Siouxland Veterans Memorial Bridge
Officially opened in January 1981, the Siouxland Veterans Memorial Bridge replaced the nearly century-old "Combination Bridge". The bridge was originally built to serve railroad, wagon, and pedestrian traffic. It was later converted to carry streetcars and automobiles.

The Siouxland Veterans Memorial Bridge is a steel tied arch suspended deck design and spans 1,502 feet over the Missouri River. The bridge carries roughly 28,600 vehicles daily to and from Sioux City, Iowa and South Sioux City, Nebraska.

Did you know? During a routine inspection in May 1982, engineers found a 32-inch fracture on the downstream tie girder. The crack prompted an immediate closure of the bridge. While it was originally estimated that repairs would be completed in six days, the bridge did not fully reopen to traffic until a full year later.

January 1993. One year later the Argosy company of Illinois purchased the rights to the boat and brought in their own larger craft to the Missouri River. This casino, originally dubbed the "Belle of Sioux City" and later just the "Argosy", was operational until 2014. During the peak of its popularity, the facility employed over 300 people and could host over 1,000 passengers.

What happened to the riverboat?
In October 2014, the Argosy Casino Riverboat was moved to Wood River, Illinois. The boat was docked in Illinois for four years until 2018 when it was moved to western India! Once removed, the City of Sioux City sought community input and formed a steering committee to revitalize the area into public park space.
