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". The MUTCD ( 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 to be.
