A culvert end for a culvert comprises a culvert body and a brow. The culvert body has an upper section and an outer end that defines an opening. One or more structural weaknesses are formed in the culvert body. The one or more structural weaknesses are configured to allow the partial collapse of the upper section of the culvert body when the culvert end is subjected to a sudden end on force caused by a vehicle impacting against the outer end of the culvert body and to create a transitioning surface that enables the impacting vehicle to ride over the outer end of the culvert body. The brow is formed at the outer end of the culvert body and configured to initiate the partial collapse of the upper section when the brow is engaged by the impacting vehicle. |
