To provide a sign for a road enabling the column portions and the beam portion to be easily attached and detached for part replacement.

A beam is installed between poles. The poles comprise respective joints into which the ends of the beam can be inserted. Column side engagement parts are formed in the joints, respectively, and beam side engagement parts engageable with and disengageable from the column side engagement parts are formed at both ends of the beam, respectively, so that the column side engagement parts and the beam side engagement parts are engaged with each other when the beam is rotated in one direction. Since the engagement parts can be engaged with or disengaged from each other by rotating the beam in the direction or in the reverse direction, the beam and the poles between which the beam is installed can be easily attached and detached. Consequently, the beam can be replaced.
