PURPOSE: A structure of a bridge shaped road sign and a construction method thereof are provided to remarkably reduce construction costs by easily connecting a horizontal pipe with a road sign to a connection pipe fixed to the top of a post. CONSTITUTION: A structure of a bridge shaped road sign comprises crisscross hollow parts(15), crisscross hangers, posts(30), horizontal pipes(50), a sign plate, and fasteners(40). The crisscross hollow parts are vertically formed in upper structures(11) of concrete foundation structures. The concrete foundation structures are composed of lower structures(11') and upper structures. The crisscross hangers are embedded in concrete through the bottom of the crisscross hollow parts. The posts are inserted into the crisscross hollow parts and have cutout grooves(31) and connection pipes(36). The cutout grooves are inserted into the crisscross hangers. The connection pipes are fixed to one side of upper through holes(38). The horizontal pipes are inserted into the connection pipes of the posts. The sign plate is installed in the horizontal pipes. The fasteners are composed of rock bolts(41) and nuts(42) and are inserted into the cutout grooves of the posts.
