Repaving of State Route 518

July, 2015

WSDOT will repave westbound SR 518 from I-5 to 24th Ave S beginning in July. Work is scheduled to take place Monday through Thursday nights, typically from 8 p.m. to 6 a.m. There may also be single-lane closures on weekend nights. Drivers should prepare for some delays through the work zone. Please refer to the WSDOT project page here for more information.

Link Light Rail Extension

The South 200th Extension extends light rail from the current light rail station at
Sea-Tac Airport to South 200th Street in the City of SeaTac. The 1.6-mile elevated guideway and station will open in late 2016, at the same time as University Link and four years earlier than envisioned in the voter-approved Sound Transit 2 plan.
