Section 19-105-11 - Overhead utility crossings

(a) The supporting structures including guy poles, guys, etc., of overhead utility lines crossing the freeway shall be located outside the outer edges of through-traffic roadway side slopes and preferably outside the control of access lines. In any case supporting poles shall be located at least 30 feet beyond the edge of shoulder. Where right-of-way lines and control of access lines are not one and the same, as where frontage roads are provided, supporting poles may be located in the area between them.

(b) Crossings of freeways by utility service connections shall not be permitted except where they qualify as an extreme case exception under section 2 of AASHO's "A Policy on the Accommodation of Utilities on Freeway Rights-of-way", adopted February 15, 1969.

(c) Overhead utility lines crossing the freeway shall have a vertical clearance above the highway of 18 feet or greater for telephone lines and 20 feet or greater for electric lines in accordance with State of Hawaii "Public Utilities Commission's Amended General Order No. 6" (Hawaii Administrative Rules, title 6, chapter 66).

(d) Where a utility follows a crossroad or street which is carried over or under a freeway, provisions should be made for the utility to cross the freeway on the location of the crossroad or street in such a manner that the utility can be serviced without access from the freeway through-traffic roadways or ramps. Generally, the utilities are to be located within the standard right-of-way of the crossroad or street, existing or relocated, and may cross over or under the freeway, provided installation and servicing thereof can be accomplished without access from the freeway through-traffic roadways or ramps.
