OUR NATION’S TRANSPORTATION INFRASTRUCTURE
1
• Connects
– cities to suburbs, factories to markets, ports to warehouses,
workers to work places, children to schools
• Supports other critical infrastructure, e.g., energy
• Is enormous,
– 4 million miles of roads
– 175,000 miles of rail lines
– 12,000 miles of navigable inland waterways
– 1.7 million miles of oil and gas pipelines
Transportation infrastructure moves people and goods,
and supports nation’s economy
2
• Carries 254 million vehicles
• Provides mobility to 15 million Americans who do not own a
vehicle
• Moves 16 billion tons of goods
• Pipelines transport 5.4 billion barrels of petroleum
• Supports 10 million airline flights, carrying 800 million
passengers and 44 billion tons of freight among commercial
service 600 airports.
• The entire transportation system accounts for nearly 9 percent
of U. S. gross domestic product.

transportation equipment (such as a state DOT’s operation center’s computers).
Amount of freight moved on highways, railroads,
and inland waterways: 2007

Measured by weight, freight movements on the U.S. transportation
system decreased by 13% from 2007 to 2009
