Firefighters respond to smoke near Ross Island Bridge
PORTLAND, Ore. - Visible smoke on the east end of the Ross Island Bridge was causing drivers to slow down Thursday morning.
Portland Fire and Rescue said a brush fire on the bank of the Willamette River caused the smoke.
Two fire engines responded and made quick progress on the fire.
Officials say the fire is burning in a difficult location with a steep embankment. It's about 10 to 12 feet deep in blackberry brambles, which, when they burn, produce a lot of black smoke.
An investigator is working to determine how the fire started.
