text: Intersection at Wyong Rd / Enterprise Drive has been upgraded from a roundabout to traffic lights.
  (see http://www.rms.nsw.gov.au/projects/central-coast/wyong-road/enterprise-drive.html )
  
  This has been fixed in changeset http://www.openstreetmap.org/changeset/43112480
  
  The only thing left to do might be to add divided roads for Enterprise Drive / Chittaway Road and add turning lanes.
