  • Louisiana State Highway System

TheInterstate Highway System in Louisiana consists of 933.84 miles (1,502.87 km)[4] offreeways constructed and maintained by theLouisiana Department of Transportation and Development (La DOTD).

The system was authorized on June 29, 1956 whenPresidentDwight D. Eisenhower signed into law theFederal Aid Highway Act of 1956.[1] The Louisiana Department of Highways, predecessor of the DOTD, began construction shortly afterward on its portion of the system, to which approximately 686 miles (1,104 km) was initially allotted.[5] The first road segment in the new system was officially opened and dedicated on February 24, 1960 and consisted of a portion of thePontchartrain Expressway (I-10) inNew Orleans.[2] Two months later, the first Interstate Highway shields installed in Louisiana accompanied the opening of a portion ofI-20 nearRuston on April 23.[3]
