The steel suspended tied-arch bridge has a main span of with anchor arms. The suspended portion of roadway comprises and is wide, carrying four lanes with a median divider strip at a height of above mean water level. The 1950 bridge replaced a bridge built in 1908 at the same location. The new bridge was recognized by the American Institute of Steel Construction as the most beautiful bridge of 1950 for spans over in length.
The bridge's engineer was R. W. Finke. The contractor was the General Construction Company of Seattle, using steel fabricated by the American Bridge Company. The bridge rests on two concrete piers in the river, with the central arch between them, and cantilever spans extending to concrete abutments high on the riverbanks.〔 Now named the Senator George Sellar Bridge after a Washington state senator, the bridge carries Washington State Route 285 since the construction of the Richard Odabashian Bridge for Route 2 farther north. An additional lane was added in 2009-2010. The bridge was placed on the National Register of Historic Places on May 24, 1995.〔
