Carneros Creek Bridge is a stone arch bridge located on Old Sonoma Road southeast of Napa, California. The single-span, earth-filled closed-spandrel masonry arch structure retains its 1896 historic integrity, even after being widened in 1914. The bridge exemplifies how the availability of high-quality local building stone, combined with the craftsmanship of skilled stonemasons, contributed to the many enduring stone buildings and bridges that remain throughout Napa County. - AsNotedIn
