Flexible elongate web structures with reflective faces are fixed on opposing ends of a support arm which is centrally mounted over a highway barrier. Appropriate geometric structure and material selection provide a non-destructive bending response for the respective web structures during vehicle impact and provide for restoration to original orientation. The support or mounting arm is formed of polymer material having sufficient rigidity to support the web structure during static conditions and sufficient compliance and flexibility to bend and twist during the vehicle impact.

A median barrier delineator comprising: a. a pair of elongate webs, each having a geometric structure which deforms upon impact by a moving object to develop a nondestructive bending response, with subsequent restoration to its approximate original orientation and configuration; b. an elongate mounting arm attached at each end thereof to one of the elongate webs such that the mounting arm supports the elongate web pair in an upright orientation, and has sufficient length such that the attached webs are displaced a sufficient distance away from the median barrier to permit the web to freely contort about the mounting arm upon occurrence of said impact by the moving object, said arm being comprised of materials having sufficient rigidity to support said web pair during static conditions, but sufficient contortional compliance and flexibility to bend and twist during dynamic conditions resulting from the impact; and c. attachment means disposed centrally along the mounting arm for coupling the arm with mounted webs across said median barrier in an upright orientation with respect to sidewalls of the median barrier.
