America's Freight Transportation Gateways

Transportation gatewaysseaports, airports, and land border crossingsare the entry and exit points for international merchandise trade between the United States and countries around the world. During the past decade, the leading U.S. gateways handled increasing volumes of freight as the movement of merchandise trade to and from our nation rose. Some facilities increased in relative importance, while others declined. Changes in freight movement influenced investment needs for air and marine facilities, land border crossings, and connecting infrastructure linking gateways to commercial and population centers.
