The Kettle Falls Bridges is the collective name for a pair of steel cantilever bridges carrying State Route 20/U.S. Route 395 and the BNSF Railway across the Columbia River at Kettle Falls, Washington. The south bridge carries motor vehicle traffic while the similar northern span is used for rail. ==History== On May 3, 1941, the Columbia River road bridge at Kettle Falls opened to traffic. Both bridges were constructed to replace bridges flooded by waters rising behind the Grand Coulee Dam to form Franklin D. Roosevelt Lake. The bridges are historically significant because they feature the longest central spans of any highway bridge built in Washington state during the 1940s. In 1995 the steel truss road bridge was added to the National Register of Historic Places.
