but why stop
multicrossing is fun
i can remember an unnumbered unimproved ndsd state line 
road wandering back & forth for many miles over the prairie
crossing the border perhaps dozens of times in all
tho shown as a straight borderline road on most maps
for serious highways tho i would nominate state routes 120
wiggling along the ctny state line from ctw 
right across ashers favorite interstate 684 nip too
& continuing to downtown greenwich & rye off frame to the south

7&s=50&size=l&symshow=n
you can see a half dozen crossings or more on this swatch 
alone
without counting those that you cant discern here
nor those that you can see on the following swatches
i used to live nearby & drove & marvelled over this route regularly
& now you have made me curious enough to want to look for the 
official town of greenwich map depiction of it next time i am in the 
neighborhood
but i am pretty sure we are already in the neighborhood of at 
least the low teens
