Divided Highways and Freeways.

Rest and picnic areas on divided highways and freeways that have been modified to meet ADA requirements should be signed with the D9-6 accessibility plaque as illustrated in Figure 7-17. The D9-6 accessibility plaque should be attached to the parent sign, not to the parent sign supports (see Figure 7-17). The preferred position is above the parent sign, but if it is mounted below, a 7-foot minimum clearance between the bottom of the plaque and the edge of the pavement surface must be maintained.

Conventional Roadways.

Rest and picnic areas on conventional roadways that have been modified to meet ADA requirements should be signed with the accessibility plaque, indicating that the facility provides ADA accessibility to one or more picnic areas. The D9-6a accessibility plaque may be attached above or below existing advance and directional REST AREA and PICNIC AREA ( ) signs or incorporated as a standard design for new signs (Figure 7‑18). If the plaque is mounted below the parent sign, a 7-foot minimum clearance between the bottom of the plaque and the edge of the pavement surface must be maintained.
