On October 16, 1974, two pieces of I-79 were opened: the other two lanes of the from exit 155 to the state line, and between exits 117 (Anmoore) and 125 (north of Bridgeport).
In late 2008, the "missing ramps" of the I-79/I-376 interchange (PA 60 was designated as the route for southbound traffic seeking to go to Pittsburgh International Airport & airport traffic seeking to go northbound on I-79) were completed [REF].
