Gov. Gretchen Whitmer has said that the Detroit-Windsor area is the “busiest active border crossing in North America,” and that about $200 billion of trade flows between the two countries annually. 

A border that is active has plenty of infrastructure that needs to be maintained. Regine Beauboeuf, CEO of the Detroit-Windsor Tunnel for American Roads, oversees the bridges, tunnels and toll roads that exist between the two countries. 

She joined The Metro live from Mackinac Island on Wednesday to discuss what her job entails and to provide more insight on the consequences of the trade war between the U.S and Canada. 

American Roads is a U.S.-based owner and operator of transportation infrastructure, including toll assets, and currently operates three toll bridges — including the international tunnel connecting Detroit with Windsor.

She spoke about the region's unique cross-border economy and why she doesn't expect to see a major impact at the border from Trump's recent tariffs.

"Together Detroit and Windsor, really that's its own ecosystem," she said. "We've been working together; it's not just trade, it's also people [who] will come to work, like the health care workers who are coming here; you have people with families or in-laws in other countries...so there is a very strong history between Windsor and Detroit and I don't think you'll see that being affected."
