The Dubuque Freight House is a historic building located in Dubuque, Iowa, United States. Built by the Chicago, Burlington and Northern Railroad (CB&N) in 1901, this was the third and last freight house built by a railroad in the Ice Harbor area. The other two facilities were built by the Illinois Central Railroad (1872) and the Chicago, Milwaukee and St. Paul Railroad (1874). These other two railroads were older, larger, and monopolized the bridge and tunnel that crossed the Mississippi River. The CB&N was fortunate that their freight house was located along the water's edge in that the river boats could tie up next to the building and load and unload cargo, and the railroad put box cars on ferries that docked in the Ice Harbor. The Dubuque Boat and Boiler Works were headquartered on the west end of the facility for 20 years beginning in 1952. Founded in 1852 as the Iowa Iron Works, they provided engines, boilers and other equipment for river boats, and water craft for the United States Navy, United States Coast Guard, and the United States Army Corps of Engineers. The building was listed on the National Register of Historic Places in 1979. It is now a part of the National Mississippi River Museum & Aquarium.

Diamond Jo Boat Store and Office, also known as the Dubuque Tank Terminal Co. and Inland Molasses Co. Operations Office, is a historic building located in Dubuque, Iowa, United States. This is the last remaining structure in the city that is associated with the steamboat era on the Mississippi River. Several other buildings associated with this line were destroyed in a 1909 fire. This building housed the headquarters of the Diamond Jo Line from the mid-1880s until it was sold to the Streckfus Line in 1911. Originally headquartered in McGregor, Iowa, Joseph Reynolds started in the steamboat business after the American Civil War shipping wheat Minnesota and the Chicago and Northwestern railhead at Fulton, Illinois. In the last quarter of the 19th century the Diamond Jo Packet Line was one of the most active steamboat lines on the upper Mississippi. As railroads gradually took the freight business away from steamboats, Reynolds started to build passenger boats and he bought boats from other lines. The offices were located on the east end of the simple, two-story, brick building, and the rest was used for storage. The building was listed on the National Register of Historic Places in 1974. The structure resides at the corner of Jones and Water St. in Dubuque Iowa.

Dubuque station was a train station in Dubuque, Iowa. It originally served the Illinois Central Railroad. In 1917, the site was considered for creating a Union station in Dubuque. However, no such plan transpired and each railroad continued to use separate depots. Over the years, the station hosted the Illinois Central's Hawkeye, Iowan, and Land O'Corn trains. Passenger service ceased upon the formation of Amtrak in 1971, but resumed between Chicago and Dubuque in 1974 under the name Black Hawk. Service ceased on September 30, 1981. A proposed revival of the service, since cancelled, was to use the Dubuque Intermodal Transportation Center as its terminal.

Schroeder-Klein Grocery Company Warehouse, also known as the Shields & Bradley Block, is a historic building located in Dubuque, Iowa, United States. It was built to house the warehouse needs of the Schroeder-Kleine Grocer Company and the M.M. Walker Company, two of the most prominent wholesale food distributors in the upper Midwest at the turn of the 20th century. Local builders Shields & Bradley constructed the three-story warehouse in 1894 so that the two firms could operate independent of each other. When the two firms merged in 1921, the building became fully interconnected. It was used as a food distribution warehouse until 1959. Other commercial ventures that have been housed here have included beer and soda bottling and distribution, chemical production, overhead door sales, hair products retailer, and pet groomer. In addition to its commercial importance, the building is also considered a significant example of a late 19th century Romanesque Revival warehouse. This was one of several large warehouses built in that style during the same time period in the city, and it is one of few that is still extant. Elements typical of the style found in this building include its massive limestone base, limestone string courses, brick corbelling, and round-arch windows. The building was listed on the National Register of Historic Places in 2011.

The Port of Dubuque (also known as the Ice Harbor, 4th Street Peninsula, or the Riverfront) is the section of downtown Dubuque, Iowa, USA, that is immediately adjacent to 579.4 mile to the Mississippi River. The area was among the first areas settled in what became the City of Dubuque, and the State of Iowa. Historically, the area has been a center of heavy industry, but has recently seen extensive reinvestment and new construction. The area is now one of the main tourist destinations in Dubuque, as well as Iowa. The Port of Dubuque includes all of the area that lies north of the CCPR rail yards, south of East 9th Street and Dove Harbor, east of the CCPR/ICER railroad tracks, and west of the Mississippi River. It is divided into two main sections: the North Port and the South Port, which are separated by the Ice Harbor. The Port area is separated from Downtown Dubuque's central business district by a double set of railroad tracks and an expressway that carries U.S. highways 151 and 61. The North Port can be accessed via East 5th Street, or the East 3rd Street overpass, while the South Port is accessible from Jones Street, or Ice Harbor Drive—which connects the two ports together. As of 2006, all of the redevelopment in the area has occurred in the North Port, and the South Port remains largely industrial or underutilized. This may be due to the anticipated construction of a new Mississippi river bridge, which will be built in the near future, alongside the Julien Dubuque Bridge.
