If you want to access all the parts of the road in a program, then putting them in a list and using one of the list loop structures is the way to go. If you want to be able to move them all together, you can create a dummy object (or some other object that is easier to grab), and set the vehicle property of all the road pieces to the dummy object. Then when you move the dummy object, the whole road will go with it.

I’m attaching a screenshot that shows an example. In my example, the vehicle property of the road pieces is set to the road sign.
