The state of Texas is locally governed by Counties and not Parishes as in some countries. In Texas, if you see a road designated on the map as Pr 1111, that means Private Road, not Parish road.

The equivalent of a Parish Rd (a road maintained by a local government entity) would be CR 1111 which stands for County Road.

CR roads are often gravel or similar surfaces, especially in rural areas which are not near a major metropolitan area.
