The current Green Belt begins eastbound on Camp Horne Road at PA 65 in Emsworth and originally terminated before the Rankin Bridge in Rankin. This was later extended to its current southeastern terminus at PA 148 and the Yellow Belt in McKeesport, giving the Green Belt the distinctions of being the only one in the system to cross the same river (Monongahela) twice and terminate at another belt route. In its path around the city, the belt crosses or joins PA 8 (at its northernmost point in Hampton Township), PA 28, PA 65, PA 130, PA 148, and PA 837. It also briefly joins US 19 in Ross Township.
