في حينا شارع كبير، وقرب هذا الشارع مركز جديد.

It literally means in our neighborhood.

• في = in
• حيّ = neighborhood, district, quarter
• -نا = our

So في حيِّنا means in our neighborhood. In normal Arabic writing, short vowels are usually not written, so you see حينا instead of the fully vocalized حيِّنا.

Arabic often leaves out a present-tense verb like there is/there are in this kind of sentence.

So في حينا شارع كبير is literally something like In our neighborhood, a big street, but the natural meaning is There is a big street in our neighborhood.

This is a very common Arabic pattern. You could also say يوجد شارع كبير في حيِّنا, but the version in your sentence is simpler and very natural.

Because Arabic often starts existential sentences with the place or location.

So:

• في حينا شارع كبير = In our neighborhood, there is a big street
• شارع كبير في حينا is possible, but it sounds less like a neutral there is sentence and more like you are highlighting a big street

Starting with the location is a very common way to introduce something that exists somewhere.

Because the sentence is introducing the street for the first time, so it is indefinite: a big street, not the big street.

• شارع كبير = a big street
• الشارع الكبير = the big street

After that, the street becomes identifiable in the discourse, so the second clause can refer back to it as هذا الشارع = this street.

In Arabic, adjectives normally come after the noun they describe.

So:

• شارع كبير = a big street
• مركز جديد = a new center

This is the normal order in Arabic: noun + adjective.

Because the nouns they describe are indefinite.

In Arabic, adjectives match the noun in definiteness:

• شارع كبير = a big street
• الشارع الكبير = the big street
• مركز جديد = a new center
• المركز الجديد = the new center

So if the noun is indefinite, the adjective is also indefinite.

In Modern Standard Arabic, when a demonstrative like هذا directly modifies a noun, the noun is usually definite with الـ:

• هذا الشارع = this street

But:

• هذا شارع usually means This is a street

So the difference is important:

• هذا الشارع = this street
• هذا شارع = this is a street

Because شارع is a masculine noun.

In Arabic, demonstratives must match the gender of the noun:

• هذا الشارع = this street because شارع is masculine
• هذه السيارة = this car because سيارة is feminine

So هذا is correct here.

قرب means near or close to here.

So:

• قرب هذا الشارع = near this street

The second clause works like the first one:

• وقرب هذا الشارع مركز جديد
• And near this street, there is a new center

So again, Arabic is using a location phrase + indefinite noun structure.

Because قرب can directly connect to a following noun phrase in MSA.

So both of these are possible:

• قرب هذا الشارع = near this street
• بالقرب من هذا الشارع = near this street

The version in your sentence is shorter and perfectly normal. Learners often first meet بالقرب من, but قرب by itself is also common and important.

A fully vocalized version would be:

فِي حَيِّنا شارِعٌ كَبيرٌ، وَقُرْبَ هٰذا الشّارِعِ مَرْكَزٌ جَديدٌ.

A few useful things to notice:

• حيِّنا is after في, so it is in the genitive
• شارعٌ and مركزٌ are the main nouns being introduced, so they are nominative
• كبيرٌ and جديدٌ match those nouns
• قربَ is commonly treated here as an adverbial noun, and الشارعِ after it is in a genitive relationship

In everyday writing, these endings are normally not written, which is why the original sentence looks much simpler.
