Abstract
A culvert to ditch transitioning device for lining a ditch proximate to an end of a culvert includes an end panel, which has an orifice positioned therein, and a pair of side panels. A terminal segment of the culvert, which extends into the ditch, can be inserted through the orifice so that a first face of the end panel is in substantial abutment with an end embankment of the ditch. Each side panel is coupled to a respective opposed end of the end panel and extends substantially perpendicularly therefrom. The pair of the side panels lines side embankments of the ditch, proximate to the end embankment. The end embankment and the lined portions of the side embankments thus no longer require lawn care, such as mowing, trimming, and weeding.
