March 12, 2015 will mark the 87th anniversary of the collapse of the St Francis Dam in San Francisquito Canyon, Los Angeles County, California. The collapse occurred just before midnight on March 12, 1928. It is still California’s second largest disaster in terms of lives lost. Approximately 500 people died in the ensuing flood which flowed to the ocean near Oxnard, CA along the Santa Clara River Valley. Only the 1906 San Francisco Earthquake and Fire exceeds the number.

Between 1970 and 1979, State Highway 67 was realigned between Archie Moore Rd and Mussey Grade Rd. This realignment left two sections of paving with white striping intact. Most likely, the paving dates to around 1948 when State 67 was realigned around San Vicente Reservoir.

At Kay Dee Ln, only a section remains intact.
