Semi Driver Dead In Crash On Interstate 5 Near Southcenter
A crash Monday afternoon sent a semi-truck over an embankment and left one person dead, according to WSP.

TUKWILA, WA — A semi-truck driver died Monday afternoon after a crash involving another vehicle on southbound Interstate 5, according to Washington State Patrol. Troopers asked drivers to avoid I-5 at the Interstate 405 interchange. Photos posted on social media showed the truck over an embankment, and officials said debris fully blocked the exit from eastbound State Route 518 to northbound I-405.
Hours later, southbound backups stretched for miles.
UPDATE: we have moved the collision south of I-405 so travelers can take north I-405 then south on SR167 as a detour option.
