Check out the latest pontoon construction progress in Aberdeen
Crews have been hard at work in Aberdeen on the second cycle of six new pontoons to support the new SR 520 floating bridge. We’ve posted recent photos of work on the new pontoons as they take shape, including pouring concrete for the top slabs.
Stay tuned to the latest pontoon and floating bridge information and photos online.
Final reminder: SR 520 weekend closure this weekend Feb. 1-3
Get ready for the next weekend closure of SR 520 scheduled from 11 p.m. Friday, Feb. 1 to 5 a.m. Sunday, Feb. 3. Please note that the re-opening time on Sunday has been revised. The highway will open by 5 a.m., rather than noon as previously stated, giving drivers more time to travel across the lake Sunday morning.
During the closure crews working on the SR 520 Eastside project will work to shift fiber optic lines that are critical for the region’s highway cameras and traffic information systems. We’ll also install new sign structures that are part of the highway’s driver information system. Crews need to complete the work before they’re able to shift traffic onto a newly widened section of the highway later this year.
SR 520 will be closed from Montlake Boulevard in Seattle to I-405 in Bellevue. Drivers are encouraged to find alternate routes or take transit during the closure.
Join us next week: Feb. 5 and 6 SR 520 open houses in Bellevue and Seattle
Come learn more in Bellevue and Seattle next week when we share the latest information and answer your questions about SR 520 construction and design progress. We’ll preview upcoming construction activities and share tools to help you prepare for roadway closures and night work before they happen.
We’ll also have information about the next phase of construction that will begin in summer 2014: building the north half of the new west approach bridge. This new structure will connect the new floating bridge to the Montlake Boulevard interchange in Seattle. Learn what the new west approach bridge will look like, how you’ll walk, bike, bus or drive across the lake, and how we plan to build it.
