The Michigan Department of Transportation is responsible for addressing the movement of cargo by air, highway, marine, pipeline, and rail modes of transportation, including the interconnection of such modes. The functions needed to support this directive are maintained throughout the bureaus of Transportation Planning, Field Services, and Highway Development; the Office of Rail; the Office of Economic Development; and MDOT regions throughout the state.
An efficient and well-maintained transportation system serves as the backbone for all economic activity. Efficient transportation systems move goods and people throughout local, regional, state, national and international economies in a safe, timely and reliable manner. Michigan's freight transportation system is an important element of economic competitiveness, especially as the state continues to expand its role as a major domestic and global trade partner.
