BridgeLocator
Locate bridges near you in the United States using your location obtained from GPS or Wifi (Database contains thousands of bridges directly from the NBI – National Bridge Inventory). Get driving directions to the bridge from your current location and see a satellite view of it. Save bridges to a favorites list (accessed by pressing the Settings key) so you can come back to the bridge later. If available, see detailed inspection data for the bridge (currently only for bridges in North Carolina).
