The State Patrol says a speeding Corvette going southbound crossed the median, went airborne, and smashed into an Isuzu Trooper and a minivan going northbound.

"When (the Corvette) came out of the median, it was pointed nose-down into the pavement and the back end was straight up," said State Patrol spokesman Lance Ramsey.

Two people in the Corvette were killed. The minivan carried a family of four -- two parents and two kids -- and the father was being airlifted to Harborview with critical injuries. The three others in the minivan had minor injuries as did the two people inside the Trooper.

The crash blocked two of the three northbound lanes in the area for several hours before being cleared around 5 p.m. The traffic backup stretched for 3-4 miles in both directions.

State troopers were running speed traps through the area during that time and the Corvette was one that got away from them.

"We're not going to get everybody," Ramsey said. "We're trying to get as many as we can that are driving excessive(ly fast) and out of control. We're not going to get everybody, and unfortunately, this is the one that we should have got."

The names of the victims have not been released.
