NPS Roads, Bridges, and Tunnels

The National Park Service Transportation Program is responsible for maintaining paved and gravel roads, bridges, and tunnels (see NPS Transportation System Characteristics PDF Format,1.5 MB), spread across all park units. The paved roads alone would stretch the distance between Washington, DC, and Los Angeles, Calif. This important infrastructure represents a Federal investment in excess of $30 billion dollars.

With inadequate funding, along with chronic inflation that continues to impact construction costs, road conditions In the National Parks have not been stabilized. Thus, the National Park Service faces a large backlog in maintenance projects.

The NPS Transportation Program's main goal is to minimize deterioration of transportation facilities using pavement and bridge management systems to assess transportation asset condition and aid in prioritization of projects.
