While the highway was built the buildings were spared. The fifth building is non-contributing as are three structures. This is primarily a commercial area located immediately south of the central business district. Originally, this is where the city's commercial district was located because of its proximity to the ferry and riverboat landings.

The buildings are all constructed in brick and are between three and four stories tall. It is considered to be the "largest concentration of significant nineteenth-century commercial architecture" in Dubuque.
