The 2014 National Transportation Atlas Database, which has GIS data for transportation, was released last week. It is available for free on DVD from the U.S. Department of Transportation.

The DVD is a set of nationwide geographic databases of transportation facilities, transportation networks, and associated infrastructure. These datasets include spatial information for transportation modal networks and intermodal terminals, as well as the related attribute information for these features. Metadata documentation, as prescribed by the Federal Geographic Data Committee, is also provided for each database.
