Fire crews said a hazmat situation that prompted the evacuation of everyone 300 feet around a Southfield hotel Wednesday was caused by fumes from a box of hair dye.

DETROIT – On Monday, Local 4 News went one on one with Ambassador Bridge officials to talk about whether they should be allowed to transport hazardous materials over the international crossing. The state confirmed to Local 4 a request has been made from the Ambassador Bridge to allow hazmat to cross over it. But at the same time the Michigan Department of Transportation says they asked for certain information from the Ambassador Bridge company months ago and still have not received anything. Typically, the Ambassador Bridge company doesn’t do many interviews. The bridge company has many letters of endorsement including one from they Wayne County Sheriff.

DETROIT The owners of the 91-year-old suspension bridge across the Detroit River asked the Michigan Department of Transportation to allow trucks carrying flammable, chemical or corrosive materials to cross the bridge. An estimated 10,000 trucks cross the Ambassador Bridge every day and bridge owners are pushing for a change to allow trucks carrying Class 3 Flammable liquids and HAZMAT Class 8 Corrosive substances to be transported over the 4-lane bridge. We dont need to be adding potential hazardous material slips onto the bridge or into the river, Chang said. His ferry is allowed to transport trucks carrying hazardous materials and admits this change would affect his business. Meantime, the Wayne County Commission unanimously voted to urge Michigan officials to block the bridge from allowing the HAZMAT to be transported.
