Working to put together the details after this van rolled over on the ramp from southbound I-5 to westbound 526 this morning. A haz-mat response caused traffic to back up all the way into Everett. More details to come.
1:00pm Update: The truck was carrying welding tanks and one began leaking when it tipped over after getting into an accident with another vehicle. The ramps to westbound 526 and 527 were closed for about 2 hours. Firefighters were able to cap the leak and eliminate the hazard.
