North Umpqua River Bridge
Description
The bridge at the Soda Springs Dam over the North Umpqua River is a pin-connected Pratt through truss. The pin-connected design would indicate the bridge was fabricated far earlier than its 1955 construction date. This bridge is more than likely a recycled bridge from another area and was placed it its current location in 1955 as part of the North Umpqua River Hydroelectric Project. The bridge is estimated to be built between 1900 and 1920.North Umpqua Hydroelectric Project is located in south central Oregon in a remote area of Douglas County, about 60 miles east of Roseburg. Constructed between 1947 and 1956, the eight hydroelectric developments use water primarily from the North Umpqua River and from two of its major tributaries, the Clearwater River and Fish Creek, to generate electricity.
