​Engineering Directives and Standards Manual

The reasons for establishing this Engineering Directives and Standards Manual are to: (a) simplify the directives system; (b) eliminate proliferation and supplementation of basic directives; and (c) consolidate for ease of reference all directives containing policies, procedures, standards, and guides relating to the administration of the Highway Program.
