Five weeks of overnight SR 520 bridge closures start Jan. 10

Late-night commuters be forewarned. Late-night closures of the State Route 520 floating bridge are planned during the next five weeks as crews install equipment above the lanes for electronic tolling. Drivers need to plan ahead for detours across and around Lake Washington starting Monday, Jan. 10. Crews plan to close all eastbound lanes from Montlake Boulevard in Seattle to 92nd Avenue NE in Medina overnight Jan. 10-14. The bridge closes at 11:59 p.m. each night and reopens by 4 a.m. the following morning.

“This work is a major step to prepare for tolling the SR 520 floating bridge this spring,” said Craig Stone, WSDOT Toll Division Director. “Installing the equipment now allows us time to thoroughly test the toll collection system before we start tolling traffic to pay for a much-needed replacement bridge.”

During the closures, crews will install conduit, Good to Go! pass readers, photo tolling equipment and overhead electronic toll rate signs on and near the east highrise of the bridge.

Work and overnight closures continue into February, alternating between the eastbound and westbound lanes as crews shift their work zones. There also will be three weekends of overnight closures on Friday and Saturday nights beginning the weekend of Jan. 21-22. Those weekend closures begin at 11:59 p.m. and crews will reopen lanes by 7 a.m. on Saturdays and 7:30 a.m. on Sundays.

Drivers should plan to take alternate routes such as I-90, I-405, I-5 and SR 522. Updated closure information and links are on the project website.

Traffic closure details Where: Eastbound or westbound SR 520 from Montlake Boulevard E. in Seattle to 92nd Avenue NE in Medina. SR 520 will remain open from I-5 to Montlake Boulevard E. and east of the 92nd Avenue NE exit.

What should drivers do?

About tolling on SR 520 In spring 2011, all-electronic tolling will begin on the floating section of the SR 520 Bridge to help pay for the construction of a new safer bridge opening by the end of 2014. This use of technology to collect tolls will keep traffic moving on SR 520 with no tollbooths, no stopping and no slowing down. Tolls will be collected in two ways: as vehicles drive under an electronic sensor, the toll will be automatically deducted from a prepaid account. Or, if the driver does not have a prepaid account, a photo will be taken of the vehicle’s license plate and a bill will be sent to the registered owner in the mail.
