Updated at 12:30 p.m. with number of injuries.
Seattle commuters heading south from Lynnwood experienced significant delays Friday morning after a seven-vehicle crash blocked all lanes except the far right lane just before 8:30 a.m. The involved vehicles were moved to the shoulder about 30 minutes later, and the freeway was completely reopened after that.
One driver suffered minor injuries and was transported to Swedish Edmonds. Lynnwood Fire spokeswoman Julie Moore said other drivers also suffered minor injuries, but they did not require transport.
The cause of the crash is unclear.
