The maximum tolls on Interstate 405 (I-405) and State Route 167 (SR 167) went up to $15 earlier this year, but it’s likely that rate will be going up again next year.
Washington’s tolling system is going through a massive growth spurt, and there are going to be significant changes over the next year. The state is currently widening I-405 between Bellevue and Renton and updating the tolling equipment on SR 167.
Once completed late next year or sometime in 2026, there will be a complete tolling corridor that stretches from Lynnwood to Puyallup.

In order to make that happen, the state needs to standardize the tolling system. Right now, there are different rules for I-405 and SR 167 regarding peak hours, carpool requirements and other issues.
“For it to work properly and smoothly and to really achieve more operational efficiency, we need to have one set of rules, one set of policies that governs that entire corridor,” Reema Griffith, the Executive Director of the Washington State Transportation Commission (WSTC), said. Her agency is tasked with standardizing the rules and setting the requirements.
