Distance from intersection | Number of signs |
0 - 2 miles. . . . | 0 |
2 - 5 miles. . . . | 6 |
More than 5 miles. . . . | Average of one sign per mile |
The specified distances shall be measured to the nearest point of intersection of the traveled way of the exit roadway and the main-traveled way of the interstate highway.
(ii) Not more than two such signs may be permitted within any mile distance and no such signs may be permitted less than one thousand feet apart.
(iii) Type 1, 2, and 3 signs shall not be considered in determining compliance with the above spacing requirements.
(iv) Type 4 and Type 5 signs may not be permitted adjacent to interstate highway right of way within the limits of an interchange, including its entrance or exit roadways.
(v) Type 4 and Type 5 signs visible to interstate highway traffic, which has passed an entrance roadway, may not be permitted within one thousand feet of the point where the entrance roadway intersects with the interstate highway. The distance shall be measured from the intersection point farthest from the preceding interchange.
(vi) Not more than one Type 4 or Type 5 sign, advertising activities conducted as a single enterprise or giving information about a single place, may be erected or maintained in such manner as to be visible to traffic moving in any one direction on any one interstate highway.
(e) The spacing of Type 4 and Type 5 signs visible to primary highways shall be restricted as follows:
(i) On limited access highways, no two signs may be spaced less than one thousand feet apart, and no sign may be located within three thousand feet of the center of a grade separated interchange, a safety rest area, or an information center, or within one thousand feet of an at-grade intersection. Not more than a total of five sign structures may be permitted per mile, including both sides of the highway. Double-faced (flanking or side-by-side) signs are prohibited.
(ii) On nonlimited access highways inside the boundaries of incorporated cities or towns, not more than a total of four sign structures, including both sides of the highway, may be permitted within a space of six hundred sixty feet or between platted intersecting streets or highways. There shall also be a minimum of one hundred feet between sign structures, including both sides of the highway.
(iii) On nonlimited access highways outside the boundaries of incorporated cities or towns, the minimum spacing between sign structures on each side of the highway shall be five hundred feet.
(iv) Back-to-back signs and V-type signs shall be considered one sign structure.
(f) The minimum space between sign structures located on the same side of the highway shall be measured between two points along the nearest edge of pavement. The measurement points are established at the origin of lines extending perpendicular from the edge of pavement to the apparent centers of the sign structures.
(g) The minimum space between sign structures located on opposite sides of the highway shall be measured in the applicable manner following:
(i) Along tangent sections, sign spacing is measured between two points along the edge of pavement in the increasing milepost direction of travel. One measurement point is established at the origin of a line extending perpendicular from the edge of pavement to the apparent center of the sign structure located in the increasing direction of travel. The second measurement point is established at the origin of a line extending perpendicular from the edge of pavement to the apparent center of the sign structure located in the decreasing direction of travel.
(ii) Along horizontal curve sections, sign spacing is measured between two points on the edge of pavement along the arc on the inside of the curve. One measurement point is established at the origin of a line extending perpendicular from the edge of pavement to the apparent center of the sign structure located along the highway in the increasing milepost direction of travel. The second measurement point is established at the origin of a line extending perpendicular from the edge of pavement to the apparent center of the sign structure located along the highway in the decreasing milepost direction of travel.
(h) Type 1, 2, 3, 7, and 8 signs shall not be considered in determining compliance with the above spacing requirements.
(i) Type 4 and Type 5 signs may be permitted within commercial and industrial areas adjacent to interstate and primary highways, provided that spacing is available as specified in (d) and (e) of this subsection.
(j) Type 4 and Type 5 signs are not permitted visible to the scenic system.
(k) Pursuant to the 1991 Intermodal Surface Transportation Efficiency Act, a National Scenic Byway Demonstration Project is established on State Route 101, from the Astoria/Megler Bridge to Fowler Street in Raymond and from the junction with State Route 109 near Queets to the junction with State Route 5 near Olympia. No new Type 4 or Type 5 signs may be permitted within the limits of this project. Type 4 or Type 5 signs installed prior to July 25, 1993, may remain as nonconforming signs.
(6) Type 6 - Landmark signs.
(a) Type 6 signs shall have been lawfully in existence on October 22, 1965, and have historic or artistic significance, including signs on farm structures or natural surfaces.
(b) Historic or artistic significance shall be determined by the department and approved by the Federal Highway Administration.
(c) Within the limits of the National Scenic Byway Demonstration Project identified in (5)(h) of this subsection, Type 6 signs may remain as nonconforming signs.
(7) Type 7 - Public service signs located on school bus stop shelters. Type 7 signs may display safety slogans or messages, and identify the donor, sponsor, or contributor of a school bus stop shelter. No other message(s) may be displayed.
(a) Safety slogans or messages must occupy at least sixty percent of the sign area, and appear more predominant than the name of the donor, sponsor, or contributor.
(b) Type 7 signs may be located on school bus stop shelters only as authorized or approved by state law or regulation, or city or county ordinance or resolution, and may be installed visible to primary and scenic system highways.
(c) Type 7 signs may not exceed thirty-two square feet. A sign shall not protrude above the roofline or beyond the sides of the school bus stop shelter.
(d) Not more than one sign on each shelter may face in any one direction.
(e) The act does not regulate Type 7 signs with regard to zoning requirements or spacing between Type 7 signs and other types of signs.
(8) Type 8 - Temporary agricultural directional signs. Type 8 signs provide directional information to places of business having seasonal agricultural products for sale.
(a) Type 8 signs may display the business name, product(s) for sale, travel direction, and travel distance to the nearest mile from the state highway to the business.
(b) Type 8 signs may not exceed thirty-two square feet.
(c) There shall be at least three hundred feet spacing between Type 8 signs.
(d) Not more than two signs advertising a place of temporary agricultural business may be installed visible to traffic proceeding in one direction of travel on any one state route.
(e) Premises on which the seasonal agricultural products are sold must be within fifteen air miles of the state highway.
(f) Type 8 signs may be posted only during the period of time the seasonal agricultural product(s) is being sold.
(g) Any necessary supplemental follow-through signs along city streets or county roads must be installed before the Type 8 signs may be installed visible to the state highway.
(h) The signs may be installed visible to primary system highways outside incorporated cities or towns, and scenic system highways.
(i) Type 8 signs may not be installed visible to interstate highways, including interstate highways that are also part of the scenic system, or visible to primary system highways within incorporated cities or towns.
(j) The act does not regulate Type 8 signs with regard to zoning requirements or spacing between Type 8 signs and other types of signs.
