Just a nitpick: For exit numbers that consist of both a number and a
letter, should we insert a space? For example "20A" vs. "20 A".
( http://mutcd.fhwa.dot.gov/htm/2009/part2/part2e.htm#section2E31 ) says
"Suffix letters shall be used for exit numbering at a multi-exit
interchange. The suffix letter shall also be included on the exit number
plaque and shall be separated from the exit number by a space having a
width of between 1/2 and 3/4 of the height of the suffix letter."
Obviously this would depend on how each state agency actually does their
signs. In the Likelike Hwy. example there appears to me to be a thin
space between the "20" and the "A". Maybe a thin space (U+2009) would
work? Though that might be making things more complicated than they need
