Fort Armstrong (1816–1836), was one of a chain of western frontier defenses which the United States erected after the War of 1812. It was located at the foot of Rock Island, in the Mississippi River near the present-day Quad Cities of Illinois and Iowa. It was five miles from the principal Sac and Fox village on Rock River in Illinois. Of stone and timber construction, 300 feet square, the fort was begun in May 1816 and completed the following year. In 1832, the U.S. Army used the fort as a military headquarters during the Black Hawk War. It was normally garrisoned by two companies of United States Army regulars.

The Government Bridge or Arsenal Bridge spans the Mississippi River, connecting Rock Island, Illinois and Davenport, Iowa. The Iowa Interstate Railroad uses the upper deck of the bridge for its ex-Chicago and Rock Island Railroad route between Council Bluffs, Iowa and Chicago, Illinois. The lower deck carries automobile traffic between the two cities. It is located near Upper Mississippi Mile Marker 483, adjacent to the Mississippi River Lock and Dam No. 15. The current structure (which was completed in 1896) is the fourth at this location. The bridges all were built with a swing section to accommodate traffic navigating the river. The first Rock Island Bridge, which was finished in 1856, was the first railroad bridge across the Mississippi. The bridge was 1,582 feet (482 m) long, and the draw-span was 285 feet (87 m). It was located upstream from the current bridge. It was a threat to the South (which sought to create a southern rail route to the Pacific) and to St. Louis, whose steamboats faced competition from Chicago's railroads. The Effie Afton struck the bridge weeks after it opened, and steamboat companies brought lawsuits. It was repaired, but was replaced in 1866 by the a wooden structure in the same location. In 1868, the second bridge was damaged by an ice storm and a tornado; however, construction crews repaired and reopened the bridge. It was replaced in 1872 by a twin double-deck bridge. The third bridge, 366 ft (112 m) long, was built downstream near the Rock Island shore in the present location. During the 1880s, the bridge accommodated horse-drawn trolley cars. Electric trolleys ran on the current bridge until 1940.
