A section of the beltway between Pittsburgh International Airport/Interstate 376 and U.S. Route 22 opened to traffic in 2006. The new road has been designated as Pennsylvania Route 576. A section between U.S. 22 and I-79 is expected to be open by 2021, with the third section being between I-79 and a section of the Mon–Fayette Expressway near Finleyville, Pennsylvania just south of the current northern terminus. In order to provide access to certain interchanges within the Uniontown-to-Brownsville project, the PTC had to build several toll-free connectors, the most notable of which extended a four-lane section of U.S. Route 40 near Brownsville, eliminating a forty-year-old freeway stub in the process. Near Uniontown, the PTC constructed a four-lane road, named Northgate Highway, between U.S. Route 40 and Pennsylvania Route 51. In addition, a new connector was added to join Telegraph Road and Bull Run Road in Luzerne Township, potentially opening many acres of land to future development. The aforementioned access roads were necessary to provide access to exits 22, 15, and 26 respectively, but these routes were also designed to improve local connections and accommodate any future economic development in the interchanges' immediate vicinity.
