Washington may hike tolls to $18 as highway costs spiral out of control

Toll charges on two major Washington highways could soon rise to $18. The proposed increase aims to cover soaring construction costs and a projected shortfall in funding. Officials are now reviewing options after toll revenue grew by over 30% last year but still fell short of expectations. Interstate 405 and State Route 167 brought in $30.4 million from tolls in 2024, with around 6,400 weekday trips on average. Total toll revenue climbed to $39.9 million, a 31.2% jump from the previous year. Despite this growth, an analysis by the state treasurer’s office warned of a potential $10 million shortfall.

Highway construction costs have surged by 70% since 2020, putting pressure on planned projects. A proposed toll hike to $18 would only cover part of the $450 million gap needed for upcoming work. Transportation consultants noted that the increase would impact just a small portion of drivers. Rep. Andrew Barkis suggested alternative solutions, including cutting regulatory delays and redirecting funds from the Climate Commitment Act. Meanwhile, Washington remains the eighth-most regulated state in the US, according to a recent study. The Washington State Department of Transportation (WSDOT) plans to gather more data in the coming months before making a final recommendation to the commission.

The decision on toll increases will depend on further analysis and policy adjustments. WSDOT will present updated figures to help officials weigh the options. Even with higher tolls, a significant funding gap remains for future highway projects.
