Union Avenue Historic Commercial District

The area developed quickly following the platting of South Pueblo in 1872, with the first brick buildings appearing in the early 1880s.  Originally a wholesale and warehouse district associated with the Denver and Rio Grande Railroad, Union Avenue experienced a major flooding of the Arkansas River in June 1921.
