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.

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.

Kingston was established on the west bank of the river in 1852, and it was annexed by Cedar Rapids in 1870. The streets were laid out parallel and perpendicular to the river, which flowed from the northwest to the southeast. The Chicago, Iowa & Nebraska Railway, later the Chicago & North Western Railway, was the prominent railroad on the west side of town. The first bridge across the river at Third Avenue was built in 1871. The current bridge was completed in 1912. Prior to a bridge, Rapid City and Kingston were connected by a ferry operated by David W. King, the founder of Kingston. Initially residential, Third Avenue west of the river became increasingly commercial in the 1880s. The buildings that make up the historic district date from 1909 to 1942, and are representative of the various architectural styles and vernacular building forms that were popular during this time period.
