List of state highways in Alabama

The State Route System in Alabama uses the standard numbering convention: odd numbers signify a north-south state route, and even numbers signify an east-west route. Often more than one route number shares the same roadway, so identifying which route the mile markers are for is often difficult. In no case does a State Route number mirror a U.S. Highway number. As such, the following State Routes do not exist: 11, 29, 31, 43, 45, 72, 78, 80, 82, 84, 90, 98, 231, 278, 280, 331, 411 or 431.
