DUFUR, Ore. (AP) - An Oregon state highway is shut down as firefighters try to contain a wildfire burning southeast of The Dalles that has again doubled in size, jumping across the Deschutes River.

The Central Oregon Interagency Dispatch Center said on Twitter Saturday that Highway 216 is closed for the fire response to keep the public safe.

It has now burned 52 square miles (135 square kilometers) and has grown to an estimated fire size of 33,408 acres.

The flames on Friday crossed the Deschutes River to the east bank near Jones Canyon.

Firefighters using an air tanker dropped retardant over the wildfire area and warned drivers nearby of possible visibility problems.

The Wasco County Sheriff's Office said on Facebook that residents along the river from Sherars Falls to Mack's Canyon should evacuate.

The fire was started Thursday by farm machinery.Copyright 2018 The Associated Press. All rights reserved. This material may not be published, broadcast, rewritten or redistributed.
