SR 520 email update - July 10, 2014 

92nd Avenue Northeast reopens Friday
We’d like to thank drivers for their patience this week while 92nd Avenue Northeast is closed for roadway reconstruction just south of SR 520. Crews are nearly finished with their work there and are on track to reopen the street by 8 p.m. Friday, July 11.

Until then, a signed detour remains in place to help drivers navigate around the closure.

Driver alert: SR 520 full closure this weekend

Drivers, buckle up: SR 520 will be closed in both directions this weekend. Construction crews will close all lanes of SR 520 from Montlake Boulevard to I-405 from 11 p.m. Friday, July 11 to 5 a.m. Monday, July 14.

This closure, like a few others in recent weeks, will allow crews working on the SR 520 West Connection Bridge to continue pouring concrete for the new bridge deck on the west end of Lake Washington. Crews on the Eastside Project will also continue paving activities while the highway is closed. They plan to place up to 10,000 more tons of fresh asphalt for the new eastbound lanes of SR 520 east of the floating bridge. Come Monday morning, all the mainline lanes of SR 520 between Medina and 108th Avenue Northeast, in both directions, will be fully paved – layered 12 inches deep in smooth asphalt.

Crews will also close 108th Avenue Northeast / 112th Avenue Northeast underneath SR 520 for paving

We appreciate drivers’ patience and cooperation in leaving extra time for trips, taking transit, and using alternate routes as we conduct this critical work during the summer construction season. We know road closures are an inconvenience, but each one is allowing our crews to get a significant amount of work done more quickly and safely. And in the end, that means we’ll finish our highway improvements and be out of drivers’ way sooner.

New Eastside transit stop and direct-access ramps open on Monday morning

Transit riders on the Eastside will see a new configuration along SR 520 starting Monday morning when the new 92nd Avenue Northeast median transit stop opens to riders.

The new stop features elevators, a covered waiting area and other amenities, however it will not be ADA-accessible until the contractor receives a final elevator permit in the coming days. The temporary transit shuttle service between Evergreen Point Road and 92nd Avenue Northeast will be discontinued Monday when the new 92nd Avenue Northeast stop opens to riders.

Crews on Monday will also open new direct-access ramps for buses at 108th Avenue Northeast to serve the busy South Kirkland Park and Ride. These ramps will be open only to buses until the highway’s new HOV lanes open later this year. When that happens, the ramps will open to carpools, too.

Get ready for major week-long I-90 closure in July

One of the biggest highway construction closures of the summer is scheduled to begin in mid-July when westbound I-90 near Mercer Island is reduced to just one lane around-the-clock for seven days. During the closure, contractor crews will replace two 33-year-old, 92-foot-long expansion joints on the East Channel Bridge just west of I-405.

Contractor crews will need seven days to replace these joints due to their size, and the fact that the joints are deeply embedded into the concrete bridge deck.

The lane closures will affect a lot of people, particularly during the morning and evening commutes, so travelers are encouraged to start planning now to avoid getting caught in a big backup.

I-90 lane-closure details

  • At 9:30 p.m. on Friday, July 18, contractor crews will close all but one lane of westbound I-90 just before Bellevue Way Southeast to replace the two expansion joints on the East Channel Bridge. The work will be split into two stages over the course of the seven-day lane closure.
  • WSDOT has created animated traffic maps to illustrate the lane closures and how traffic will flow during the work. Read more…

Visit the SR 520 outreach booth at Redmond Derby Days this Saturday!

Come chat with our staff at the 2014 Redmond Derby Days summer celebration. WSDOT will be hosting a booth all about the SR 520 program, where you can learn the latest about current construction on the Eastside, our work on the new floating bridge on Lake Washington, and what’s next for the corridor in Seattle. Our staff will be available to answer your questions and provide handouts and printed materials. We hope to see you there!
