Federal Highway 30 (Spanish: Carretera Federal 30, Fed. 30) is a free part of the federal highways corridors (Spanish: los corredores carreteros federales).[2] The highway starts in Torreón at Fed. 40 in the southwest and winds across the central Mexican Plateau, following a roughly northeasterly direction. The highway eventually ends to the northeast in Monclova, Coahuila at Fed. 57.[3] The total length of Fed. 30 is 351.0 km (218.1 mi).
The main Fed. 30 trunk runs from Torreón to Monclova at a length of 332.3 km (206.5 mi). At San Pedro de las Colonias, an additional 18.7 km (11.6 mi) spur reconnects Fed. 30 with Fed. 40 in La Cuchilla, Coahuila.
