Are they forced by law to return the roads to their original state

Onlar yasa ile mi ilk yurtları olan sokaklara geri dönmeye zorlandılar?

(some uses of´original´in Turkish
 original state= ilk yurt(about origin)
 original sculpture = özgün heykel(unusual)
 original Rolex= sahici(or orjinal) Rolex (not fake))
 

I don´t think "state" here is related with it´s meaning fx. in "United States", hence that translation is a little off.

"Yolları eski haline döndürmeleri yasal bir zorunluluk mu?" = "Is it a legal obligation that they need to restore the roads to their original state". (If this is what you were trying to say)

yes thats what I meant ,thanks to you both for your time
