Mexican Federal Highways are roads maintained and built by the federal government of Mexico, through the Secretariat of Communications and Transportation (in Spanish: Secretaría de Comunicaciones y Transportes, SCT). The Federal Highways in Mexico can be classified as high-speed roads with restricted access and low-speed roads with non-restricted access. Some Federal Highways charge a toll (cuota).

High speed with restricted-access roads[edit]

Restricted-access roads, known as Autopistas or Supercarreteras, are limited-access expressways with controlled points of access interchanges. Access to these roads is generally prohibited for pedestrians and animal-drawn vehicles, as fences are located at the side of the road for most of the length. Autopistas are divided highways with 4 or more lanes. Supercarreteras are always two-lane highways and are most commonly found in mountain areas. The maximum speed limit is 110 km/h (70 mph) for cars and 95 km/h (60 mph) for buses and trucks. In some cases, the maximum speed can be 120 km/h (75 mph).

Low speed with non-restricted-access roads[edit]

Low-speed/non-restricted-access roads, known as Autopistas or Carreteras, comprise the majority of the road network. Autopistas are divided highways with 4 or more lanes. Most of these Autopistas were single-carriageway roads converted into dual carriageway by building an adjacent road body next to the existing one. Carreteras are free and in most cases two-lane highways that cover almost all of Mexico. These roads have interchanges at major roads, but most intersections are at grade. The maximum speed limit is 100 km/h (60 mph) for cars and 95 km/h (60 mph) for buses and trucks.

Numbering system[edit]

North-south highways are assigned odd numbers, while east-west highway are identified by even numbers. The start of the numbering system is located in the northwest of the country.

Exceptions to the numbering system[edit]

There are two exceptions to the numbering system:

  1. Federal Highway 14 from Uruapan, Michoacán to Morelia, Michoacán, located in the midwest of the country.
  2. Federal Highway M-40, the New Mexico City orbital road.
