Crews fought a brush fire north of Sumner on Sunday that caused backups for miles along northbound state Route 167.
The fire was reported about 4:15 p.m. near the Eighth Street East interchange. Firefighters closed the onramp from Eighth Street to SR 167 as they worked to put out the blaze.
About a half-mile of grass, brush and small trees burned, according to East Pierce Fire & Rescue.
No one was injured, and no buildings were threatened.
Central Pierce Fire & Rescue, Orting Valley Fire & Rescue, and Valley Regional Fire Authority also responded.
Crews expected to have the fire under control and reopen the exit about 6:30 p.m., and planned to stay into the night to put out remaining hot spots.
It appeared a discarded cigarette started the fire, Washington State Patrol spokesman Guy Gill said.
Valley Regional Fire Authority also reported a brush fire several miles further north Sunday at SR 167 and Ellingson Road, which they said was quickly contained.
