The Washington State Department of Transportation (WSDOT) warns that an upcoming closure from June 17 to 20 has the potential to cause gridlock throughout the region.
The closure, which will involve both directions of 520 traffic between I-405 and Montlake Boulevard, will begin at 11 p.m. on Friday, June 17, and continue until 5 a.m. on Monday, June 20. Approximately 166,000 vehicles travel across the 520 bridge on a typical summer weekend, according to WSDOT.
During the closure, crews will construct new fish passage culverts under the bridge, remove a pedestrian bridge in preparation for future projects, install a new barrier, and perform routine maintenance such as re-striping and pothole filling.
WSDOT asks that drivers avoid discretionary trips during the closure, carpool and use transit. The agency plans for six additional weekend 520 closures through the end of the year, with the next closure planned for a weekend in July.
