MARYSVILLE — A high-speed rollover crash temporarily closed I-5 in both directions Saturday, but left no serious injuries, the Washington State Patrol reported.

Troopers said they were investigating the driver for two counts of vehicular assault.

All four occupants were listed in good condition Saturday at Providence Regional Medical Center Everett.

It happened around 1 a.m., as a man in his early 20s was driving south in a mid-1990s BMW, troopers said. He lost control, overcorrected and hit the median barrier near milepost 198, on the south end of Marysville.

Riding in the car were two other men and a woman, all in their late teens to early 20s, troopers said.
