Mississippi State Highways
The Mississippi State Highway System consists of 86 state highways that are not part of the Interstate Highway System or the United States Numbered Highway System. These highways are maintained by the Mississippi Department of Transportation (MDOT) and provide a network of roads for travel within the state.
The state highways are numbered from 1 to 76, with the exception of MS 20, which was renumbered to I-20 in the 1960s. Most three-digit numbered routes are numbered by region, with the 300s in the northernmost part of the state, the 600s in the southernmost part, and the 700s and 900s being used for short connectors and spurs.
The state highways in Mississippi range in length from a few miles to over 100 miles. Some of the most important state highways include MS 1, MS 4, MS 5, MS 25, and MS 72.
The state highways in Mississippi are an important part of the state’s transportation system. They provide a network of roads for travel within the state, and they also connect Mississippi to other states and regions.
