After looking through several road-related newsgroups, this is the
longest state highway I know all of the lower 48. Purists don't agree
because of the 3E/3W split (shown in the map above in purple and
orange), but if you
follow the 3E route (one, because it's longer; and two, because this is
the
direction OK-3 took before the E/W split back in the 70s) this highway
runs
for 616 miles, longer than even any state highway in Texas!
