Mount Vernon, WA: Dump truck plows head-on into stalled I-5 traffic on Saturday, July 18th 2015

A double-dump truck heading south on Interstate 5 near Mount Vernon plowed across the median Saturday morning and into northbound traffic that was already nearly stalled for an investigation of a fatal early morning shooting on the freeway.Six people were taken to Skagit Valley Hospital, with two later airlifted in critical condition to Harborview Medical Center in Seattle. One other was taken to PeaceHealth United General Medical Center, said Washington State Patrol Trooper Mark Francis.
At least 23 vehicles were involved, including the truck, which was full of a clay and gravel mixture, Francis said.The driver, who was among the six taken to Skagit Valley Hospital, had chest injuries and a broken arm. Francis said it is possible a medical condition was a factor in the 8:30 a.m. crash.Both directions of I-5 were closed, and caused miles of backups throughout the afternoon. At one point, Washington State Department of Transportation (WSDOT) reported drivers going the wrong way up and down I-5 ramps and warned drivers not to, because it puts everyone in danger.By 2 p.m., WSDOT had opened one lane of southbound I-5. By 6:30 p.m., all lanes were open.At the time of the crash, northbound traffic was being diverted to Anderson Road at exit 225 because of the earlier shooting, which the Washington State Patrol said was a drive-by.Troopers were called to the area near the College Way exit 227 in Mount Vernon where they found two men in their 20s, the driver and front-seat passenger, dead inside a vehicle just after 3 a.m.
