Description: The SafeSign Support System test installation consisted of a 72-inch x 144-inch extruded aluminum sign mounted 84 inches above grade on two sign post assemblies spaced 88 inches center to center. The post assemblies were constructed of 4-inch, 8-gauge ASTM 500 Gr C square steel tubing with a hinge connection joining the upper square tubing (attached to the sign) with the lower square tubing that extended upward from the slip base that was located near grade. The interface of the slip base was located approximately 3 inches above grade. From the slip base, a 96-inch long section of 4½-inch, 7 gauge ASTM 500 Gr B square tubing was embedded into the soil.
