Cross Border Traffic Study

In response to industry and border stakeholder concerns that the existing Ontario – Michigan crossings would not support the anticipated increase in traffic, a study to collect origin-destination patterns of cross-border trips, was carried out in 2000 by the Ontario Ministry of Transportation, Transport Canada, the Michigan Department of Transportation and the U.S. Federal Highway Administration.

The study included over 22,000 traveller surveys at four separate border crossings: the Ambassador Bridge, Windsor-Detroit Tunnel, Blue Water Bridge and the Sault Ste. Marie International Bridge. This survey information supported the development of baseline information for the subsequent Planning Need and Feasibility Study and, ultimately, the creation of the Canada-U.S.-Ontario-Michigan Border Transportation Partnership. The study was published in August 2001.
