Before Trailer Bridge was established, shippers couldn t use the same type of service to over-water destinations that was commonplace for them on land. Trailer Bridge changed this by adapting what works best on water with what works best on the highway to link the two together to drive down costs. The company s Trailer Bridge system is a network that provides true single-carrier responsibility. Its founder, Malcom P. McLean, who invented containerization more than 40 years ago, created its combination of over-the road and over-the-water transportation. The company provides trucking and marine freight service to and from all points in the lower 48 states and Puerto Rico, bringing efficiency, environmental and safety benefits to domestic cargo in that traffic lane. This total transportation system utilizes its own trucks, drivers, trailers, containers and U.S. flag vessels to link the mainland with Puerto Rico via marine facilities in Jacksonville, Fla., and San Juan. Trailer Bridge is located in Jacksonville, Fla.
