Calaveras County, California Bridges: Murphys Grade Road UC

May 2013 (38.08417 Degrees, -120.54333 Degrees) Murphys Grade Road UC
Today's photo shows Murphys Grade Road UC (30 0054) with the Penstock Bridge behind it. Murphys is a very charming old mining town and the road under the bridge goes there. The bridge is another cast-in-place prestressed concrete box girder structure. The National Bridge Inventory calls it a segmental box girder, but I doubt if it was segmentally constructed. It looks like it was built on forms supported on falsework.
