Confirming You're Going the Right Way

You've been walking a while and stop to ask if you're headed in the right direction.

You
Disculpe, ¿voy bien para el mercado central?
dees-KOOL-peh, voy bee-EHN PAH-rah el mehr-KAH-doh sehn-TRAHL?
Excuse me, am I going the right way to the central market?
'¿Voy bien para...?' is an extremely useful phrase. It literally means 'Am I going well toward...?' and is the most natural way to confirm your direction.
Local
Sí, siga derecho. Ya casi llega.
see, SEE-gah deh-REH-choh. yah KAH-see YEH-gah.
Yes, keep going straight. You're almost there.
'Siga derecho' means 'keep going straight.' 'Ya casi llega' means 'you're almost there' — very reassuring to hear!
You
¿Está cerca? Es que llevo rato caminando.
ehs-TAH SEHR-kah? ehs keh YEH-voh RRAH-toh kah-mee-NAHN-doh.
Is it close? I've been walking for a while.
'Llevo rato caminando' means 'I've been walking for a while.' 'Llevar + time + gerund' is the Spanish way to express duration of an ongoing action.
Local
Sí, está muy cerca. Son como dos cuadras más. No tiene que regresar.
see, ehs-TAH mooy SEHR-kah. sohn KOH-moh dohs KWAH-drahs mahs. noh tee-EH-neh keh rreh-greh-SAR.
Yes, it's very close. It's about two more blocks. You don't have to go back.
'No tiene que regresar' means 'you don't have to go back.' 'Cuadras' means 'blocks' — Latin Americans commonly give directions in city blocks.
