§ 21-2 “Controlled-access facility” defined.

For the purposes of this subheading, a controlled-access facility is defined as a highway or street especially designed for through traffic, and over, from, or to which owners or occupants of abutting land or other persons have no right or easement or only a controlled right or easement of access, light, air, or view by reason of the fact that their property abuts upon such controlled-access facility or for any other reason. Such highways or streets may be freeways open to use by all customary forms of street and highway traffic; or they may be parkways from which trucks, buses and other commercial vehicles shall be excluded.
