Zipped .shp files are available for downloading:

Problems downloading? Try the following:

If space allows, the last two letters in the file name represent the feature type: ln = line, pt = point, py = polygon.

Scales for files vary. These scales are unitless. Be sure to note the file scales before combining.

The scale of the file may be included in the name, if space allows or if known: 24k = 1:24,000; 100k = 1:100,000; 250k = 1:250,000; 1m = 1:1,000,000; 2m = 1:2,000,000

No claims are made to the accuracy of the data or to the suitability of the data to a particular use.
