Making the Impossible Possible

From the transcontinental railroad to the canals that forged America, national parks tell the story of transportation in America.  

The history of the National Park System is also inextricably linked to transportation. In the early part of the 20th century, the great railroads promoted parks in order to entice tourists to travel out west. The successful promotion of national parks and the advent of the automobile created a need for expanded access. Magnificently designed scenic roads and parkways have been central to defining visitor experiences by harmonizing with the environment and providing extraordinary views. 

Today, National Park Service transportation professionals protect park resources and provide access to millions of visitors each year by planning, implementing, and managing innovative transportation systems.
