text: I'm not sure about woodglen drive, but zooming in on the intersection it's pretty clear that there's no left turn from Executive Blvd to 355/Rockville Pike.
  
  I removed the 1-way link from Executive to 355 as if it were blocked by the median (though it is not) which should tell autorouters to not make left turns on this intersection from Executive Blvd.  Please close this note if you think this is resolved now?
