Regulations say hazardous materials can not be carried over the Ambassador Bridge. The Michigan Transportation Department has reviewed the law and has determined it will stay in place. So things that are radioactive, flammable or explosive are not allowed to be hauled over by vehicles. It's being reported those who own the bridge may take the case to court.

The Ambassador Bridge connects Detroit and Windsor. Construction started in August, 1927 and it opened in November, 1929. It's about 1.3 miles long and it took nearly 21,000 tons of steel to build. At its highest point it's about 152 feet above the Detroit River.
