The state Transportation Department is preparing to start tolling on the Highway 520 floating bridge between Seattle and Bellevue.
The department said Tuesday that drivers can now open Good To Go accounts for electronic tolling. There will be no toll booths on the bridge. Drivers without accounts will get a higher bill in the mail.
The revenue will help pay for construction of a new floating bridge on Lake Washington.
Electronic tolling already is in use on the Tacoma Narrows Bridge. Cars with transponders are scanned, and the toll is automatically deducted from prepaid accounts.
