One person has died after a sewage tanker overturned on State Route 702 at State Route 507 near the Thurston/Pierce County line.

All southbound SR 507 lanes were closed for a couple of hours due to the collision but have since reopened.

Washington State Trooper Guy Gill tweeted the driver of the tanker was heading westbound on SR 702 near SR 507. He ran the intersection into a parking lot and rolled the tanker.

The collision killed the male driver of the truck and spilled about 3,000 gallons of landfill waste water onto the road.

There was reportedly heavy fog in the area at the time of the collision, said Gill.

Crews cleared the wreckage and waste off the road and SR 507 reopened around 12:15 p.m.
