Rule 761-115.17 - Nonfreeway primary highways

(1) Clear zone requirements and aboveground obstructions. Subrule 115.5(5) applies. In addition:

a. In urban areas with rural-type roadways and speed limits of 45 miles per hour or lower, a permanent, aboveground obstruction shall be located at least 15 feet from the edge of the paved traveled way or beyond the highway foreslope, whichever location is farther from the traveled way.

b. On urban-type roadways, the face of a permanent, aboveground obstruction shall be located no closer than ten feet from the back of the curb. In areas with parking or auxiliary lanes, aboveground obstructions shall be located no closer than two feet behind the back of the curb or a minimum of ten feet from the edge of the traveled way, whichever location is farther from the traveled way.

c. In rural areas with rural-type roadways, poles, guys and other supporting structures and related aboveground facilities should be located as near to the right-of-way line as practical.

(1) These aboveground obstructions shall be located in an area beyond the clear zone or the highway foreslope, whichever area locates the obstruction a greater distance from the edge of the traveled way, right-of-way width permitting.

(2) In individual cases, the department may require the use of self-supporting poles or towers, double arming and insulators, breakaway devices and dead-end construction.

d. In suburban areas with rural-type roadways and speed limits of 45 miles per hour or lower, utility poles shall be located at least 15 feet from the edge of the paved traveled way or beyond the highway foreslope, whichever location is farther from the traveled way. The preferred location is near the right-of-way line.

e. Poles, guys, anchors and other appurtenances shall not be located in ditches, at drainage structure openings or on roadway shoulders. All poles, guys, anchors and other appurtenances shall be located to minimize interference with the maintenance operations of the department.

f. The district representative may approve the adjustment of minimum setback distances for poles and other appurtenances that have a breakaway design.

(2) Reserved.
