DetroitâWindsor Truck Ferry Information
The service is split between two companies, Detroit-Windsor Truck Ferry, Incorporated of Detroit and CMT Canadian Maritime Transport, Limited of Windsor. 
It currently accepts only trucks. The ferry is the primary crossing for hazardous materials (HAZMAT) trucks between Windsor and La Salle in Ontario, and Detroit and the Downriver communities in Michigan, although other transport trucks may use it as a time-saving alternative to the bridges. Hazardous materials have been banned from the Ambassador Bridge and DetroitâWindsor Tunnel. The nearest alternative crossing that allows hazardous or radioactive materials is the Bluewater Bridge, which connects Port Huron, Michigan, and Sarnia, Ontario. 
Similar to all the international crossings in the DetroitâWindsor area, a toll is required, as is clearance from Canada Border Services Agency and the U.S. Customs and Border Protection at both terminals of the ferry route.
On the Detroit side of the river, the truck ferry entrance is at 1475 Springwells Court; that street intersects West Jefferson Avenue between South Schroeder Street and South Post Street. The dock is at the mouth of the River Rouge across from Zug Island.
Customs offices are at the entrances, and one must make a clearance with Customs before embarking onto the truck ferry, for standard procedures.
