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.
