This paper draws on findings from a study of the full cost of highway deicing salt by a National Research Council committee. Cost estimates are presented for bridges, other highway components, and parking structures. Summation of the more reliable cost items, for which supporting data are dependable and relatively complete, suggests a national cost of $200 million to $500 million per year. Inclusion of cost items based heavily on committee judgment suggests a national cost of about $400 million to $900 million per year.
