The crash was reported about 9:45 a.m., said trooper Mark Francis with the Washington State Patrol.
A smaller vehicle apparently cut off a 16,000-pound converted bread truck, he said.
The truck flipped over and leaked a small amount of chemicals. Local hazardous material teams responded to help with cleanup.
Exits to Highways 526 and 527 were blocked for some time, according to transportation officials.
