I-579's roots go back to 1966 when the short {{Convert|0.7|mi|km|adj=on}} Crosstown Boulevard from the Boulevard of the Allies (PA&nbsp;885) to Bigelow Boulevard (PA&nbsp;380) was designated as '''Interstate 479''' ('''I-479''').

Despite the choice of number, its parent I-79 was only completed in certain areas; there would be no connection of the two routes until 1989. By 1971, with only little progression of I-79 near I-479's northern terminus and easy (but indirect) access to then-I-76 (now I-376 Parkway East) from the southern terminus, I-479 was renumbered as '''Interstate 876''' ('''I-876'''). 

This was renumbered again on October 2, 1972, as its current designation of I-579; in addition, I-79's designation from Pittsburgh to [[Robinson Township, Allegheny County, Pennsylvania|Robinson Township]] was "swapped" with I-279's segment south of the [[Ohio River]] from [[Pennsylvania Route 51|PA&nbsp;51]] to the Parkway West interchange.<ref name=1972news>{{cite news|title=Interstates Renumbered|url=https://www.newspapers.com/clip/15491728/interstates_redone_10272_february/|access-date=November 30, 2017|work=The Pittsburgh Press|date=February 24, 1972|page=8|via=[[Newspapers.com]]}} {{open access}}</ref> In 1989, both of I-79's auxiliary routes were finally connected with the openings of I-279 (Parkway North) from the Fort Duquesne Bridge/North Shore to its northern terminus at I-79 in Franklin Park and the Veterans Bridge which extended I-579 across the Allegheny River to its new northern terminus at I-279 in Pittsburgh's East Allegheny neighborhood.

In 2019, the I-579 Cap Urban Connector Project began in order to build a pedestrian park over I-579 with the goal of better connecting downtown to the [[Hill District (Pittsburgh)|Hill District]]. The project was completed in 2021 and the park opened to the public on November 22, 2021.<ref>{{cite web|title=I-579 Cap Urban Connector Project: Bridging a Critical Gap to Revitalize the Hill District|publisher=Pennsylvania Department of Transportation|url=http://www.i-579captiger.com/|access-date=August 23, 2020}}</ref><ref>{{cite web|title=I-579 Cap Urban Connector Project|url=http://www.pgh-sea.com/index.php?path=i5-ucp|publisher=[[Sports & Exhibition Authority of Pittsburgh and Allegheny County]]|access-date=August 23, 2020}}</ref><ref>{{cite news|first=Mark|last=Belko|title=Righting a wrong: New park over I-579 to reconnect Downtown and the Hill District|url=https://www.post-gazette.com/business/development/2019/06/14/new-park-over-I-579-to-bridge-Downtown-pittsburgh-Hill-District/stories/201906140069|work=[[Pittsburgh Post-Gazette]]|date=June 14, 2019|access-date=August 23, 2020}}</ref>
