Travelers should plan for multiple overnight ramp closures in Tukwila and SeaTac on Thursday night, July 18.
Contractor crews working for the Washington State Department of Transportation will re-stripe and set barrier on the southbound Interstate 5 ramp to northbound I-405, as well as repair pavement on the westbound State Route 518 ramps to southbound SR 99 and South 154th Street.
These weather-dependent closures are part of an ongoing rehabilitation project. Travelers should use signed detours or find alternate routes.

The following ramps will close from the evening of Thursday, July 18, to the morning of Friday, July 19:
• Westbound SR 518 to southbound SR 99 will close from 9 p.m. to 4:30 a.m.
