Abstract: A roadway barrier includes: (i) a longitudinally corrugated rail defining a longitudinal trough between longitudinal ridges, which rail in the region of the trough, defines an aperture: (ii) a reflector comprising: (a) a substantially V-shaped panel with a reflective surface, the panel defining a spine and a pair of arms that diverge from the spine, and the panel arms being resiliently movable between a neutral condition and a splayed condition; (b) a shaft extending from the spine of the panel, between the panel arms, wherein each panel arm is substantially planar and tapers in height from the spine towards its free end; and (c) a connector for securing to the reflector shaft.
