    Abstract: Ramp-guard for placement on roadways preventing wrong-way travel. Includes a base having a center cutout, and screw holes utilized to attach base to concrete frame. Extending upward from the base is tensioning spring having horizontal section lying flat upon base at traffic entering end. Spring is bent upward at angle which angular section passes through base cutout. The end of angular section of spring contacts ramp and applies upward force forcing ramp up when not under vehicular weight. A warning sign is oriented vertically on the side of ramp guard device when spring is not compressed and rotates pivotally when spring becomes compressed. Ramp guard is positioned so that end with horizontal aspect of spring faces traffic entering direction. If vehicle travels onto ramp in correct direction, spring is compressed and ramp is flattened, permitting traffic flow. If vehicle enters from wrong direction, driver sees ramp and warning sign and turns around.
