Louis Brandeis, Missouri Pacific Company v. Western Crawford Road Improvement District…
“ A state may defray the cost of constructing a highway, in whole or in part, by means of a special assessment upon property specially benefited thereby. But it is not obliged to do so. Road building is a public purpose which may by effected by general taxation. The cost may be defrayed out of state funds, or a tax district may be created to meet the authorized outlay. The preliminary inquiry whether it is desirable to construct the road, is one in which all landowners within the district are interested. ”
