摘要

The U.S. Department of the Interior's National Park Service (NPS) is responsible for managing and maintaining nearly 5,000 miles (8,047 kilometers) of paved roads and parkways across more than 250 properties nationwide. Many of the scenic roads traversing the country's national parks were constructed by the Civilian Conservation Corps during the 1930s and are beginning to show their age. So too are the retaining walls and other support structures that secure, protect, uphold, carry, or otherwise convey these roads across challenging terrains. Unsung heroes among roadway infrastructure, these walls and other structural elements hold historic significance for NPS, and many have been preserved and rehabilitated over the years to meet modern traffic and safety requirements.
