Det ser ud til, at vejarbejdet fortsætter hele ugen, så vi må vælge en anden vej i morgen.

Det ser ud til is a very common Danish expression meaning it looks like or it seems that.

• det = it
• ser ud til = looks like / seems

In this sentence, det is a dummy subject, just like English it in It seems that... It does not refer to a specific thing.

So:

• Det ser ud til, at... = It looks like / It seems that...

You will hear this pattern a lot in Danish.

Here at means that and introduces a subordinate clause.

So the structure is:

• Det ser ud til, at vejarbejdet fortsætter hele ugen
• It looks like that the roadwork continues all week

In natural English, we often omit that, but in Danish it is very normal to include at in this kind of sentence.

Danish, like German, often makes compound nouns by joining words together.

• vej = road
• arbejde = work
• vejarbejde = roadwork

Then vejarbejdet adds the definite ending:

• vejarbejde = roadwork
• vejarbejdet = the roadwork

So vejarbejdet literally means the roadwork.

This is extremely common in Danish. Instead of separate words, Danish often combines them into one noun.

Because Danish often forms the definite article by adding an ending to the noun.

For neuter nouns:

• et arbejde = a job / a work
• arbejdet = the job / the work

Since vejarbejde is a neuter noun, the definite form is vejarbejdet.

So:

• et vejarbejde = a roadwork project
• vejarbejdet = the roadwork

This is different from English, where we put the before the noun instead of changing the ending.

Danish very often uses the present tense to talk about the future when the context makes the time clear.

• fortsætter = continues / is continuing / will continue

Because the sentence includes hele ugen and the situation is clearly about upcoming time, Danish does not need a special future form here.

So:

• vejarbejdet fortsætter hele ugen
  = the roadwork is continuing all week / will continue all week

This works much like English in sentences such as We leave tomorrow.

Hele ugen means the whole week or all week.

• hele = whole / entire
• ugen = the week

This is the normal way to say it in Danish.

So:

• hele dagen = the whole day
• hele natten = the whole night
• hele ugen = the whole week

Den hele uge is generally not the natural choice here. A learner should strongly prefer hele ugen in expressions like this.

Here så means so in the sense of therefore / as a result.

The sentence is built like this:

• It looks like the roadwork continues all week, so we have to choose another route tomorrow.

So så connects the first idea to its consequence.

Be careful: så can mean several things in Danish depending on context, including:

• so
• then
• such
• sometimes part of spoken emphasis

But here it clearly means so / therefore.

Here må means must / have to / need to.

• vi = we
• må = must / have to
• vælge = choose

So vi må vælge means we must choose or we’ll have to choose.

This use of må often expresses necessity caused by the situation, not necessarily an order from someone.

In this sentence, the roadwork creates the necessity:

• The roadwork continues all week, so we have to choose another route tomorrow.

This is a very common learner question.

In many contexts:

• må = must / have to, often because circumstances make it necessary
• skal = shall / will / am supposed to / have to, often with a sense of plan, obligation, or instruction

In this sentence, må fits well because the necessity comes from the roadwork.

• vi må vælge en anden vej
  = we have to choose another route

If you used skal, it might sound more like a plan, instruction, or requirement. Sometimes both are possible, but må is very natural here because the situation forces the choice.

Because vej is a common gender noun, not a neuter noun.

• en vej = a road / a way / a route

So the forms must match:

• en anden vej = another road / another route

If the noun were neuter, you would use et andet.

Examples:

• en bil → en anden bil
• et hus → et andet hus

Since vej takes en, the correct phrase is en anden vej.

Literally, vej often means road or way, but in this sentence en anden vej is best understood as another route.

So depending on context, vej can mean:

• a physical road
• a way
• a route
• even a method in some expressions

Here, because people are trying to get somewhere while roadwork is happening, another route is the most natural English interpretation.

I morgen means tomorrow and is a time expression.

In Danish, time expressions are often placed:

• at the beginning
• in the middle
• or at the end

The end position is very natural here:

• ... så vi må vælge en anden vej i morgen

It keeps the sentence smooth and makes i morgen apply clearly to vælge.

You could also say:

• ... så vi må i morgen vælge en anden vej

but that sounds more marked or formal. The version in your sentence is the most natural everyday order.

Because så here is functioning as a conjunction meaning so, connecting two clauses.

When så introduces a new main clause in this way, the normal word order is:

• subject + verb
• vi må

So:

• ..., så vi må vælge en anden vej

If something else were placed first in the clause, then Danish would use inversion:

• I morgen må vi vælge en anden vej

Here i morgen is first, so the verb comes before the subject.

But after conjunction så in this sentence, the normal order is simply:

• så vi må...

Yes, it is very normal in written Danish to place a comma before a subordinate clause introduced by at.

So:

• Det ser ud til, at vejarbejdet fortsætter hele ugen

This helps show where the main clause ends and the subordinate clause begins.

In modern Danish comma rules, usage can vary depending on the system being followed, but for learners, it is good to recognize that a comma before at is very common and standard-looking.

A useful way to think about it is:

• vej + arbejde + t

The tricky part is that compound words are pronounced as one unit. Also, spoken Danish often reduces sounds more than English learners expect.

A rough learner-friendly guide might be:

• vejarbejdet ≈ vye-ar-bye-dheth
  or more loosely vy-ar-bye-theth

But the exact pronunciation depends on accent and speed.

The main thing to remember is:

• the word is one compound
• the stress usually falls early in the compound
• the final -et is the definite ending

It is best to listen to native audio for this word, because Danish pronunciation is often less transparent than spelling.

Yes. Danish allows some flexibility, especially with time expressions.

For example:

• Det ser ud til, at vejarbejdet fortsætter hele ugen, så vi må vælge en anden vej i morgen.
• I morgen må vi vælge en anden vej, for det ser ud til, at vejarbejdet fortsætter hele ugen.

Both are natural, but they place the focus differently.

The original version first states the situation, then the consequence:

1. the roadwork continues
2. therefore we must choose another route tomorrow

That order is very logical and natural.
