520 Closures Slated for the Next Two Weekends

If you're planning to head to the city for a game, take note of closures, including on State route 520, on Sept. 6-7 and 13-15.

Late-summer construction and improvements on three local highways – State Route 520, Interstate 5, and State Route 99 – will require several roadway closures and driver patience during the weekends of Sept. 6-7 and Sept. 13-16, the WSDOT says. 

The 520 bridge will be closed in the westbound direction between 92nd Avenue NE and Montlake Blvd. from Friday, Sept. 6 at 11 p.m. until 5p.m. Saturday, Sept. 7. The following weekend, the bridge will close in both directions between Interstate 405 and Montlake Blvd. from 11 p.m. Friday to 9 a.m. Sunday, Sept. 15.

Following is a press release from the Washington State Department of Transportation and Seattle Department of Transportation (SDOT):

“Coordinating the closures for this busy summer construction season was like piecing together a jigsaw puzzle,” said WSDOT traffic engineer Mark Bandy. “We really appreciate drivers’ continued patience with us as we put the last couple of pieces down and wrap things up in time for winter.”
