There aren't many ways to get there from here. It's easy to underestimate the power of the Mississippi River until you realize that there are only four roads that cross Arkansas' eastern border. That's correct: four, for the entire state. Memphis holds two; the northern I-40 bridge and the southern I-55 bridge. Your next chance is a good bit farther south, in Helena, and your final opportunity lies at the southeastern corner of the state near Lake Chicot.
(We won't count the railroad-only bridge in Memphis, which technically makes five.)
