text: AFAIK, this roadway has no name, unofficial or otherwise. This section that runs along the Waterway is meant for use by the Town Center Trolleys and the park ranger golf carts. The public can and does use it for foot and bike traffic but it seems to have been designed explicitly for the trolleys as there are barriers preventing vehicle entry on both ends of the path.
  Here's a link showing the trolley route:

  In this case it might make more sense to change the feature to something that wouldn't route like a road or maybe tag it as "motor_vehicle=no".
