1990 National Transportation Atlas

The 1990 National Transportation Atlas provides a detailed overview of transportation networks in the United States, including roads, railroads, air routes, and waterways at that time. It maps the infrastructure used for moving people and goods across the country, helping planners, policymakers, and researchers analyze transportation systems and their connectivity. The atlas offers visual and statistical information to understand how transportation networks support economic activity, regional development, and national mobility, serving as a foundational reference for transportation planning and management during that period.
