What you should know about The Old Road.
The Old Road is best known for preserving portions of the historic transportation route that linked Los Angeles with the San Joaquin Valley before construction of Interstate 5, following alignments associated with U.S. Route 99, among California's principal highways between 1926 and 1964. The corridor occupies land formerly included within Rancho San Francisco, the approximately 48,612-acre Mexican land grant awarded in 1839 to Antonio del Valle, before nineteenth-century wagon routes, stage lines, and later automobile highways established the area's importance as a gateway through the Newhall Pass and northern Los Angeles County. Nearby Castaic Lake State Recreation Area, opened in 1974 following completion of Castaic Dam in 1973, introduced one of California's largest State Water Project reservoirs while expanding recreation, boating, fishing, and water management across the Upper Santa Clarita Valley. The Old Road also benefits from continuing investment by Caltrans, the Los Angeles County Department of Public Works, the California Department of Water Resources, and the County of Los Angeles, supporting roadway improvements, bridge maintenance, drainage systems, transportation safety, and long-term infrastructure planning.
Pyramid Lake, created by completion of Pyramid Dam in 1972, stores imported water delivered through the California Aqueduct, forming a critical component of the California State Water Project serving communities throughout Southern California. Castaic Union School District, established in 1890, operates elementary schools serving the area's expanding residential population while contributing to the community's educational development. The Ridge Route, completed in 1915, crossed nearby mountain terrain as California's first paved highway connecting Los Angeles with the San Joaquin Valley, preserving an important chapter in the state's transportation history closely associated with The Old Road. Angeles National Forest, established in 1908, extends across much of the surrounding mountain landscape, supporting watershed protection, habitat conservation, wildfire management, and outdoor recreation throughout northern Los Angeles County.
