Crossroads Mall opened on March 14, 1963 with 394,000 leasable square feet for retail stores, surrounded by open-air parking.
Anchor stores included J. C. Penney and Montgomery Ward, as well as a Randall Shop, the small-format version of The Denver Dry Goods Company.
A 1983 remodeling and expansion doubled the size of the mall and included the addition of a food court and another anchor store, May D&F (later renamed Foley's and, still later, Macy's).
In September 1997, Montgomery Ward closed its store at Crossroads Mall; aside from a short stint as Gart Sports, this space would remain vacant until demolition.
Plans were submitted to the city to tear down Crossroads Mall and create a new retail district, dubbed "Twenty Ninth Street".
Unlike the indoor design of the Crossroads Mall, the new Twenty Ninth Street retail district is an outdoor shopping neighborhood.
