Administrative History

This volume contains maps of urban area boundaries compiled by the district offices of the Department of Public Works (after 1967 the Department of Transportation) and submitted to the U.S. Public Roads Administration for approval. The Federal-Aid Highway Act of 1944 authorized special aid for highways lying within urban areas (defined as incorporated cities or villages of 5000 or more population plus surrounding unincorporated areas which were urbanized). State wishing to obtain this special highway aid had to have maps of the urban areas approved.
