SEATTLE – While groundhogs are looking for signs of spring on Saturday, construction crews on State Route 520 will be looking to get as much work done as possible before Sunday morning.
Crews will close the highway between Montlake Boulevard and I-405 from 11 p.m. Friday, Feb. 1 to 5 a.m. Sunday, Feb. 3.
During the closure crews will install two overhead sign structures wide enough to accommodate the highway when it’s widened to six lanes.
Crews will also splice together new fiber optic lines to support the Washington State Department of Transportation’s Intelligent Transportation Systems. While crews are connecting the lines, much of the Seattle area traffic flow map will be off-line starting as soon as 8 p.m. Friday until early morning Saturday.
Crews are taking advantage of the full highway closure to tackle other critical work that can only happen while the road is closed.
Feb. 2 - 3 closure details
Crews will close both directions of SR 520 and all connected ramps between Montlake Boulevard in Seattle and Interstate 405 in Bellevue from 11 p.m. Friday, Feb. 1, to 5 a.m. Sunday, Feb. 3. Drivers will need to take I-90 or find alternate routes around Lake Washington. SR 520 will remain open between I-5 and Montlake Boulevard and east of I-405.
During previous SR 520 closures, the longest delays on I-90 occurred in the afternoon. To help keep traffic moving, WSDOT is adjusting the reversible I-90 express lanes schedule.
• Saturday, Feb. 2: I-90 express lanes will be open to westbound traffic from 7 a.m. to 2 p.m. Express lanes will open to eastbound traffic by 3 p.m.
Night work is planned, so residents near the work zone might hear construction noise.
SR 520 Eastside project overview
Crews working on the Eastside Transit and HOV Project are widening SR 520 to six lanes between Medina and Bellevue, rebuilding interchanges, constructing highway lids and transit stops in the center of the highway and installing fish-friendly culverts. In 2010, WSDOT awarded a $306 million design-build contract to Eastside Corridor Constructors, a joint venture of Granite Construction Company and PCL Construction Services. The completed Medina-to-Bellevue corridor is scheduled to open to traffic in December 2013.
