H. Pithie in 1894.","why_significant":"The nomination presents it as the oldest and first of many stone bridges built across Napa County. It was built with stone from the Wing Quarry and is described as structurally sound. It survived the 1906 earthquake undamaged and has served as a link to Chiles Valley, Pope Valley, Howell Mountain and nearby highways since 1894.","narrative":"Spanning the Napa River northeast of St. Helena, this triple-arch stone bridge carries Pope Street and has been in continuous use since 1894. R. H. Pithie designed and built it, using hewn stone from the Wing Quarry on Monticello Road. The bridge is 175 feet long and 18 feet wide between parapet walls, with walls two feet thick. It cost $14,500, and about $17,500 including the channel change and approaches. Built for horse-drawn traffic, it was not intended to let two vehicles pass at once. It is described as the oldest of Napa County's old bridges and the first of many stone bridges built there. It came through the 1906 earthquake unharmed, which the nomination credits to its craftsmanship. It still links St. Helena with Chiles Valley, Pope Valley, Howell Mountain, the Silverado Trail and Highways 128 and 29. The City of St. Helena owns it, and it was considered structurally sound.","period_of_significance":null,"architect_builder":"R. H.
