Mexico road map

Main federal highways

How the numbering works

Federal routes follow a scheme little changed since the 1930s. Odd numbers run north–south, even numbers east–west, and the lower the number the older and more important the road: MX-1 is the Baja Transpeninsular, MX-2 traces the border, MX-15 is the Pacific spine. Three-digit numbers are secondary federal or state roads that feed the main corridors — MX-307 down the Quintana Roo coast, MX-175 over the mountains from Oaxaca City to the sea. A D after the number marks the tolled version, de cuota.

Where a D road exists, the plain number survives next to it as the libre, the free road. It shadows the motorway, often within sight of it, and drops into every village on the way. Junctions are signed CUOTA and LIBRE. Mexico has about 10,000 km of toll motorway and 50,000 km of free federal road.

Casetas, the TAG and what a toll is worth

Tolls are collected at casetas, plazas set across the carriageway rather than at the exits, so a driver pays for a section however little is used. The bill is substantial: on a long corridor tolls come to about as much as fuel. Intercity buses pay it without exception: first-class operators fold the toll into the fare, and a bus from Mexico City to Querétaro keeps its timetable because it never leaves the motorway.

Cash in pesos works everywhere; card acceptance is patchy and foreign cards often refused, so regular drivers carry a TAG, the prepaid windscreen transponder issued by CAPUFE, successor to the IAVE tag, and by TeleVía and PASE. Keep the printed ticket: the fare includes traveller's insurance covering medical costs and vehicle damage on that stretch, and the receipt is the proof of cover.

Driving distances from Mexico City

The four long corridors

MX-15D is the Pacific run: from the crossing at Nogales, across the Sonoran desert to Hermosillo and Guaymas, down into the irrigated valleys of Sinaloa at Los Mochis and Culiacán, to the sea at Mazatlán, then inland through Tepic to Guadalajara, some 2,300 km.

MX-57D, the NAFTA highway, runs from Piedras Negras in Coahuila south through Saltillo and San Luis Potosí into the Bajío, past the vehicle and aerospace plants of León and Querétaro, and into the Valley of Mexico. It carries more freight than any other road in the country.

The Gulf road, MX-180, follows the coast from Matamoros in Tamaulipas through Tampico, Veracruz, Coatzacoalcos and Villahermosa before crossing the Yucatán Peninsula to Mérida and Cancún. It is flat, hot and slow where it threads towns in Veracruz and Tabasco, fast on the tolled Mérida–Cancún section.

MX-1 is the exception to everything above: 1,711 km from Tijuana through Ensenada, Loreto and La Paz to Cabo San Lucas, with no parallel route: two lanes, little or no hard shoulder for hundreds of kilometres, fuel stops far apart, and when it closes there is nothing to divert onto. At Guerrero Negro it crosses into Baja California Sur and a different time zone.

Newer roads across the mountains

The Mazatlán–Durango motorway (MX-40D), opened in 2013, carries about 230 km of divided road over the Sierra Madre Occidental on 61 tunnels and more than 100 bridges, replacing the two-lane Espinazo del Diablo. Its centrepiece, the Baluarte Bicentenario, is a cable-stayed span whose deck sits roughly 400 m above the river, the highest of its type in the world when it opened. The drive from Durango to Mazatlán fell from six hours or more to about three.

The Barranca Larga–Ventanilla highway, opened in February 2024, did the same for Oaxaca: about 100 km of new road from Oaxaca City over the Sierra Madre del Sur to the coast near Puerto Escondido, cutting a winding six- or seven-hour drive on MX-175 to about three and a half.

What surprises US drivers

On libre roads the pace is set by topes — speed bumps, sometimes a metre wide and rarely painted, at the entrance and exit of every settlement. They are why a free road takes half again as long as its toll twin. Junctions are the other surprise: Mexican motorways generally allow no left turn off the carriageway. Traffic exits right onto a lateral, the frontage road alongside, and turns back through a retorno, a U-turn slot. Missing an exit means driving on to the next retorno.

Fuel is sold by the litre, not the gallon, and stations are attended; there is no self-service. Ask for Magna (87 octane, green pump) or Premium (around 92, red pump); diesel is sold at the same stations. A small tip for the attendant is normal. Pemex is the largest brand but franchise chains now share the forecourts; carry cash outside the cities.

The Ángeles Verdes, the Green Angels, are a federal fleet of green pickup trucks patrolling the highways since 1960 with bilingual crews. They give free labour, mechanical help, first aid and radio assistance, charging only for parts, fuel and oil. Dial 078; 911 is the general emergency number. Drive by day: most incidents on rural roads happen after dark, and unfenced stretches mean cattle, horses and dogs on the carriageway at night. The north, Tamaulipas in particular, carries travel advisories — check them before planning a route through the border region.

Questions about driving in Mexico

What is the difference between cuota and libre roads?

Cuota highways are tolled, divided, fenced and patrolled, and are the roads to use for long distances. Libre roads are free, two-lane and pass through every town with speed bumps (topes). Tolls are paid in cash or with a TAG (IAVE/TeleVía) transponder.

How much do tolls cost in Mexico?

Enough to matter: on a long corridor the casetas can cost about as much as the fuel, and the Autopista del Sol from Mexico City to Acapulco is among the most expensive per kilometre in the country. CAPUFE and the state concessionaires publish the tariff for every plaza. Pesos in cash always work; foreign cards are often refused.

Can I drive from the US into Mexico?

Yes. You need a Temporary Import Permit (TIP) for the car beyond the border zone (about 25 km, or all of Baja and most of Sonora, which are exempt), Mexican liability insurance (US policies are not valid) and an FMM tourist permit for stays over 72 hours.

How long does it take to drive across Mexico?

Tijuana to Cancún is about 4,500 km on the highway network, roughly 55 hours of driving over six or seven days. Mexico City to Cancún is 1,600 km, about 18 hours.

Is it safe to drive at night in Mexico?

The standard advice, including from the US State Department, is to use toll roads and to travel by day. Rural roads carry unlit vehicles, cattle and unmarked topes after dark, and most incidents happen at night. Check the current advisory for each state on your route.
