Union Ave


The Union Avenue Historic Commercial District was placed on the  National Register on December 28, 1982.  The district consists of a group of business structures located to the northwest of the Arkansas River in Pueblo’s old business district. Of the original 87 properties that were within the boundaries, 70 contributed to the historic and architectural importance of the district.

The area developed quickly following the platting of South Pueblo in 1872, with the first brick buildings appearing in the early 1880’s. 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.

Photographs for these structures can be found at our National Landmarked Properties page.  You may also download a copy of the Union Avenue Historic District brochure .
