Wash. State Patrol photo shows the crash scene.

TUKWILA, Wash. - A semi truck overturned and crashed Thursday morning at a major freeway interchange under Interstate 5 in Tukwila, dumping a load of PVC pipes across the highway and creating an hours-long traffic nightmare.

A preliminary investigation found that the semi rig was traveling well over the speed limit when it rolled, the Washington State Patrol reported.

State Department of Transportation cameras showed a huge mess at the scene, with pipes and debris scattered as the roadway and a rolled-over semi tractor-trailer rig.

State troopers and medics responded to the scene, on the eastbound State Route 518 ramp to northbound I-405 and the southbound I-5 ramp to northbound I-405, at about 11 a.m. after receiving reports of a serious crash.

Johnson said the semi truck was heading south on I-5 and took the ramp to northbound I-405, where it ended up rolling over onto its side and crashing. The semi driver was checked out by medics and found to be uninjured.

It took until just after 2:30 to clear the damage and get the freeway reopened.

According to witnesses, the semi was traveling at about 55 mph when it entered the curve, where the speed limit is 35 mph. Johnson said the driver will be cited for negligent driving and will receive a big bill for the cost of cleaning up the mess and towing away the tractor and trailer.
