Update, 8:55 p.m. Aug. 20:

Springfield neo-Nazi Jimmy Marr, known for his public displays of racism and anti-Semitism, appeared to take credit for the banners Sunday on social media.

A family driving north from California to see Monday's solar eclipse from Oregon found hatred on the freeway Saturday morning after they entered the northwestern state.

Beth and Michael Dershowitz and their kids saw the first banner south of Eugene. It said: "UNJEW HUMANITY."

They felt shaken, Dershowitz wrote in an email.

Then they saw three more just south of Salem, facing south on an I-5 overpass. Two of them read "Eclipse Whitey" and "Jewish Financing Available."

Michael Dershowitz wanted to confront the men behind the banners, his wife wrote, but he didn't because she feared for her children's safety.

The father took a photo instead.

"I cannot believe that we still have to face this vicious anti-Semitism in such a public place in 2017," Beth Dershowitz told The Oregonian/OregonLive in an email. "We want to expose this hatred so people stop pretending like it isn't happening in our own backyards."

The Oregon Department of Transportation responded to calls about the signs but they had been removed as of 2 p.m. Saturday, said Angela Beers Seydel, a spokeswoman for the agency.

The state's transportation department does not allow signs or "people calling attention to themselves" on overpasses, regardless of content, Beers Seydel said in an email. The agency's policy is to remove the signs.

"The distraction is dangerous to drivers and we do see crashes occur when these situations happen," Beers Seydel said.

She said transportation officials received reports of signs on I-5 south yesterday, but the signs had also been removed before state crews got there.

Saturdays incident was at least the second time someone has hung Anti-Semitic signs from freeway overpasses in Oregon.

Portland also had to remove signs from a freeway overpass in June.
