What bridges are the trash trucks crossing?
The full trash trucks cross into Michigan on the Blue Water Bridge in Port Huron. Of those 350 trucks, a large majority of trucks return via the Ambassador Bridge in Detroit. The Blue Water Bridge charges trucks by axle and the Ambassador Bridge charges by weight, so it is cheaper for the empty trucks to return via the Ambassador Bridge. There are also smaller quantities of trash coming across the Soo International Bridge in Sault Ste Marie.
