Any proposal from an Irrigation District for overhead piping across the highway R/W shall be submitted to the State Bridge Engineer for a design review.
The minimum vertical clearance above the high point of the roadway template shall be 20 feet.
The preferred method of crossing the highway R/W is the installation of a siphon with watertight joints.

(a) Crossing of the Right-of-Way.
(i) The provisions of Section 3 (a) i, ii, iv, vii, viii and ix shall apply.
(ii) Open ditches may be allowed if they do not fall within the clear roadway recovery area and extenuating circumstances prevent the installation of the ditches outside of the highway R/W.
If open ditches are allowed on the highway R/W, they shall be concrete lined and located as close to the highway R/W line as possible.
(iii) Ditch rider or maintenance road approaches to the highway shall be constructed to Department specifications and in a location that meets all safety requirements, and may require the placement of gates and/or cattle guards at the R/W line.
Section 5. All Roads. If an agricultural operation adjacent to the highway R/W changes from surface irrigation to pumped, pipeline, or sprinkler irrigation, any existing irrigation culverts may be used as a casing for the irrigation pipeline.
Location of the pipeline, depth of cover, filling of open ditches, and restoration of the highway R/W shall be as directed by the Department’s engineer.
