The current Orange Belt runs through the northern, eastern, southern, and western sections of the county, connecting four county parks (including South Park and North Park) and the Pittsburgh International Airport. It stretches from its southwestern terminus at PA 88 in Bethel Park northwest to Moon Township and Sewickley , then northeast to Richland Township and West Deer Township, southeast to Plum and Monroeville , and finally southwest to its southeastern terminus at PA 51 in Elizabeth. Much of the route was previously rural, though suburban sprawl has placed it in many prominent commercial corridors.
