At the time of its nomination it consisted of 60 resources, which included 46 contributing buildings, one contributing structure, 12 non-contributing buildings, and one non-contributing structure. Cedar Rapids was platted on the east bank of the Cedar River as Rapids City in 1841, and it was incorporated under the same name in 1849. Kingston was established on the west bank of the river in 1852. The two smaller communities consolidated in 1870 as Cedar Rapids. The streets were laid out parallel and perpendicular to the river, which flowed from the northwest to the southeast. The Chicago, Iowa and Nebraska Railroad was the first to arrive in the community in 1859 and the tracks were laid on Fourth Street on the eastern edge of the central business district. The first bridge across the river was built at Third Avenue in 1871. The first commercial buildings in this area were log and wood-frame construction. After the American Civil War they began to be replaced by more substantial masonry structures. The buildings that make up the historic district date from 1880 to 1965, and are representative of the various architectural styles and vernacular building forms that were popular during this time period. While they differ in height and historic use, the buildings all feature masonry facades, ground-floor storefronts, and uniform alignment that creates a uniform street wall. The buildings have housed a variety of commercial functions that include retail, office buildings, banking, post office, public library, industrial, saloon/restaurant, theater, hotel, and a social hall. The Fourth Street Railroad Corridor is the contributing structure, and a parking garage is the non-contributing structure.

The Highwater Rock is located in the Cedar River near downtown Cedar Rapids, Iowa, United States. It is a large granite boulder in the rapids in the eastern half of the river. Its height depends on the river level. It can be 3 feet (0.91 m) to 4 feet (1.2 m) above the water level in low water, or submerged in high water. It was used to gauge the river depth from the 1840s to the close of river navigation in the mid-1860s. In the early days, people could cross the river at the rapids on horseback, on foot, or by wagon and buggy. They would use the rock to determine if it was safe for them to cross. After David W. King began ferry service in 1848 and a toll bridge was built, people would use the rock to determine if the water was low enough to cross the river and avoid paying the tolls. King would use the rock to determine the amount of cargo he could carry or if he could run the ferry at all. After steam navigation was established on the river the steamer pilots would use the rock to determine if they could continue past the rapids. Railroads severely curtailed the use of steamboats on the Cedar River, and in 1870 the United States Congress declared the river was not navigable above Columbus Junction, which is well below Cedar Rapids. This put an end to water transportation on this part of the river, and the usefulness of the rock. It was listed on the National Register of Historic Places in 1977.

The First Avenue Bridge is a historic structure located in downtown Cedar Rapids, Iowa, United States. It carries U.S. Route 151 for 697 feet (212 m) over the Cedar River. The original six-span concrete arch structure was completed in 1920 for $420,000. It was designed by Marsh Engineering Company and built by Koss Construction Co., both of Des Moines. Consulting engineer Ned L. Ashton of Iowa City designed the 1960s remodel. He had all of the concrete work above the original arches torn out and the bridge rebuilt as an open-spandrel structure. The rebuild also included a wider deck to accommodate increased traffic and aluminum railings. While the bridge's original structural integrity has been compromised, this is the first notable concrete spandrel arch reconstruction in Iowa and possibly in the country. The bridge was listed on the National Register of Historic Places in 1998.

May's Island (or Mays Island) is a small island on the Cedar River, in Cedar Rapids, Iowa. Functioning as a civic center much like the Île de la Cité, it is the site of the Memorial Building (the city hall), the Linn County Courthouse, and the county jail. The island plus an adjacent block was listed as a historic district on the National Register of Historic Places in 1978.The island and all of its buildings were devastated by the 2008 flood of the Cedar River, with water reaching above the first floors. Until the 2008 flood, the concentration of local and county government on the island served to unify the city on both sides. The Memorial Building was designed by Hunter & Hatton, architects of Cedar Rapids. The Beaux Arts-style Linn County Courthouse was designed by Joseph Royer, of Urbana, as was the county jail. The building masses are long and narrow, like the island itself. The buildings face each other, creating an "insular quality".The concentration of government services extends to the east bank, where the Federal government is located, to the east of the Memorial Building, in the Beaux Arts-style Federal Building, whose design is credited to the Office of the Supervising Architect under James A. Wetmore. Its block, from 1st Avenue north to 2nd Avenue, from 1st Street west to the river, is also included in the historic district. This makes a total of four contributing buildings in the district.
