Abstract

Abstract For displaying official traffic and roadway messages to oncoming motorists, a driver information sign is provided for disposition in proximate generally perpendicular relation to a vehicular traffic lane and comprises a series of parallel letter supports formed by aluminum extrusions cut to length and spaced apart by stacks of intervening spacers bound together by tie rods to form a sturdy and lightweight assembly. The letter supports have grooved frontal edges defining a message face wherein one or more rows of message letters having individual structural integrity span adjacent letter supports and are attached thereto by screws. The spacers and letter supports form wind tunnels that minimize wind forces on the sign by passing wind freely through the message face and the sign structure. Laterally deflected excursions of the letter supports block vision through the sign and define a visually continuous background surface for lettering in the message face. Anchor bolt receiving grooves formed in the rear edges of a dispersed plurality of the letter supports receive sign supporting forces that can be widely dispersed to avoid stress concentrations and patterned to accommodate a wide variety of supporting structures. If desired, the letter supports can be shaped along both edges for attachment of letter characters in two message faces on opposite sides of the sign.
