PURPOSE: This rule provides a uniform system for regulating the location, construction, maintenance, removal and relocation of utility facilities on the right-of-way of highways in the state highway system to provide for the public safety and to facilitate the construction and maintenance of these highways.

1. (1) Application.

   1. (A) The following rule is established for the location or relocation of utility facilities on the right-of-way of highways in the state highway system. Any location or relocation of utility facilities contrary to this policy is declared to be an interference with the construction, maintenance or operation of state highways and their right-of-way and is prohibited.
   2. (B) Except as described in this rule, all work to be performed on right-of-way of the state highway system in connection with the location, relocation or maintenance of utilities, and where the roadway, shoulders or right-of-way will be affected by the work, must be done only under a permit or agreement to be issued by authority of the Missouri Highways and Transportation Commission. Application for these permits may be made on forms provided for that purpose and shall state specifically the nature of the work to be performed. A deposit may be required to insure completion in accordance with the permit issued. Applications for permits may be obtained at any of the ten (10) district highway offices of the commission or by requesting the applications from the office of the Missouri Highways and Transportation Commission at Jefferson City, Missouri. Replacement of individual poles and attachments or other existing utility facilities where only spot excavation is required and which excavation is not between the shoulder lines of the highway may be considered as routine maintenance, and a permit will not be required, provided the company involved abides by all parking and access regulations contained elsewhere in this policy for the type of highway on which the maintenance work is to be performed. Where parking and access violations occur or if the right-of-way is left in an unsatisfactory condition, the offending utility owner may be required to secure a permit for future maintenance work on the rightof-way. The policies prescribed in this rule are intended to reflect general policies of the commission and specific application should be made and permit obtained for the contemplated work rather than to rely fully upon these rules.
   3. (C) In the event that utility lines or facilities are so damaged as to constitute an emergency situation directly affecting or endangering traffic on the highway or public health or safety, access is permitted to the damaged facility by leaving the through roadways at such points as may be necessary to effect emergency repairs, provided immediate notice is given to the State Highway Patrol and the commission’s district engineer.
   4. (D) This policy does not apply to utility lines for services to facilities required for operating the highway.

2. (2) Road Classification.

   1. (A) Interstate System or Other Freeways. Interstate highways and highways with fully controlled access.
   2. (B) High Type Roads. Roadways with a constructed base and/or a wearing surface (other than aggregate) of two inches (2") or more thickness which have limited access, but not fully controlled or no access control.
   3. (C) Low Type Roads. Roadways with an aggregate surface or an asphalt wearing surface which is less than two inches (2") in thickness.

3. (3) Definitions and General Information.

   1. (A) Ditch line. A break line where the roadway ditch meets the back slope. It is located at the lowest point of a V-bottom ditch or furthest point from the roadway of a flat bottom ditch where the roadway slopes back to the existing ground line.
   2. (B) Duct. An enclosed tubular casing, or raceway, for protecting wires, lines, or cables which is often flexible or semirigid (one to three percent (1–3%) diametric deflection). The casing, or raceway, is separate from the cable or conductor which passes through it.
   3. (C) Encasement. Encasement as used in this policy means the placing of an installation around and outside of an underground facility consisting of a larger conduit which will permit the removal and replacement of the facility. An alternate to the conduit type encasement would be reinforced concrete poured around the facility. Acceptable materials are described in subsection (5)(C).
   4. (D) Limits of interchanges. For the uniform handling of utility installations only, the limits of interchanges are the outside ramp curve points. 7 CSR 10-3
   5. (E) Minimum cover for new underground utilities shall be: forty-two inches (42") for all water lines (parallel and crossings); fortytwo inches (42") for fiber optic cable (crossings, encased in rigid conduit); seventy-two inches (72") for fiber optic cable (crossings encased in polyethylene (PE) pipe); thirty inches (30") for direct burial and in-trench fiber optic cable (parallel); twenty-four inches (24") for all other direct burial cable (parallel); seventy-two inches (72") for uncased polyethylene (PE) gas pipe crossings under ditches and roadways but thirty inches (30") elsewhere and thirty inches (30") for all other (such as, but not limited to, gravity sewers, force sewers and electric) underground utilities (parallel and crossings).
   6. (F) Normal right-of-way line. An imaginary line that connects sudden breaks in the major right-of-way points for roadways. Sight distance right-of-way points (triangles) at roadway intersections are not to be considered as sudden breaks for determining normal right-of-way.
