Three paving projects will start rolling in south King County in July

The Washington State Department of Transportation announced on Tuesday (June 30) that three state highways in south King County are about to undergo “much-needed work to repair and preserve the roadways,” beginning in July.

Starting Monday, July 6, contractor crews working for the WSDOT will kick off projects to replace 8 miles of worn and damaged pavement on state routes 509, 518 and 164.

“These highways were last paved almost two decades ago,” said WSDOT Engineering Manager Cathy Arnold. “Repaving them will extend their lifespans, prevent additional damage and reduce annual maintenance costs.”

Details for each project:

SR 518 between the I-5/I-405 interchange and 24th Avenue South near Sea-Tac Airport

  • Tucci & Sons will also repave more than 2 miles of westbound SR 518 along with 11 on- and off-ramps.
  • Work is scheduled to begin Monday, July 6.
  • Drivers should plan for overnight lane and ramp closures.

SR 509 between Burien and Normandy Park

  • Contractor Tucci & Sons will repave a half-mile of SR 509/First Avenue South between South Normandy Road and South 174th Street.
  • Work will begin in mid-July.
  • Drivers should plan for nighttime closures of multiple lanes.

SR 164 between Auburn and Enumclaw

  • On Monday, July 6, contractor crews from ICON Materials will begin work on a $3.9 million project to repave 5.5 miles between Hemlock Street Southeast and Southeast 408th Street . Crews will also upgrade three pedestrian crossings.
  • This work requires daytime and nighttime lane closures during off-peak commuting hours, but drivers should still plan for delays.
  • In the event of a concert at the White River Amphitheatre that will attract more than 3,000 people, there will be no construction closures.

These are three of eight pavement-preservation projects on area highways this summer. Work on these projects is scheduled to be complete this fall.
