UPDATE: 7 a.m. | All lanes were reopened by 7 a.m.
All lanes of northbound I-5 between Arlington and Mount Vernon were closed for a time early this morning after a semi-truck flipped over, according to the State Patrol.
Traffic was being diverted to Old Highway 99 for a time, but once the FedEx truck was upright, traffic was able to move through on one lane.
The truck went on its side sometime around 5 a.m., according to Trooper Mark Francis.
The driver, who apparently fell asleep, suffered minor injuries. No other vehicles were involved in the crash.
