A wind break having a blade is mounted between an inbound lane and an outbound lane, which is the opposite lane of the inbound lane. The blade has a back surface facing the same direction as an inbound traveling direction and a front surface facing the same direction as an outbound traveling direction. The back surface has a concave part that is concave in the same direction as the outbound traveling direction in order to change wind blowing from the outbound lane into wind having a component of the inbound traveling direction. The front surface has a concave part that is concave in the same direction as the inbound traveling direction in order to change wind blowing from the inbound lane into wind having a component of the outbound traveling direction.

A system includes a glare-blocking member including a left recess, a right recess, and a rail including, a left lateral portion including a left protrusion configured to mate with the left recess of the glare-blocking member, a right lateral portion including a right protrusion configured to mate with the right recess of the glare-blocking member, and a projecting contour disposed between the left and right lateral portions, wherein an apex of the projecting contour is disposed farther from a line passing through lower edge portions of the rail than is either the left or the right protrusion
