Where two line features cross but are not physically connected (or related), I would like to symbolize the crossing using a line jump symbol. Visio is capable is using such symbology:
In 2008, Esri said "we might get this on the list of enhancements for future releases." I've seen no update to indicate that the enhancement was ever made.
Are line jumps possible in ArcMap today, either natively or via a workaround? If you've employed a workaround, what is it?
EDIT 3/7/2016: I would like to do this without modifying the underlying geometry, if possible.
