Repairs needed on damaged stormwater pipe underneath highway

SEATTLE – State Route 520’s westbound on-ramp at 84th Avenue Northeast near Bellevue will close to traffic, starting tonight, so crews can repair a damaged stormwater pipe beneath the highway. The ramp closure, which begins at 11 p.m., will last until repairs are completed – likely one to two weeks, according to the Washington State Department of Transportation.

During the closure, motorists will need to use the Bellevue Way on-ramp, about two miles to the east, to access SR 520’s westbound lanes. Detour signs will direct traffic to the Bellevue Way on-ramp.

A contractor working on WSDOT’s SR 520 Bridge Replacement and HOV Program inadvertently drilled into the buried 30-inch stormwater pipe about 10 days ago while preparing to install the foundation for a new sign bridge that will span the highway. Over the next week or more, the contractor will excavate around the damaged pipe, make repairs, then backfill the repair area (pdf 412 KB). Repairs will be made at contractor expense.

Residents near the work area may hear construction equipment during these repairs. The contractor will work to minimize noise as much as possible while completing the repairs needed to reopen the on-ramp.

The Eastside segment of WSDOT’s SR 520 reconstruction program involves widening the highway to six lanes between Medina and I-405, rebuilding interchanges, constructing highway lids and in-median bus stops, and installing fish-friendly culverts. The completed Eastside corridor is expected to open to traffic in late summer 2014.
