A mudslide and downed tree closed a portion of Northwest Bridge Avenue, which takes Portland-bound drivers from the St. Johns Bridge to U.S. 30, around 6 p.m. Tuesday.



One lane of eastbound U.S. 30 near the ramp was also closed to Portland-bound traffic, according to Damon Simmons, a Portland Fire & Rescue spokesman.



Don Hamilton, a spokesman for the Oregon Department of Transportation, said crews were working to remove 100 yards of debris from the ramp and the roadway. They planned to continue Wednesday morning.



"It's really hard to clean up at night," he said. "This is not a small slide."



Hamilton said crews were working to set up signs redirecting motorists to an alternate off-ramp of the bridge.
