Co-ordinated Locations for Lines. Utilization of the highways
is essential to the economical and efficient extension, operation and
maintenance of supply and signal facilities. To avoid unduly increasing the
number or difficulty of situations of crossings conflicts or inductive
exposures incident to the use of the same highway by two different kinds of
facilities, all lines, should in general, be located as follows:
(a) General Location.
(1) Where the conditions and character of the
circuits permit, joint use of poles by signal and supply circuits is generally
preferable to separate lines when justified by considerations of safety,
economy and convenience, and presuming satisfactory agreement between the
parties concerned as to terms and conditions.
(2) Where signal circuits and supply circuits
on the same highway are not to occupy joint poles or where either kind of
circuit is alone on a highway, all signal circuits should be placed on one side
of the highway and all supply circuits should be placed on the other side, so
that, as far as practicable, one side of any section of a highway will be
available as the signal side and one side as the supply side.
(3) Unnecessary crossings from side to side
of the highway should be avoided.
(b) Detailed Location.
(1) Local Signal Lines. Where to be located
on the same highway with local supply lines, joint use is generally preferable
to separate lines, except sometimes in rural districts and except where the
character of circuits involved makes separate lines on opposite sides of the
highway more desirable.
Where to be located on the same highway with transmission
lines, separate lines on opposite sides of the highway are generally preferable
unless a large number of service wire crossings would be involved, in which
case, joint use or other arrangements may be preferable.
(2) Toll or Through Signal Lines. Where to be
located on the same highway with local supply lines or lower voltage
transmission supply lines, separate lines on opposite sides of the highway are
generally preferable, unless a large number of service wire crossings would be
involved, in which case, joint use or other arrangements may be preferable.
Where proposed for location on the same highway or to follow
the same general direction with higher voltage transmission supply lines,
co-operative consideration should be given to the question of whether such
locations should be used, and if so, what specific co-ordinated methods are
necessary. Where to be located on the same highway with higher voltage
transmission supply lines, separate lines on opposite sides of the highway are
preferable.
(3) Local Supply
Lines. Where to be located on the same highway with local signal lines, joint
use is generally preferable to separate lines except sometimes in rural
districts and except where character of circuits involved makes separate lines
on opposite sides of the highway more desirable.
Where to be located on the same highway with toll or through
signal lines, separate lines on opposite sides of the highway are generally
preferable, unless a large number of service wire crossings would be involved,
in which case, joint use or other arrangements may be preferable.
(4) Transmission Supply Lines.
Where to be located on the same highway with local signal lines or shorter toll
or shorter trunk signal lines, separate lines on opposite sides of the highway
are generally preferable unless a large number of service wire crossings would
be involved, in which case, joint use or other arrangements may be preferable.
Where proposed for location on the same highway or to follow the same general
direction with longer toll or through signal lines, co-operative consideration
should be given to the question of whether such locations should be used and if
so, what specific co-ordinated methods are necessary. Where to be located on
the same highway with longer toll or through signal lines, separate lines on
opposite sides of the highway are preferable.
(5) Avoidance of Overbuilding. Overbuilding
of one line by another should be avoided, where practicable. Where necessary
for the two kinds of lines to occupy the same side of a highway joint use is
generally preferable to overbuilding.
(c) Other Rights of Way. The foregoing
principles, although specifically mentioning public highways, should govern
situations involving other similar rights of way, where
applicable.
