Mexican Federal Highway

Federal Highways (Spanish: Carreteras Federales) are a series of highways in Mexico. These highways link Mexico's 32 federal entities with each other or with a neighboring country, and they are wholly or mostly built by Mexico's federal government with federal funds or through federal grants by individuals, states, or municipalities. Locally known as federal highway corridors (Spanish: los corredores carreteros federales), they are built and maintained by Mexico's Secretariat of Infrastructure, Communications and Transportation (Spanish: Secretaría de Infraestructura, Comunicaciones y Transportes, SICT). Federal Highways in Mexico can be classified into high-speed, limited access expressways (usually toll highways that may be segmented and are marked by the letter "D") and low-speed roads with non-limited access; not all corridors are completely improved.
