Highway 520 Bridge will be closed between Seattle and Bellevue this weekend as construction to widen the highway and add lidded overpasses on the Eastside continues. The bridge will close at 11 p.m. on Friday, April 27, and reopen on Monday morning at 5 a.m.
All lanes will be closed between Montlake Boulevard in Seattle and Interstate 405 in Bellevue, as construction workers install 42 concrete girders and 1,000 feet of drainage pipes beneath the highway.
Commuters should expect delays on Interstate 90, I-405 and I-5 during heavier travel times midday Saturday and Sunday, according to the Washington State Department of Transportation.
Express lanes on Interstate 90 will open westbound from 6 a.m. to 2 p.m. and eastbound after 3 p.m. both days this weekend. The highway between I-5 and Montlake and east of Bellevue will remain open.
