The protective wall comprises a wall element (22), which is positioned upright in an application position and particularly in a orthogonal orientation along a traffic route to a horizontal plane angle. A pivotable construction (26) for pivoting the wall element from the application position to a resting position. The pivotable construction comprises two support arms (38) pivotable in a pivot axis (52). The wall element is rotatably mounted on the support arms relative to the rotating axes (44). The rotary and pivot axes run parallel to each other and relative to the horizontal plane.
