First Avenue Bridge

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.

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.

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.
