Explore South Fayette, Pennsylvania, with this interactive street and satellite map.
This page also offers TOPO MAPS — the official USGS topographic sheets — plus USGS aerial imagery, a labelled USNG grid overlay, a distance and bearing tool, and a GPS grid-reference readout. See How to Use This Map below.
This interactive map shows the street layout and satellite imagery for South Fayette, Pennsylvania. Use the Map and Satellite buttons above to switch between street map and aerial imagery views. Use the + and − buttons to zoom in or out, or scroll your mouse wheel while holding the Control key to zoom. On a touchscreen, use a two-finger pinch gesture. Drag the map to pan to any area of Pennsylvania or beyond.
Click ⛶ Fullscreen to expand the map to fill your screen. To return to the normal page view, press the Escape key, click the ✕ Exit Fullscreen button that appears above the map, or on a mobile device tap the back button (Android) or the close icon (iOS).
TOPO MAPS — NEW. Click the green 🔍 Search Maps button below the map to open a second map with a Base map row offering three choices. OSM is the standard OpenStreetMap street map. Topo shows the official USGS topographic maps from The National Map — contours, hydrography, land cover and shaded relief, the same mapping used for hiking, hunting and back-country navigation in the Adirondacks, the Catskills and the Finger Lakes. Imagery shows USGS aerial photography, mostly 1-metre NAIP. The search box finds any US town, county or landmark by name, so you are not limited to South Fayette.
Reading the map like a paper quad. Click Grid to overlay the U.S. National Grid (USNG), labelled along the edges exactly as a printed topographic sheet is — at normal zoom the squares are one kilometre across, so you can read a six-figure grid reference by eye and judge distance directly off the map. Click Measure, then tap two points, to get the distance between them together with the grid bearing in degrees and mils, the true bearing, and the magnetic bearing to set on a compass.
Click 📍 My position to take a single GPS reading from your device. It marks where you are and reports your position as a USNG grid reference as well as plain latitude and longitude — USNG being the format FEMA and US search and rescue teams work from — with a Copy position button so you can paste it straight into a text message. It takes one reading and stops, rather than tracking continuously, to conserve your battery. Note that map tiles need cell coverage, but a GPS reading does not — your coordinates stay correct even where the map itself cannot load.

South Fayette reveals itself as a landscape defined by the persistent, rhythmic flow of Dolphin Run as it carves a path through the earth. It lies 6.1 miles west of Mount Lebanon, PA (from Mount Lebanon, PA: bearing 272°T), and is situated 6.9 miles west-northwest of Bethel Park. The terrain unfolds across a series of broad, elevated ridges that separate the Mohawk Valley from the surrounding expanse of the Allegheny Plateau. Residents often observe how the light catches the moisture rising from the ground at dusk, turning the low-lying fields into a soft, monochromatic gray. Beyond the immediate foreground, the distant silhouette of the Allegheny Mountains provides a jagged, permanent horizon that anchors the entire perspective. Those seeking a quiet reprieve from the daily bustle frequently visit Ballfield No. to observe the seasonal changes in the vegetation and the local wildlife.
South Fayette emerged from a history deeply rooted in the extraction of coal and the steady, industrial labor that fueled the regional growth of the nineteenth and twentieth centuries. The local economy has since transitioned away from these heavy subterranean origins, shifting toward a diverse mix of modern professional services and residential development. While the physical evidence of the old mines has faded into the landscape, the industrious spirit of the past remains a quiet undercurrent in the way the local commerce functions today. Families often travel to Lynch Ponds when they desire a moment of stillness, reflecting on how the land has repurposed itself over the decades. This shift in industry has fostered a steady, methodical pace of life where the primary focus is the maintenance of a stable, functional environment for its inhabitants.
Cultural life in South Fayette thrives on a shared sense of community that values accessible public spaces and a grounded, pragmatic outlook. The area maintains a connection to the broader region through the nearby Duquesne Incline, which serves as a landmark link for those traveling toward the nearby urban centers. Local events often center on the school district, which acts as a primary hub for social cohesion and the celebration of youth achievement. While the locality remains modest in its public profile, it maintains a distinct identity that resists the homogenization found in more transient regions. The quiet dignity of the streets and the deliberate preservation of its character ensure that South Fayette retains a sense of purpose for those who choose to build their lives here.

Search Maps opens a second, independent map. It searches OpenStreetMap for any US town, county or landmark by name; offers USGS topographic maps and USGS aerial imagery as base layers; overlays a labelled U.S. National Grid (USNG) so the map can be read like a printed topographic quad; measures distance and grid, true and magnetic bearings between any two points; and takes a single GPS fix reporting your position as a USNG grid reference and as latitude and longitude. Map tiles require cell coverage, but a GPS position does not, so the coordinates remain correct even where the map cannot load.
Location data is drawn from the USGS Geographic Names Information System (GNIS) and cross-verified against 2020 US Census records by coordinate proximity. Population figures are sourced from the 2020 US Census.
