The Secretariat of Infrastructure, Communications and Transportation (Secretaría de Infraestructura, Comunicaciones y Transportes, SICT) of Mexico is the national federal entity that regulates commercial road traffic and broadcasting. Its headquarters are in the Torre Libertad on Reforma in Mexico City but some aspects of the department still function at the old headquarters located at the intersection of Eje Central and Eje 4 Sur (Xola). The building is decorated with murals created by arranging small colored stones on the building's outer walls.
The forerunner of the modern-day SCT was created in 1891 under President Porfirio Díaz and was known as the Secretariat of Communications (Secretaría de Comunicaciones); its first incumbent as secretary was Manuel González Cosío. In 1920 it was renamed to the Secretariat of Communications and Public Works (Secretaría de Comunicaciones y Obras Públicas; "SCOP"). In 1959, it changed names to Secretariat of Communications and Transportation, and finally, in 2019, it added Infrastructure to its name, to encompass and highlight one of its sub-organs, the Subsecretaría de Infraestructura..
The SCT is headed by the Secretary of Communications and Transport, a member of the federal executive cabinet. Under the 1917 Constitution, this position has been held by the following individuals:
The Direction General of Civil Aeronautics is the agency under the SCT that regulates aviation.[2]
The Rail Transportation Regulatory Agency (ARTF) is the agency under the SCT that regulates railroads."
