Huntingdon’s boundaries started at the mouth of Brush Run, where it emptied into Brush Creek. The area is approximately 26 square miles (67 km2), with the Township maintaining about 125 miles (200 km)of roads. If these roads were placed end-to-end, they would stretch from North Huntingdon to Cleveland, Ohio. The boundaries, following along Byerly’s Path to Braddock Road, continued to the lines that mark Mount Pleasant, Tyrone, and Pitt Townships. Huntingdon Township was later divided into the townships North Huntingdon, East Huntingdon, South Huntingdon, and Sewickley. Around this same time, Westmoreland County, where North Huntingdon is located, became the townships of Fairfield, Donegal, Mount Pleasant, Hempfield, Pitt, Tyrone, Springhill, Menallen, Rostraver, and Armstrong.
