The cushioned cover for traffic structures comprises various embodiments configured for installation over concrete traffic barriers (e.g., “Jersey walls,” etc.) or about vertical columns, posts, stanchions, etc., e.g., bridge support columns. The cover includes inner and outer layers formed of rubber, preferably using recycled tire material. A medial layer includes additional resilience. In one embodiment, the medial layer includes a plurality of closely spaced hemispherical elements, preferably formed of highly resilient polybutadiene material. In another embodiment, the center layer includes a plurality of closely spaced, pneumatically interconnected inflatable hemispheres. The traffic barrier covers may include planter box receptacles set into their upper surfaces when installed, and/or solar cells set into their upper surfaces to charge a storage battery for powering lighting set into the sides of the cover. Tread patterns may be provided in the outer surfaces of the traffic barrier covers.
