Abstract: A highway barricade which has an appearance similar to that of a large steel drum is formed of an organic polymer. The sidewalls of the barricade are slightly tapered to permit the nesting together of a plurality of similar units, and the base portion thereof is provided with weighting means to permit it to withstand normal forces encountered in highway situations. Visibility of the device is enhanced by incorporating fluorescent, phosphorescent and/or reflective materials in the polymer; by providing faceted surfaces; and/or by locating a light source inside a translucent barricade.
