  • Mississippi State Highway System

The Mississippi State Highway System is a network of roads that are maintained by the Mississippi Department of Transportation (MDOT). This network includes Interstate, U.S., and state highways.


In 1928, Mississippi Governor Theodore G. Bilbo appointed Horace Stansel head of a committee to investigate the state's highway needs. Stansel submitted an act to create a state highway system to the state legislature in 1930. Since then, Mississippi has gradually expanded its highway system.

Until 1987, there were but two major four-lane highways in Mississippi, not counting the Interstates, which were built during the 1960s and 1970s: U.S. Highway 49 (US 49) from Yazoo City to Gulfport and US 82 between Greenville and Winona. Things changed when the state legislature launched the $1.3 billion Four-Lane Highway Program of 1987.[1] This program gradually allowed for the funding of over 1,000 miles (1,600 km) of four-lane highway statewide. In 2002, the Four-Lane Highway Program was expanded in what was known as Vision 21.

MDOT was not created until 1992; this organization consolidated several services that already existed.
