The Mississippi Department of Transportation (MDOT) is responsible for the establishment and classification of a system of state-maintained highways, which includes interstate highways, U.S. highways, and state highways.

[edit] History

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: 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 of four lane highway statewide. In 2002, the Four Lane Highway Program was expanded in what was known as Vision 21.

The Mississippi Department of Transportation was not created until 1992; this organization consolidated several services that already existed.
