Mobility is one of the most important characteristics of economic activity within a region. As the northern entry point of the NAFTA corridor, St. Clair County makes moving goods, materials and people easy. With multi-modal assets supporting travel by highway, water, air and rail, St. Clair County provides quick and easy access to larger markets in the U.S. and Canada as well as to key suppliers in the automotive, alternative energy and defense industries.

St. Clair County's location & outstanding transportation network make the area especially attractive to companies that need easy access to major markets, but would like to do without the congestion of a large metropolitan area.  The I-69 corridor and CN line link directly to deep water ports in Canada: Port Ruppert on the west coast, and Port Halifax on the east coast.

A St. Clair County location provides value to companies that ship or receive goods along the I-69 NAFTA corridor, including the following:

  • A central location in North America for distribution to and from international markets
  • Quick connections to/from Canada  via the Blue Water Bridge. The Blue Water Bridge is far less congested than the Ambassador Bridge in Detroit and connects with two major highways.  
  • The CN railroad crosses under the river through a double-stacked tunnel, allowing more freight to cross the border at once.
  • Freighters travel through the St. Clair River and Lake Huron, the midpoint of the St. Lawrence Seaway system. Deep water ports along the shoreline, including one in Marysville, can accommodate Great Lakes and ocean-going freighters.
  • St. Clair County offers an international private/cargo airport complete with U.S. Customs services and also close proximity to two nearby major airports (Flint’s Bishop Airport and Detroit Metro Airport).
  • Close proximity to the world’s largest automotive cluster and supply chain, as well as the southwest Ontario and Michigan food belt
