The waterway transportation system supports urban expansion and infrastructure development in U.S. cities along rivers.

The waterway transportation system plays a key role in the development of U.S. cities along rivers by promoting urban expansion and infrastructure growth. Rivers serve as vital trade routes, facilitating the movement of goods and attracting businesses to waterfront areas. This economic activity drives the development of ports, roads, bridges, and commercial centers, transforming these cities into thriving hubs for industry and commerce. As cities grow, they attract more population and investment, creating jobs and enhancing local economies. The presence of waterways encourages the growth of infrastructure that supports both urban living and industrial productivity, making these cities integral to national trade.
