	Where the width of full depth pavement does not extend at least one (1) foot onto the shoulder, and the rumble strip must be placed on, or partially on, a shoulder with less than full depth pavement, as indicated on Std. Plan 626.00 (≤ 12’ Pavement Structure), the condition and depth of the shoulder structure should be evaluated prior to determining the location of the edgeline. If the shoulder condition and depth is deemed adequate to support routine off-tracking of traffic onto the rumble strip, the edgeline stripe should be placed over the rumble strip as shown in the standard plans (i.e., rumble stripe). If evidence suggests the shoulder condition or depth is inadequate to support routine off-tracking of traffic onto the rumble strip, placement of the edgeline stripe and rumble strip may be considered as follows:		Where the width of full depth pavement does not extend at least one (1) foot onto the shoulder, and the rumble strip must be placed on, or partially on, a shoulder with less than full depth pavement, as indicated on Std.

If evidence suggests the shoulder condition or depth is inadequate to support routine off-tracking of traffic onto the rumble strip, placement of the edgeline stripe and rumble strip may be considered as follows:

	:* For major roads, the edgeline stripe should be placed in the travel lane with the rumble strip placed 4 inches beyond the edgeline stripe. The rumble strip should not be moved further out from the centerline. A design exception shall be submitted when separating the edgeline stripe from the rumble strip. See [[231.4 Shoulder Width\|EPG 231.4 Shoulder Width]] for recommended shoulder widths.		* For major roads, the edgeline stripe should be placed in the travel lane with the rumble strip placed 4 inches beyond the edgeline stripe. The rumble strip should not be moved further out from the centerline. A design exception shall be submitted when separating the edgeline stripe from the rumble strip. See [[231.4 Shoulder Width\|EPG 231.4 Shoulder Width]] for recommended shoulder widths.
			* For minor roads, a mini rumble strip (6 inches wide) should be placed along the edge of the travel lane structure provided sufficient driving width remains. If sufficient driving width cannot be achieved, rumble strips should not be used. When a centerline rumble is not used, sufficient driving width is defined as having a minimum of 10 ft. between the centerline joint and the inside edge of the edgeline rumble. When a centerline rumble is used, sufficient driving width is defined as having a minimum of 10 ft. between the edge of the centerline rumble and the inside edge of the edgeline rumble. The edgeline stripe (4 inches) should be placed over the inside edge of the mini rumble strip (i.e., mini rumble stripe).
			* '''District Responsibility.''' Collaboration with the Central Office Highway Safety and Traffic Division and the Design Division is necessary prior to approval of a design exception to omit or modify these system-wide safety improvements (such as rumble strips) on a project. Design exceptions should include documentation of the crash history and safety analysis of the route, or segment of the route, where the design exception is being applied.

	~~:* For minor roads~~, ~~a mini rumble strip (6 inches wide) should be placed along~~ the ~~edge of the travel lane structure provided sufficient driving width remains.

In urban areas, where the rumble noise has been identified as a significant issue, the preferred method of mitigation is to place the edgeline stripe on the edge of the travel lane and the rumble strip 1 ft. onto the shoulder pavement.

			In order to maintain the integrity of the rumble strip and the pavement, the pavement material must be either concrete or the top lift of bituminous material must be at least 1 inch thick. Edgeline rumble strips are to be milled into bituminous and portland cement concrete. Edgeline rumble strips are omitted through side road approaches, entrances, and median crossovers as shown in Standard Plan 626.00.
