A traffic barrier composed of a unitary panel having a plurality of folds for permitting it to be folded into an A-frame composed of two message panels connected at an apex, the A-frame having a base. The folds in the unitary panel include: a center fold, which forms the apex of the A-frame two bottom folds each spaced a first predetermined distance from the center fold, which define a bottom panel adjacent each message panel, and two flange folds spaced a second predetermined distance from the center fold, which define a flange adjacent the end of each bottom panel. The base is established either by an interlocking tab and slot system located adjacent the flanges or by an adhesive interconnecting the two flanges.
