A freeway is defined as a highway or section thereof with full control of access which has been designated as such by order of the Commission. On Freeways, no vehicular access from the abutting property to the through traffic lanes is permitted except at interchanges constructed at intersecting streets and highways. Frontage roads may be constructed on controlled access highways and where constructed vehicular access from the abutting property to the frontage road will be permitted. The frontage road will then carry such traffic to a cross road or street with an interchange for entry into the through traffic lanes. Pedestrians crossing controlled access highways at grade is not permitted. Utility lines may be located on the right of way of controlled access highways when such location conforms with the requirements of the American Association of State Highway and Transportation Officials' Policy on the Accommodation of Utilities on Freeway Rights-of-Way and the regulations set out in the Standard Operating Procedures. Freeways may be developed by stage construction.
