I wonder why we keep investing [[wasting?) money on highway infrastructure to accommodate more trucks when clearly railroads are a much more efficient method of moving large quantities of freight. The Gordie Howe Bridge and the widening of I-94 are costing zillions of dollars when a single additional railroad tunnel added to the one downtown and in Port Huron would seem to be much more cost effective. I'm guessing there are some transit experts here that have some answers to this.
