Eastbound Interstate 90 was blocked Monday afternoon after an RV crashed and exploded into heavy flames.
At about 12:20 p.m., an RV was seen on the WSDOT traffic cameras in the Mount Baker tunnel after it had crashed into the median.
According to the Washington State Patrol, a car was also involved in the collision.
The camera showed flames coming from the front of the vehicle as a person stepped outside. They appeared to be shaken up.
At one point it appeared the vehicle exploded, causing the WSDOT cameras to go black momentarily.
Once the camera came back, the RV was completely engulfed in flames.
There were no reported injuries.
The roadway was finally reopened just after 7 p.m. following inspections.
