Transportation Infrastructure

For more than 100 years, the Detroit region’s well-connected transportation infrastructure has served the automotive industry’s supply chain and is positioned to become the next transportation logistics hub. With a vastly integrated highway and freeway system, seven international border crossings, five major airports, several airfields, four public transportation authorities, a deep-water marine port and eight rail yards, people and goods move easily throughout the region, United States, and North America.
