Dash cam video shows dump truck hopping concrete barrier onto I-405
New dash cam video sent to the Washington State Patrol is helping investigators map out the events that led to a dump truck hopping a concrete barrier and landing onto I-405 last week.
The crash happened Feb. 17 on northbound I-405 near 44th Street in Renton.
In the video, you can see the green dump truck speeding down a side road, launching itself over the barrier along I-405, scattering debris over the top of the vehicle with the camera.
The crash caused major delays on I-405 while crews cleaned up the debris. KIRO 7 reports several cars also crashed and two people sustained minor injuries.
