The "Transportation Revolution" refers to a period in the early 19th century when significant advancements in transportation transformed how people and goods moved. Key developments included the introduction of the steam engine, which powered trains and boats, and the expansion of roads and canals. These innovations made travel faster and more efficient, connecting distant regions and facilitating trade. This revolution also led to the growth of cities and changes in society. The construction of railroads, such as the Baltimore and Ohio Railroad, and the use of canals allowed for easier access to markets. As a result, the economy flourished, and the movement of people increased, shaping modern transportation systems.
