Working for the Weekend

If you’re planning on going across Lake Washington this weekend, it looks like I-90 might be your best bet. Crews will close the SR 520 bridge between Montlake Boulevard and I-405 from 11 p.m. Friday until 5 a.m. Monday. During the closure, the eastbound lanes will shift to the south between Evergreen Point Road and 92nd Avenue Northeast. Work includes installing bridge lighting at 84th Avenue Northeast, drainage culverts and pavement for the new roadway across the Evergreen Point Road lidded overpass. The work is weather dependent, and if it’s rained out you can find the latest on the SR 520 Bridge Weekend Closure page.
