U.S. transportation infrastructure includes the systems and facilities that enable the movement of people and goods across the country. This encompasses a vast network of highways, railroads, airports, and ports, which are essential for economic activity and connectivity. Maintaining and improving this infrastructure is crucial for safety and efficiency. The Federal Highway Administration and Federal Aviation Administration oversee many aspects of these systems, ensuring they meet the needs of a growing population and evolving technology. Investments in public transit and bicycle lanes are also part of efforts to create a more sustainable transportation network.
