Traffic on the Ambassador Bridge was backed up briefly coming into Detroit Thursday evening. That’s because protesters targeting bridge owner Matty Moroun blocked traffic.

The demonstrators included a State Representative, members of the ongoing Occupy Detroit movement, union members and southwest Detroit residents. They’re all angry at Ambassador Bridge owner Matty Moroun—who they say has illegally seized land, ignored court orders, and bought political influence in Lansing and elsewhere.

Detroit resident Maya Williamson said the neighborhood is noisy and polluted because bridge traffic is forced onto residential streets—and she’s tired of it.

“The noise, and the traffic through the school area and through the neighborhoods…it’s horrendous. There’s gotta be a stop put to it, you know. You can’t just trample over citizens for money,"said Williamson.

No protesters were arrested. They left after about an hour, chanting “We’ll be back.”
