|November 2015 (39.66161, -120.96432) Port Wine Road Bridges|
The bridges cross Slate Creek on the border between Sierra and Plumas Counties. The creek has a rocky obstruction in the middle that allowed two short bridges (instead of one longer bridge) to be built. When I visited in November of 2015 the creek was only flowing in the deep channel under Port Wine Road Bridge #2 (this was the same as when Craig Philpott visited the site in August 2010).
The name Port Wine came from an abandoned mining town that was formed (but soon abandoned) during the Gold Rush of the 1850s. Since the bridges were built many years later, they may have replaced earlier bridges across Slate Creek. This area (the North Yuba Watershed) has many ghost towns and abandoned mines dotting the landscape. Cemeteries, mine shafts, and building foundations still remain. Today, the town of La Porte is the largest remaining community from that time. It had a population of 10,000 people in the 1880s, a population of 43 in 2000, and a population of 26 in 2010.
