Of these structures 4794 were on the state highway system and 481on county roads. Groups of culverts were selected for inspection in all parts of thestate in order that the widest range in soils and climatic conditionsmight be included. When properly installed and maintained, the corrugated metal typeof culvert was found to be economical in most sections of the state.
