Certain hazmat restrictions to be lifted on Ambassador Bridge in Detroit

The Michigan Department of Transportation (MDOT) will lift some hazardous materials restrictions on the Ambassador Bridge in Detroit next month.

Effective October 29, 2024, MDOT will allow the transport of some fuels and materials for batteries over the Ambassador Bridge linking Porter Street in Detroit to Canada.

The Detroit International Bridge Co. (DIBC) requested the modifications to current restrictions placed on what types of materials are allowed to cross the Ambassador Bridge. 

Officials say that the decision to allow certain types of hazardous material transport on the Ambassador Bridge comes after review of public comments and meetings with law enforcement and first responders. The agency collected more than 80 letters from elected officials, business owners and other members of the public, many expressing support for the changed restrictions.

“DIBC currently has a fire suppression system and spill mitigation protocols and materials in place. Restricted materials will only be transported during off-peak hours, under the supervision of vehicle escorts,” MDOT said.
