Update 11:45 a.m.; All lanes of I-405 have re-opened.



A crash involving a semi and at least two vehicles has closed Interstate 405 southbound near Everett Street. One northbound lane is also blocked by an ambulance. Crews have closed the ramp from U.S. 30 westbound onto I-405 as well.

Southbound traffic is being diverted to the Glisan offramp. Drivers should use Interstate 5 southbound during the clean up. Traditionally, moving a jack-knifed semi after a crash takes time and special equipment. Expect I-405 to be closed for an extended period.

Notably, there is also a crash blocking a lane of I-5 northbound near the Morrison Bridge. This crash should clear shortly, but is causing delays on I-5 south of downtown.
