For almost 75 years, the Grand Avenue Viaduct (known today as the Gordon Drive Viaduct) has been a familiar feature of Sioux City's urban landscape. With the exception of bridges over the Mississippi River, the Grand Avenue Viaduct is Iowa's longest grade separation as well as its longest bridge. For nearly a mile, from the eastern suburbs west to the central business district, the viaduct carries Gordon Drive and the city route of U.S. 20 over the Floyd River valley, which includes the remnants of the city's famed stockyards and the South Bottoms neighborhood, as well as a maze of railroad tracks and the present channel of the Floyd River. Constructed in 1937 and known simply as "The Viaduct" to local residents, the massive structure is as fundamental to Sioux City as were its stockyards just a few decades ago.
