Smoother ride ahead for SR 520 between Bellevue and Redmond

The following is a release from the Washington State Department of Transportation:

Nearly three miles of State Route 520 between Bellevue and Redmond will get a facelift this summer.

Starting the evening of Monday, July 7 contractor crews from Granite Construction Company will begin nightly lane and ramp closures to grind and repave sections of SR 520 between 108th Avenue Northeast in Bellevue and West Lake Sammamish Parkway in Redmond.

Crews will pave the following areas of SR 520:

  • Eastbound lanes from 108th Avenue Northeast to 124th Avenue Northeast
  • Westbound lanes from 116th Avenue Northeast to 108th Avenue Northeast
  • Westbound lanes from West Lake Sammamish Parkway to Northeast 51st Street.

The crews from Granite will also repave 10 ramps, including most of the SR 520/I-405 interchange.

“These areas were last paved 15 to 20 years ago,” said WSDOT project engineer Mark Sawyer. “With more than 100,000 vehicles each day using SR 520 each day, the pavement is rutted and cracked. Repaving it adds many more years to the highway’s lifespan as we continue to improve the corridor for drivers.”

The work will involve grinding off the top two inches of the existing pavement to remove cracks and ruts, repairing areas where the subgrade has deteriorated and repaving the highway with new asphalt. Crews will also replace expansion joints on four bridges, perform bridge deck repair, and install high visibility striping.

To complete the work, the crews will close up to two lanes at a time on SR 520. Lanes may close as early as 8 p.m. Saturday through Thursday with all lanes open by 5 a.m. on weekdays and 10 a.m. on weekends. Ramps may close beginning at 9 p.m. and reopen by 5 a.m. on weekdays and 6 a.m. on weekends.

Work on this project is scheduled to be complete in fall 2014. Information on lane closures will be updated regularly in the King County construction update report.
