Driving through the north end of the SR 99 Tunnel.

Toll rates for the State Route 99 tunnel in Seattle are set to go up by 3% beginning July 1, the Washington State Transportation Commission announced Friday.

The 3% increase means an increase of five to 10 cents for vehicles with two axles, depending on the time of day. Drivers with a Good To Go! pass will continue paying the lowest toll rate.

The weekday peak rate for Good to Go! drivers of $2.60 will increase to $2.70, and the weekday Pay By Mail rate of $4.60 will increase to $4.70.
