Getting Back to the Main Road

You wandered into small side streets and need to find the main avenue again.

Perdón, ¿cómo hago para regresar a la avenida principal?

Sorry, how do I get back to the main avenue?
"Avenida principal" is universally understood. In some cities, locals may refer to it by its specific name instead.
Local
Tiene que devolverse para atrás por esta calle.
TYEH-neh keh deh-bohl-BEHR-seh PAH-rah ah-TRAHS por EHS-tah KAH-yeh.
You have to go back down this street.
"Devolverse" meaning to go back or retrace your steps is very common in Colombia and other Andean countries. In Mexico you'd more likely hear "regresarse."
You
¿Y luego? ¿Doblo a la derecha o a la izquierda?
ee LWEH-goh? DOH-bloh ah lah deh-REH-chah oh ah lah ees-KYEHR-dah?
And then? Do I turn right or left?
Local
Doble a la izquierda y va a ver la avenida principal enseguida.

Turn left and you'll see the main avenue right away.
