Overturned truck blocks all lanes of westbound Highway 18 at I-5
FEDERAL WAY – All westbound lanes of Highway 18 were closed at Weyerhauser on Thursday morning, as was the southbound exit to Interstate 5, as crews worked to clear a tanker truck that overturned at the interchange.
The Washington State Patrol said the truck driver suffered minor injuries.
Troopers advised using alternate routes as long backups were expected.
There was no immediate word on when the accident would be cleared.
