J&M Tank Lines, Inc. started in 1948 when the company founder, Jimmie McClinton, took out a loan of $125 from the People’s Bank in Selma, AL, moved his one truck from Selma to Montgomery, AL and put the legacy of J&M Tank Lines, Inc. into motion. Until the mid-1960s, baled cotton was the main commodity transported by J&M Trucking. The company eventually became the largest hauler of baled cotton in the United States.
In 1952, McClinton brought three partners into the business—Buck Jackson, Wingate Jackson, and Bill Jackson—and the trucking company grew steadily. Harold A Sumerford Sr joined the operation in 1961 as bookkeeper and assistant manager, and in 1966 McClinton and Sumerford bought out the other partners. Through the 1960’s J&M Trucking had grown its increasingly diversified operation to over 700 company-owned tractors and was posting roughly $40 million in annual gross revenues. The operation included flatbed, van, and tank trailers.
Liquid and dry bulk carriers activity had grown enough by 1979 that the tank division of J&M Transportation was established. J&M Tank Lines was officially launched in 1980 and began operating with 60 trucks. In 1995, J&M Tank Lines established a new division hauling liquid food grade commodities throughout the United States. Today, J&M Tank Lines operates approximately 450 tractors, 550 pneumatic dry bulk carriers, 50 tank trailers, a handful of flatbeds and vans dispersed among 15 terminals. Regional hauls averaging 178 miles fleet-wide predominate, and most operations are conducted in the eastern half of the United States, with a primary focus on the Southeast and Gulf Coast.
