The Jefferson Highway was an automobile highway that stretched through the central United States from New Orleans, Louisiana, to Winnipeg, Manitoba, Canada. Built in the 1910s as part of the National Auto Trail System and named for President Thomas Jefferson, it was inspired by the east-west Lincoln Highway and was nicknamed the "Palm to Pine Highway" for the differing trees found at either end. It was replaced by the new numbered US Highway system in the late 1920s, but portions of the route are still named Jefferson Highway, including stretches in Jefferson Parish and East Baton Rouge Parish, Louisiana, Lee's Summit, Missouri, Osseo, Minnesota, and Wadena, Minnesota.
