SEATTLE –Drivers accustomed to using State Route 520 overnight will need to plan ahead and budget extra time for their trips Thursday, Sept. 13. Construction crews will close both directions of SR 520 from 11 p.m. Thursday, Sept. 13, until 5 a.m. Friday, Sept. 14, from Montlake Boulevard in Seattle to I-405 in Bellevue.

During the closure, crews will remove overhead power and cable lines just west of the Bellevue Way overpass. The lines are being relocated to create space for cranes and other tall equipment that will be used to build the future westbound SR 520 off-ramp to Bellevue Way.

“We’re moving these lines to prevent workers and equipment from running into them during construction activities and to make sure power and cable service is uninterrupted while we widen SR 520,” said Brian Dobbins, construction manager for the Washington State Department of Transportation’s SR 520 Eastside Transit and HOV Project. “We need to close the road to move the necessary removal equipment into place and get those lines out of the way.”

SR 520 floating bridge maintenance crews will also take advantage of the closure to conduct inspection and repair work.

Two sections of SR 520 will remain open to traffic during the overnight closure: I-5 to Montlake Boulevard and areas east of I-405.

Weekend-long closure Sept. 21-24

The next weekend-long SR 520 closure is scheduled to begin at 11 p.m. Friday, Sept. 21, and last until 5 a.m. Monday, Sept. 24. The highway will close between Montlake Boulevard in Seattle and I-405 in Bellevue. Crews will use the closure to install another fish-friendly culvert beneath all lanes of SR 520 near 108th Avenue Northeast in Bellevue. All lanes of 108th Avenue Northeast, including the on-ramp to eastbound SR 520, will also close during the weekend between Northup Way and 112th Avenue Northeast.

To get between Seattle and the Eastside during the closures, drivers will need to take I-90 or find alternate routes around Lake Washington. Closure information and detour maps are online. Night work is planned, so residents near the work zone likely will 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 bus 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.
