At least three people were killed and more than 70 injured after an Amtrak train derailed near Tacoma, Washington, early Monday morning.

A train car was left dangling over an overpass on I-5 - which has been shut down - in DuPont. The train reportedly struck something on the tracks. 

Jonathan Hunt reported on "Happening Now" that the Cascades train line was on its inaugural route out of a new station in Tacoma. 

He said a "ribbon-cutting" ceremony just happened on Friday. 

The train, which was traveling at approximately 80 miles per hour, was carrying more than 80 passengers, according to officials.

Police previously said several vehicles were struck by the derailed train cars, injuring multiple drivers on the highway.

At least 77 people have been taken to hospitals for treatment.

The southbound lanes of I-5, which see about 60,000 vehicles per day, are expected to be closed for "an extended period," according to the Washington State Department of Transportation.
