520 Bridge Toll Rates and Policies
Tolling started December 29, 2011 on the SR 520 bridge. The SR 520 bridge uses all-electronic tolling, meaning that there are no toll booths. Toll rates vary by time of day and are collected in both directions. Tolling on the SR 520 bridge is intended to generate revenues necessary to fund $1.2 billion of the construction costs for the new bridge that opened in April 2016, and to fund ongoing operations and maintenance. In addition, tolling helps manage congestion on the SR 520 corridor, particularly with tolls varying by time of day.

SR 16 Tacoma Narrows Bridge Toll Rates and Policies
The new eastbound Tacoma Narrows Bridge opened with tolling in July 2007. Rates on the Tacoma Narrows Bridge are fixed and do not vary by time of day or day of week. Tolling on the Tacoma Narrows Bridge is intended to generate revenues necessary to fund construction costs for the eastbound bridge, and to fund ongoing operations and maintenance. Tolling is scheduled to sunset with repayment of all financial obligations by about June 2032. In addition, tolling helps manage congestion on the SR 16 corridor.

Toll Exemptions for All Tolled Facilities
The Transportation Commission sets exemptions for tolled facilities. On Tuesday, July 17, 2018, after input from the public and stakeholders, the Transportation Commission adopted changes to some tolling exemptions and fees so they are consistent across all of the state’s tolled facilities. These tolling exemptions took effect on August 1, 2019.
These changes simplify use of all tolled facilities, reduce administrative efforts with streamlined regulations, support parity between communities with tolled facilities, and further align tolling policies with state transportation system goals. None of these changes are expected to result in the need for a toll rate increase.

The Commission has completed several toll-related studies over the years. Most recently, the Commission was directed in the 2019/21 Transportation Budget to conduct a study to assess possible approaches to offering toll discounts to low-income drivers on the I-405/SR 167 Express Toll Lane (ETL) system. For access to the various reports, please refer to the Other Tolling Reports and Studies section on our Studies, Reports and Surveys page.
