Control of Access Definitions
Listed in Order of Mobility Function
Full Control of Access
Connections to a facility provided only via ramps at interchanges. All cross-streets
are grade-separated. No private driveway connections allowed. A control of access fence
is placed along the entire length of the facility and at a minimum of 1000 feet beyond
the ramp intersections on the Y lines (minor facility) at interchanges (if possible).
Limited Control of Access
Connections to a facility provided only via ramps at interchanges (major crossings)
and at-grade intersections (minor crossings and service roads). No private driveway
connections allowed. A control of access fence is placed along the entire length of
the facility, except at intersections, and at a minimum of 1000 feet beyond the ramp
intersections on the Y lines (minor facility) at interchanges (if possible).
Partial Control of Access
Connections to a facility provided via ramps at interchanges, at-grade intersections,
and private driveways. Private driveway connections are normally defined as a maximum
of one connection per parcel. One connection is defined as one ingress and one egress
point. The use of shared or consolidated connections is highly encouraged.
Connections may be restricted or prohibited if alternate access is available through
other adjacent public facilities. A control of access fence is placed along the entire
length of the facility, except at intersections and driveways, and at a minimum of 1000
feet beyond the ramp terminals on the minor facility at interchanges (if possible).
No Control of Access
Connections to a facility provided via ramps at interchanges, at-grade intersections,
and private driveways. No physical restrictions, i.e., a control of access fence,
exist. Normally, private driveway connections are defined as one connection per parcel.
Additional connections may be considered if they are justified and if such connections
do not negatively impact traffic operations and public safety.
