The installation of driveways and all access points along arterial highways must be in accordance with TxDOT’s .

For arterial highways constructed in developed or developing areas, it may be desirable to control access through right-of-way acquisition or by design (i.e., provision of frontage roads). Designed access control may be provided solely within interchange areas or continuously throughout a section of highway, depending on traffic volumes, the degree of roadside development, availability of right-of-way, and economic conditions.

On two-lane arterial highways, frontage roads or parallel service roads to serve small rural business communities or other developments should not be permitted.

To a driver unfamiliar with the local area, a frontage road takes on the appearance of a separate roadway of a multilane divided facility, thus resulting in the assumption that the two-way, two-lane highway is a one-way roadway. Where individual driveways are located within deep cut or high fill areas, driveways may be routed parallel to the highway for short distances to provide for a safe, economical junction with the highway.

All frontage road development must be in accordance with the rules contained in . See for additional information on frontage road access control.
