FEDERAL WAY, Wash. - A sticky situation on Interstate 5 clogged the freeway for hours after a semitruck dumped 20,000 gallons of a glue-like substance on I-5 north of Federal Way.
Four lanes of northbound I-5 were shut down just north of Highway 18 Wednesday night after a semitruck slammed into a stalled minivan that was stopped on I-5 shortly before 7 p.m.
The driver of the minivan, a 55-year-old Federal Way woman, was seriously injured and transported to Harborview. The 61-year-old driver of the semitruck was not hurt.
The substance the truck was hauling spread all over I-5, creating a gooey and slippery mess.
Accident investigators worked for hours to piece together the crash. When they were finished, Department of Ecology workers and a private contractor were set to start the cleanup of the nontoxic, water soluble substance.
Troopers said it was a resin used in manufacturing.
The resin was hauled in bladders on the flatbed of the semi. During the crash, one of the bladders broke, leaking about 20,000 gallons of the glue.
To get the mess off of I-5, workers pressure washed the roadway and then used vacuums to suck up the water. Officials worked through the night to get it cleaned up.
By 7 a.m. Thursday morning, only one lane remained closed as workers continued to spread sand and clear the scene.
