Current through Register Vol. 54, No. 44, November 2, 2024
(a)
General rule. Driveways shall be located, designed,
constructed and maintained in such a manner as not to interfere or be
inconsistent with the design, maintenance and drainage of the
highway.
(b)
General
location restrictions. Access driveways shall be permitted at
locations in which:
(1) Sight distance is
adequate to safely allow each permitted movement to be made into or out of the
access driveway.
(2) The free
movement of normal highway traffic is not impaired.
(3) The driveway will not create a
hazard.
(4) The driveway will not
create an area of undue traffic congestion on the highway.
(c)
Specific location
restrictions. Specific location restrictions shall include the
following:
(1) Access driveways may not be
located at interchanges, ramp areas, or locations that would interfere with the
placement and proper functioning of highway signs, signals, detectors, lighting
or other devices that affect traffic control.
(2) The location of a driveway near a
signalized intersection may include a requirement that the permittee provide,
in cooperation with the municipality, new or relocated detectors, signal heads,
controller and the like, for the control of traffic movements from the
driveway.
(3) Access to a property
which abuts two or more intersecting streets or highways may be restricted to
only that roadway which can more safely accommodate its traffic.
(4) The Department may require the permittee
to locate an access driveway directly across from a highway, local road, or
access driveway on the opposite side of the roadway if it is judged that offset
driveways will not permit left turns to be made safely or that access across
the roadway from one access to the other will create a safety hazard.
(d)
Local roads.
An access intended to serve more than three properties or to act as a
connecting link between two or more roadways shall be, for the purpose of this
chapter, considered a local road and not a driveway regardless of its
ownership. As such, its design must be in accordance with the Department's
current standards governing the design of local roads. All other requirements
of this chapter shall be complied with before the local road will be allowed
access onto a State highway.
(e)
Number of driveways. The number and location of entrances
which may be granted will be based on usage, interior and exterior traffic
patterns, and current design policy of the Department.
(1) Normally, only one driveway will be
permitted for a residential property and not more than two driveways will be
permitted for a nonresidential property.
(2) If the property frontage exceeds 600
feet, the permit may authorize an additional driveway.
(3) Regardless of frontage, a development may
be restricted to a single entrance/exit driveway, served by an internal
collector road separated from the traveled way.
(f)
Approaches to driveways.
Driveway approaches shall conform to the following standards:
(1) The location and angle of an access
driveway approach in relation to the highway intersection shall be such that a
vehicle entering or leaving the driveway may do so in an orderly and safe
manner and with a minimum of interference to highway traffic.
(2) Where the access driveway approach and
highway pavement meet, flaring of the approach may be necessary to allow safe,
easy turning of vehicular traffic.
(3) Where the highway is curbed, driveway
approaches shall be installed 1 1/2 inches above the adjacent highway or gutter
grade to maintain proper drainage. See Figure 5.
