How to Use This Three Bridges, New Jersey Map

This interactive map shows the street layout and satellite imagery for Three Bridges, New Jersey. 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 New Jersey 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 Three Bridges.

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.

About Three Bridges, New Jersey

Three Bridges emerges from the landscape as a quiet confluence of pastoral stillness and the persistent, low-frequency hum of the South Branch Raritan River. It lies 3.7 miles northwest of Montgomery, NJ (from Montgomery, NJ: bearing 320°T), and is situated 6.9 miles east-southeast of Hunterdon. The river carves a deliberate path through the earth, its waters tracing the contours of the Readington Township Wooded Lot that frames the eastern edge of the locality. Beyond the immediate banks, the terrain rises into subtle, firm elevations that suggest the distant silhouette of Middlebrook Heights on the horizon. The air here holds a particular quality of clarity, especially during the long, amber-hued afternoons when the light catches the silt in the riverbed and turns the surrounding fields into a vast, monochromatic study of gold and slate.

Historical threads of Three Bridges remain anchored in the agricultural legacies of the nineteenth century, though the modern rhythm of the place reflects a shift toward a quiet, residential composure. The local economy, once tethered to the mills and the produce of the surrounding earth, now functions as a transition point for those who favor the proximity of the countryside over the density of larger, more frantic hubs. Life in Three Bridges moves with an inward-looking gravity, characterized by the maintenance of properties and the seasonal changes in the vegetation that define the view toward the distant, shimmering expanse of Round Valley Reservoir. Even as the modern world encroaches, the land retains a sense of seclusion, maintaining a steady, grounded existence that owes little to the outside world beyond its own borders.

About This Three Bridges Map Page

This page provides an embedded street and satellite map of Three Bridges, New Jersey. Coordinates: 40.519826, -74.79933. Live weather conditions are sourced directly from the National Weather Service. Real-time local and world news feeds keep the page current.

Detailed location data for Three Bridges includes the ZIP code (08887), telephone area code (908), county seat of Hunterdon County (Flemington), and school district assignment (Hunterdon Central Regional School District).

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.
