The U.S. Supreme Court has turned down an appeal in a lawsuit that challenges the selection of a Detroit neighborhood for a new bridge to Canada.
Neighborhood groups and the private owners of the Ambassador Bridge claim the federal government violated environmental law, among other legal standards. But the work of the Federal Highway Administration has been upheld by a federal judge and an appeals court.
The Supreme Court said today it won't get involved.
Supporters of a second bridge between Detroit and Ontario, Canada, say it could open by 2020. Canada and the federal government recently announced a critical deal to build a toll plaza on the U.S. side.
