Scope and Content Note

The maps in this volume vary in format and content. Some were evidently drafted in the district offices, while others are U.S. Geological Survey 7.5 minute series quadrangle maps modified in the 1970's for use by the New York State Department of Transportation. The latter show all Federal-Aid highways systems: Interstate ('I'), Federal-Aid Primary ('P'), Federal Aid Secondary ('S'), and Federal Aid-Urban ('U'). Older maps show only primary, secondary, and urban routes. Every map, whatever its date, is stamped "approved" by the U.S. Public Roads Administration or Bureau of Public Roads. The maps are arranged alphabetically by urban area name under the D.P.W. (now D.O.T.) district in which an area is located. Earlier maps, showing urban area boundaries that were later revised, have been removed and presumably destroyed.
