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. With the pacification of the Indian threat in Illinois, the U.S. Government ceased operations at Fort Armstrong and the U.S. Army abandoned the frontier fort in 1836.

United States Housing Corporation (U.S.H.C.) Historic District is a nationally recognized historic district located in Rock Island, Illinois, United States. It was listed on the National Register of Historic Places in 2024. The historic district is made up of two discontinuous units and it includes 393 resources, which consists of 206 contributing buildings and 187 non-contributing buildings. The houses that make up this district were part of 638 houses constructed between 1918 and 1919 by the United States Housing Corporation (U.S.H.C.) in the Tri-Cities, now known as the Quad Cities. The local project area was referred to as the Rock Island District. At the time, there was a housing shortage in the area and a significant number of new workers were needed at the Rock Island Arsenal and other area manufacturers to produce supplies and munitions for the United States Army during World War I. St. Louis landscape architect George Kessler was hired to plan the Rock Island development. Rock Island contractor Henry W. Horst built the houses designed by the local architectural firm of Cervin and Horn. The houses were both single-family detached and semi-detached houses. The Tri-Cities housing committee favored permanent housing over temporary, and the houses were designed in styles that were popular at the time. The project came to an early end when the Armistice to end the war was signed in November 1918. The project in the city of Rock Island was far enough along that it was completed in full. It was one of the few U.S.H.C. projects in the country to be completed. Of the 900 houses planned in the Rock Island District, 110 houses were completed in neighboring Moline, 111 were completed in East Moline, 200 were completed in Rock Island, and 217 were completed across the Mississippi River in Davenport, Iowa. The houses in Iowa were designed by the architectural firm of Temple & Burrows and built by Central Engineering Company, both from Davenport. Initially, the houses were rented. The Rock Island District houses were the first U.S.H.C. houses to be sold, and this local sale set a pattern for the sale of the houses built in the rest of the country.

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.
