La carretera hasta el pueblo tiene ochenta kilómetros, así que saldremos temprano.

Spanish often uses tener to talk about measurements such as length, duration, or age.

So la carretera ... tiene ochenta kilómetros literally means the road ... has eighty kilometres, but naturally it means the road is eighty kilometres long or it’s eighty kilometres to the town.

This is a normal Spanish structure. Similar examples:

• La película tiene dos horas. = The film is two hours long.
• El puente tiene cien metros. = The bridge is one hundred metres long.

Here hasta means up to / as far as / all the way to.

So la carretera hasta el pueblo refers to the stretch of road that goes up to the town. In this sentence, it helps define the distance involved.

A learner might expect al pueblo, but hasta el pueblo emphasizes the full distance from here to the town.

Sometimes yes, but the meaning is slightly different.

• hasta el pueblo focuses on the distance as far as the town
• al pueblo usually means to the town, often more like destination than measured extent

In this sentence, hasta el pueblo fits well because the speaker is talking about how long the route is.

Spanish often uses the definite article more than English does.

Here el pueblo means the town: a specific town that both speaker and listener already know about.

Spanish usually needs the article in this kind of phrase:

• Voy al pueblo. = I’m going to the town / village.
• La carretera hasta el pueblo... = The road to the town...

Leaving out el would sound incomplete here.

Pueblo can mean village, small town, or sometimes just town, depending on context.

In Spain, pueblo often suggests a smaller place than a ciudad. So it usually gives the idea of a village or small town rather than a big city.

Así que means so, therefore, or so then. It introduces a consequence.

In the sentence:

• La carretera hasta el pueblo tiene ochenta kilómetros = the distance is long
• así que saldremos temprano = so we’ll leave early

It connects cause and result.

Compare:

• porque = because
• así que = so / therefore

So:

• Saldremos temprano porque la carretera... = We’ll leave early because...
• La carretera..., así que saldremos temprano. = The road is long, so we’ll leave early.

Both are possible.

• saldremos = we will leave
• vamos a salir = we’re going to leave

In modern Spanish, both can talk about the future. The simple future (saldremos) is very common and natural here, especially in neutral or slightly more formal narration.

So:

• Así que saldremos temprano = perfectly natural
• Así que vamos a salir temprano = also natural, a bit more conversational in some contexts

Saldremos comes from salir = to leave / to go out.

It is irregular in the simple future. Instead of using the full infinitive salir-, it uses the stem saldr-:

• saldré = I will leave
• saldrás = you will leave
• saldrá = he/she will leave
• saldremos = we will leave
• saldréis = you all will leave
• saldrán = they will leave

This same kind of irregular future happens with other verbs too:

• tener → tendré
• poner → pondré
• venir → vendré

Because Spanish usually drops subject pronouns when the verb ending already shows who the subject is.

Saldremos clearly means we will leave, so nosotros is unnecessary.

You could say nosotros saldremos temprano, but that would add emphasis, for example:

• Nosotros saldremos temprano, pero ellos no. = We will leave early, but they won’t.

Here temprano is an adverb, meaning early.

It describes when we will leave:

• Saldremos temprano. = We’ll leave early.

As an adjective, it can also mean early:

• una hora temprana = an early hour

But in your sentence, it functions adverbially.

Kilómetros has a written accent because the stress falls on ló: ki-LÓ-me-tros.

Without the accent, Spanish stress rules would make it sound different. The accent mark shows the correct pronunciation.

The same is true for así, which also needs an accent:

• así = like this / so

Yes. Spanish has several natural ways to express the same idea. For example:

• Hay ochenta kilómetros hasta el pueblo, así que saldremos temprano.
• Hasta el pueblo hay ochenta kilómetros, así que saldremos temprano.
• El pueblo está a ochenta kilómetros, así que saldremos temprano.

These all express roughly the same idea, but the original sentence focuses specifically on the road / route.

Not exactly. Carretera usually means a road, especially one for cars, often a main road or highway-type road between places.

Depending on context:

• carretera = road
• camino = path, track, way
• calle = street

So la carretera hasta el pueblo suggests the road route leading to the town, not just any path.
