Current through Register Vol. 52, No. 6, March 21, 2025
A. All work and materials shall conform to
Administration specifications, standards, and addenda current at the time of
the permit grant.
B. All work is
subject to Administration periodic inspection and final approval.
C. Entrance Location.
(1) The number and location of entrances
which may be granted shall be based on usage, interior and exterior traffic
patterns, and current design policy of the Administration.
(2) A maximum of two entrances may be allowed
in the first 200 feet of frontage. For each additional 100 feet of frontage, a
maximum of one entrance may be permitted, subject to the final determination of
the Administration in order to promote highway safety. Regardless of frontage,
a development may be restricted to a single entrance and exit
location.
(3) Entrances shall
adhere to the safety criteria for acceptable intersection or stopping sight
distance conditions, or both, in accordance with current Administration
standards and engineering practices.
D. Entrance Width.
(1) The maximum width for a two-way access at
90 degrees shall be 35 feet, except where traffic, type of access, or type or
size of using vehicles justify a variation of the 35-foot maximum. The minimum
width of a two-way access is 25 feet.
(2) One-way access at 45 degrees to 90
degrees shall have a maximum width of 20 feet. The minimum width should also be
20 feet. Exceptions based on existing conditions and current adopted design
criteria may be made by the State Highway Administration.
(3) Entrance width shall be measured
perpendicular to the center line of the entrance.
E. Channelization.
(1) Unless other channelization is acceptable
to the Chief, Engineering Access Permits Division, all entrances permitted
under these regulations shall be channelized, for their entire frontage, as
follows:
(a) Projects funded in the
Consolidated Transportation Program for construction within 6 years, whether or
not advertised-temporary bituminous curb may be used;
(b) Highways with safety grading-type C
concrete curb, or concrete curb and gutter;
(c) All other situations-type A concrete
curb, or curb and gutter;
(d) On
existing curbed State highways, developers shall generally be required to
replace existing curbs in kind; and
(e) All improvements shall provide for
increased safety and access for pedestrian and bicycle traffic in a manner
acceptable to the Administration.
(2) The front curb shall be constructed on a
line 14 feet to 17 feet from and parallel to the existing edge of the road as
determined by the Administration. The rear edge of the back curb shall be
constructed on the existing right-of-way line where existing right-of-way is
sufficient for ultimate roadway design. Where the existing right-of-way is not
sufficient to contain the ultimate improvements, the curb should be placed on
the alignment of the proposed right-of-way line. The area between the curbs
shall be properly graded and paved, sodded or seeded. Signs, structures, etc.
may not be placed in this area or elsewhere within the highway
right-of-way.
(3) In rural areas
where a drainage ditch of sufficient depth to act as a barrier will remain
paralleling the highway, or the height and grade of slope of the property
abutting the State highway is greater than 3 feet and 2:1, respectively, the
back curb (on the right-of-way line) may be eliminated at the discretion of the
State Highway Administration. However, the front curb shall be constructed. If
the topography of the area is changed by the owner so that the side ditches or
cut slopes are eliminated, a curb or a curb and gutter along the right-of-way
will be required.
(4) Ultimate
Section.
(a) Rural Section-four lane divided
highway, 50 foot-76 foot median Minimum 150 foot right-of-way*
(b) Urban Section-four lane divided
highway-20 foot-34 foot median Minimum 120 foot right-of-way*
(c) Street Section-undivided 36 foot-60 foot
street Minimum 80 foot right-of-way*
*Right of way widths based on minimum slope requirement.
Increased slope requirement will necessitate wider right-of-way width.
F. Curb
Length.
(1) The minimum curb length between
entrances is 40 feet, consisting of a 10-foot radius-20-foot tangent-10-foot
radius.
(2) The minimum tangent
curb length between the radius point of the entrance and the property line is
10 feet.
G. Intersection
Radius.
(1) At the intersection of a State
highway with a minor road (county, municipal, etc.), the minimum radius shall
be a 30-foot or equivalent three-centered compound curve and provide for
increased safety and access for pedestrian and other intended traffic in a
manner acceptable to SHA.
(2) At
the intersection of a State highway with a State highway or other major
arterial highway, the minimum radius shall be a 50-foot or equivalent
three-centered compound curve and provide for increased safety and access for
pedestrian and other intended traffic in a manner acceptable to SHA.
(3) At intersections with channelization
providing for free right turns, the above-mentioned dimensions will be
increased as directed by the State Highway Administration in accordance with
accepted engineering practices.
(4)
There shall be a minimum 20-foot tangent distance between the intersection
radius and the first permitted entrance.
H. Paving. Paving within the State Highway
Administration right-of-way, including storage lanes, bypass lanes, speed
change lanes, crossovers, entrances proper, etc., shall be in accordance with
current State Highway Administration paving specifications or as stipulated in
the permit, or both.
I. Median
Openings. The granting of a permit for access onto a dual type facility may not
be construed to mean that an opening in the median will be permitted.
J. Pump Island Location. In order that the
entrances operate at maximum efficiency, it is recommended that the roadside
face of the pump island of filling stations be set a minimum of 12 feet,
preferably 15 feet, from the property line. Pump setback lines are subject to
the regulations of the pertinent local subdivision.
K. Building Setback. In order that the
entrances operate at maximum efficiency, it is recommended that the minimum
desirable building setback line be 30 feet. Building setback lines are subject
to the regulations of the pertinent local subdivision and appropriate design
criteria.
L. Angular Entrances.
Angular entrances may not extend beyond the property line when paving a
driveway to highway, or beyond access control limits. The point of control
shall be the extension of the property line from its intersection at the
existing State Highway Administration right-of-way line normal or radial to the
edge of the pavement. One-way angular entrances shall be at 45
degrees.
M. Ditch Cross Sections.
Ditch cross sections shall be in accordance with current adopted State Highway
Administration criteria.
