text: Hi,
  In the overspill from the ESRI Community aerial imagery at zoomlevel 21 for Connecticut, it is clear to see (but not in Bing z20)...
  A gate, and what appear to be three bollards, and further sets of bollards off-road, plus surface markings.
  Not enough to prevent one set of tyre tracks visible on the grass...
  I am adding some of these barrier elements to the road.
  A better-qualified mapper is more than welcome to correct and improve my armchair mapping here as I knoweth not what I do.
  thanks
