For accomodating utilities
(iii) These environmental and economic effects together with any interference with or impairment of the use of the highway in such right-of-way which would result from the use of such right-of-way for the accommodation of such utility facility will be considered.(iv) [Reserved] (v) A utility strip will be established along the outer edge of the right-of-way by locating a utility access control line between the proposed utility installation and the through roadway and ramps.This includes utility installations within interchange areas which must be constructed or serviced by direct access from the main lanes or ramps.
Longitudinal use of such right-of-way by private lines is to be handled under the provisions of 23 CFR 1.23(c). (b) Since by tradition and practice highway and utility facilities frequently coexist within common right-of-way or along the same transportation corridors, it is essential in such situations that these public service facilities be compatibly designed and operated.The desired width is dependent upon the traffic volumes and speeds, and on the roadside geometry.The current edition ofthe AASHTO "Roadside Design Guide", should be used as a guide forestablishing clear zones for various types of highways and operating conditions. 319 shall be considered to be highway right-of-way. This subpart shall not be construed to alter the basic legal authority of utilities to install their facilities on public highways pursuant to law or franchise and reasonable regulation by highway agencies with respect to location and manner of installation. Therefore, it is necessary that such use and occupancy, where authorized, be regulated by highway agencies in a manner which preserves the operational safety and the functional and aesthetic quality of the highway facility.
