<p>A retractable road median (10) used to divide a road that may be retracted to allow vehicles to cross it, comprising a median assembly (20), a frame assembly (50), a winch assembly (70), and a longitudinal base assembly (120). The retractable road median (10) has means to move the median assembly (20) from a retraced position into an extracted position and vise versa. In the retracted position, a cavity below a surface, receives the median assembly (10) therein. The longitudinal base assembly (120) includes two angled lateral walls (122 and 124) that, in the extracted position, are in a substantially vertical disposition. In the retracted position, the median assembly (20) collapses into the cavity so that the angled lateral walls (152, 154, 156, and 158) rotate into a nearly horizontal position to cover the cavity entrance, permitting vehicles to cross to the other side.</p> |
