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 was "swapped" with I-279's segment south of the Ohio River from PA 51 to the Parkway West interchange. 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.
