Interstate 579 (I-579) is a north–south Interstate Highway entirely within Pittsburgh, Pennsylvania. The highway is 2.73 miles (4.39 km) long. I-579 is also known as the Crosstown Boulevard since it crosses the backside of Downtown Pittsburgh.
The northern terminus of I-579 is at I-279 beyond the north end of the Veterans Bridge; the southern terminus splits to the Liberty Bridge southbound and Boulevard of the Allies eastbound, which leads to I-376 east. The intersection of I-579 and I-279 is in one direction only; northbound traffic on I-579 can proceed only northbound on I-279 while only southbound traffic on I-279 can exit onto I-579.
I-579 allows Liberty Bridge traffic easy access to I-279, and I-279 southbound traffic easier access to PPG Paints Arena, downtown, and eastern regions of the city, while I-279 southbound continues to Acrisure Stadium, PNC Park, and to westbound I-376 which leads to Pittsburgh International Airport.
