Section 761.115.18. Longitudinal installations on nonfreeway primary highways.

       115.18(1) Location. Longitudinal utility facility installations should be located on uniform alignment as near as practical to the right-of-way line so as to provide a safe environment for traffic operations and to preserve space for future highway improvements and other utility installations.

       115.18(2) Underground installations.

        a.           No carrier of flammable, corrosive, expansive or unstable material shall be placed longitudinally within the right-of-way of a nonfreeway primary highway. Exceptions:

       (1)             A natural gas line with an operating pressure that is no greater than 150 pounds per square inch is permissible.

       (2)             The department may permit the placement of a natural gas line with an operating pressure that is greater than 150 pounds per square inch only if a suitable alternate location cannot be found.

        b.           On rural-type roadways, utility facilities shall be located in an area beyond the highway foreslope, right-of-way width permitting, except at locations where this is not acceptable, such as deep ravines or ditches.

        c.           On urban-type roadways, utility facilities should be located as near to the right-of-way line as practical and preferably not within the traveled way. A utility access placed within the right-of-way shall not protrude above the surrounding surface.

        d.           In general, utility facilities are not allowed in the median. However, in special cases the district representative may approve such an installation.
