Originally determined eligible by the Keeper of the National Register in the Caltrans 1985 Historic Metal Truss Bridges in California Thematic Resources study; continued eligibility was confirmed in the 2004 Caltrans Historic Bridge Inventory update: Metal Truss Bridges.
Burger Creek Bridge is a rare Whipple deck truss bridge. It is a variation of the Pratt truss bridge, but is unusual in that its diagonal members span across two panels of vertical members. The bridge is the only extant example of its kind in California. Furthermore, the bridge features the Phoenix Column, a hollow wrought-iron column consisting of four iron flanges riveted together at the corners. This innovative design provided greater strength and height. At the time of its evaluation, distinctive features also included its timber railing and timber deck. Between 2004 and 2006 the original timber railing was replaced with a metal railing.
Criterion Consideration (b) - Moved Property. Burger Creek Bridge (10C0109) was manufactured in 1888 in the Midwest by the Phoenix Bridge Company and was originally a railroad bridge. The bridge was relocated to Mendocino County and adapted to highway use in 1934. It is the only extant example of the Whipple deck truss in California.
