Posted by Secretary of Transportation Elaine Chao The US Department of Transportation (U.S. DOT) plays an important role in maintaining and improving the safety and efficiency of our nation's transportation infrastructure. This includes highways, bridges, tunnels, railways, airports, air traffic control, seaports, mass transit systems and pipelines. Our infrastructure is the backbone of our economy, making it possible to move people, goods, services and raw materials safely from our homes, factories, farms, and mines to and from destinations throughout our nation, and across the world. America's transportation infrastructure underpins our world-class economy and is a key factor in productivity growth, which has provided good jobs for millions of hard working Americans and a standard of living that is the envy of the world. And while our transportation infrastructure has given us unprecedented mobility for many years, it is increasingly in need of repair and refurbishment. Another challenge facing the transportation infrastructure is how to incorporate new technology and innovations, including drones and autonomous vehicles.
