The bridge was opened in 1957 to alleviate traffic concerns on the older Fairfax Bridge. The Platte Purchase Bridge carries northbound traffic, while the older span carries southbound traffic.

In 2013 plans were announced for replacement of both the Platte Purchase Bridge and the Fairfax Bridge. When the latter closed on October 31, 2014, the Platte Purchase span was restriped to handle two-way traffic.[1] The Platte Purchase bridge was set for demolition in late 2016 when the new bridge opened.[2] The first detonation occurred on the morning of Friday, December 9, 2016, and the rest of the bridge was demolished on Thursday, January 12, 2017.
