Mexico has an extensive network of roads including highways. Which of these roads have tolls and how high are they?
The Secretaría de Comunicaciones y Transportes website has a list of all toll-roads (Autopistas), their length, and toll charges. As mentioned in my comment, the toll is approximately $1-2MXN per kilometer of toll road between plazas.
The roads are designated with a
D, for example the free road from Tijuana to Ensenada is Route
1, the toll road from Tijuana to Ensenada is
1D. The distance from the toll plaza at Playas Tijuana and the plaza at Rosarito is 26km and the toll is $33 MXN.
