WDOT predicted a 40-45% dropoff in 520 traffic initially as tolls were introduced. They expect that as drivers evaluate their commute alternatives that about half of them will return to 520, according to a radio news report.

The toll is a good idea in regards to commuters. For years when thinking about methods to reduce traffic congestion and improve traffic flow I thought the state should impose a "dumb sh!t" tax on commuters who choose to live on one side of the lake and work on the other side. That makes no sense unless a person's life goals includes spending an extra 40 minutes a day sitting in stop and go traffic. The toll kinda' serves as that tax. It should be added to the I-90 bridge as well.
