SALEM, Ore. (KOIN) — Heavy rain across the region flooded many local streets Thursday and caused landslides that blocked traffic on major highways for hours.
Friday morning, flooding was still an issue. Fern Hill Road in Washington County flooded and caused road closures.
In Woodland, all lanes of I-5 NB north of Dike Road were blocked after a landslide left debris piled on the roadway shortly after 4 p.m. By 9 p.m., 2 lanes were back open.
“Any time we have a slide adjacent to one of the major routes it’s a concern, especially when there’s traffic on the highway,” Bart Treece with WSDOT told KOIN 6 News.
Treece said landslides have been happening in areas that aren’t usually trouble spots.
“There are some signs that tip us off to potential trouble,” he said. “It might be dirty water in the ditch that wasn’t there, some rocks in the ditch that weren’t there the day before.”
Crews will assess the hillside where the I-5 NB landslide happened Friday morning.
Sheriff’s deputies also reported a pothole blocking southbound lanes of I-5 not far from the landslide north of Dike Road.
WSDOT tried to patch the pothole, but with the wet conditions, it wouldn’t hold up. Officials said at least one southbound lane would remain closed until the rain stopped and they could properly patch it.
One westbound lane of W Burnside Street near NW Hermosa Boulevard was also blocked due to a landslide during the Thursday evening commute.
In Washington County, high water caused flooding on Scholls Ferry Road at Clark Hill. SW 149th Avenue and Division Street was also flooded from Johnson Creek.
