Driving and finding places
Streets are laid out on a grid system
Avenidas
Avenidas (avenues) run parallel to the length of the island "north - south"
Avenida Rafael E. Melgar, or "el Malecón", runs along the waterfront
Avenidas are numbered by 5's (5a, 10a, 15a, etc.) counting away from Av. Melgar
Most are one-way in alternating directions
Large Avenidas that are divided are two-way
Some large divided Avenidas have "special" names instead of numbers:
Avenida Pedro Joaquin Coldwell = 30a Avenida
Avenida 8 de Octubre = 65a Avenida
Avenidas have few stops, and some will get you from one end of town to the other nonstop
Calles
Calles (streets) run across the island "east - west"
Calles are numbered with odd numbers counting south from Av. Benito Juárez
Calles are numbered with even numbers counting north from Av. Benito Juárez
Calle Dr. Adolfo Rosado Salas is between Calle 1 Sur and Calle 3 Sur
Most are one-way in alternating directions
The large divided Calles are two-way
Some large Calles have "special" names instead of numbers (and are called Avenidas!):
Avenida Andrés Quintana Roo = Calle 11 Sur
Avenida Xel-Ha = Calle 15 Sur
Most calles have stop signs at every cross street
Avenida Benito Juárez, the Transversal highway
Divides "Norte" from "Sur"
Referred to as Avenida Benito Juárez "in town"
Referred to as Carretera Transversal outside of town
One-way from Melgar to Coldwell (30), two-way east of there
Carretera Costera Sur
Southern Coastal Highway
What Avenida Rafael E. Melgar becomes south of town
Carretera San Juan
San Juan (Northern Coastal) Highway
What Avenida Rafael E. Melgar becomes north of town
North and South
Streets are specified as being Norte (Nte) if they're north of Avenida Benito Juárez
Streets are specified as being Sur if they're south of Avenida Benito Juárez
Bis and C
Bis mean repeated, and these streets fall between other numbers
Bis C streets exist in some places to make up for a further lack of street numbers
For example, there's 15a Avenida Sur, 15a Avenida Bis Sur, and 15a Avenida Bis C Sur
"Funky" Streets
Here and there, seemingly at random, named streets appear between the numbered ones or the regular numbering system isn't followed
In some areas the alternation of one-way directions isn't followed, especially around parks and schools
Google Maps typically shows these correctly (or nearly so)
Addresses follow conventions different from north of the border
Street numbers are inconsistent and are often not used even when they are assigned
Quite a few places officially have no number at all - s/n means "sin número", or "without a number"
Addresses are often specified as being on a street between two others or at the corner of another one
con = with or at, entre = between, esquina = (at the) corner (of), frente = across from
Correct addresses always include the Colonia (neighborhood)
Parking
Red-painted curbs mean "No Parking" and tickets are likely
A sign on a post or painted on the road showing an E in a slashed circle also marks "No Parking"
"No Estacionarse" painted on a wall or gate denotes a private entry where you should not park
"Se Usará Grúa" means "Tow-away Zone" (literally "the crane will be used"). They mean it.
"Se Ponchan Llantas Gratis" means "Tires Punctured for Free". Don't block driveways!
Even if not marked, don't block people's or businesses' driveways
A parking violation will result in removal of your license plate to ensure you pay up
On the waterfront, wheel-locking boots are applied with enthusiasm
Public parking lots (Estacionamiento Público) are plentiful and cheap
Parking lots typically cost 10-15 pesos an hour
Parking lots do close at night, so be sure you know when to return for your car - the last ferry arrives after nearby parking lots are closed for the night!
