| General description: | ||||||
| Federal highways: Odd numbers generally denote north-south routes, while even numbers
denote east-west routes. Numbers increase in eastbound and southbound direction respectively.
Motorways have the suffix D. They are usually parallel to the old road with the same number, e.g. MEX180D is parallel to MEX180. Exit numbers are sequential (only on some roads).
Since the shape of Mexico is not much like a rectangle, the grid is not very straight MEX1 is the main north-south route on the Baja California peninsula. MEX15 Nogales-Mexico is an east-west route roughly between Guadalajara and Mexico. Other main north-south routes are MEX45 Ciudad Juaréz-Mexico, MEX57 Piedras Negras-Mexico and MEX95 Mexico-Acapulco. MEX180 is the main coast road along the Gulf of Mexico, between Matamoros and Cancún. MEX200 runs along the Pacific coast between Tepic and Guatemala. | ||||||
