Interstate 5 commuters should expect delays Tuesday in both directions as fire crews remove hazardous trees south of Canyonville.

The Oregon Department of Transportation will slow traffic in both directions between mileposts 88 and 101 from 7 a.m. to 10 a.m., it said in a news release.

Oregon’s Milepost 97 fire is believed to have started Wednesday because of an illegal campfire. The nearly 12,000-acre fire is burning in rugged terrain near Canyonville, between Roseburg and Grants Pass. Fire officials said the fire continues to move south, parallel to I-5.

Firefighters are working alongside the southbound interstate, where the fire is burning down to the road, Oregon Department of Forestry spokesman Joe Touchstone said.

On Tuesday, flaggers will hold people entering the southbound side of the interstate up to 20 minutes at Exit 101 at Riddle Road, Exit 99 at North Canyonville and Exit 98 at Canyonville, the department said. Motorists going northbound will be held at Exit 88 at Azalea.

Southbound I-5 was already limited to a single lane from mileposts 97 to 93 due to the wildfire. Both off-ramps at Exit 95 at Canyon Creek are closed, and the transportation department said motorists in the area should expect congestion, delays and low visibility due to wildfire smoke.
