A tractor-trailer lost control and rolled over Thursday on state Route 512 in the Puyallup/Sumner area.
The state Department of Transportation said the eastbound SR 512 offramp to southbound state Route 167 was closed for three hours. Traffic was detoured to northbound SR167.
The accident occurred about 12:20 p.m. at milepost 12, and the Washington state Department of Transportation reported the ramp reopened about 3:30 p.m.
It was not immediately clear what caused the semi to topple over or whether the driver was injured.
WSDOT urged drivers to avoid the area.
