   The "Motorway Junction" tag at
http://wiki.openstreetmap.org/wiki/Motorway_junction has recently had 
the exit_to tag added.  Old interstate tagging advice at

sign destinations in the "name" tag.   However this is not exactly 
correct, especially for the case of highways with named exits.

    The latest JOSM-Tested now includes the exit_to tag as part of the 
preset highway junction dialog, so people who use JOSM will be guided to 
the new standards.

    For standardization purposes, all existing highway junctions should 
be updated to the new convention.   (Junctions which contain name= but 
not exit_to= should be changed).

    Question: Can this be a mass edit for the whole US?  The results 
would all be correct except for the case of 'named exits' which properly 
used the name only, but have no exit_to tag.    In any case, I wouldn't 
propose making a mass edit for 1-2 months as this settles in everyone's
