Rollins Dam

The Bear River Bridge was located in Nevada County, California, from 1908 to 1963, replacing an earlier wooden structure. When built over the Bear River, it was the highest railway bridge in the state. The bridge was built by the Nevada County Narrow Gauge Railroad, under the management of Sarah Kidder. From the surface of the water, at an average stage, up to the track was 200 feet (61 m). The total length was about 900 feet (270 m), and at the time of construction there were no approaches, the opposite banks being abrupt. The pier foundations were built of reinforced concrete, requiring more than 500 cubic yards. The piers and superstructure were of structural steel, of which about 500 tons were used. All the steel material was furnished by the American Bridge Company of San Francisco, and the constructing contractors were Shattuck & Edinger Construction Company, also of San Francisco. The total cost of the bridge was approximately US$70,000. The engineering involved much difficulty—principally due to the unusual height of the structure. At the beginning of the work the contractors stretched a 2.25 inch diameter steel cable from bank to bank more than 200 feet (61 m) above the Bear River, and 1,000 feet (300 m) long. By means of this cable all of the structural steel material required, as well as the concrete, were hoisted and conveyed by a trolley to the required point and lowered to the proper position. It took about six months to complete construction. Only a small force of men were employed and the work necessarily progressed rather slowly. The bridge was on a 1 mile (1.6 km) long cut-off which shortens the road 2 miles (3.2 km), and also eliminated two long wooden bridges, each 100 feet (30 m) high, and one 400 feet (120 m) tunnel. The bridge was taken down to make way for the Rollins Dam in 1963.

Long Ravine Trestle is a pair of deck plate girder railway bridges near Colfax, California. They carry the Union Pacific Railroad Roseville Subdivision over Long Ravine and Interstate 80, traversing the Sierra Nevada. The original crossing was a three-span Howe truss bridge with wooden trestle approaches, constructed as part of the first transcontinental railroad. The Nevada County Narrow Gauge Railroad was subsequently constructed under the bridge between 1875 and 1876. The trestle portions of the bridge were replaced with embankments by this time. The original wooden trestle was replaced with an iron structure in 1890. Southern Pacific double tracked the line and constructed the two modern bridges, completed in 1912 and 1913, to carry the rails. The southern span was retrofitted in the late 1958 to allow for the new U.S. Route 40 freeway to be routed underneath. The bridge is predominantly used for freight trains, but is utilized by the daily Amtrak California Zephyr.
