we noticed something a little odd. Many of the signs for intersecting roads were single letters, (e.g. A, H, W)
Jim speculated that since the first interstate project was in
St. Charles, MO, perhaps back then they decided to name the cross streets
alphabetically. When they ran out of
letters they doubled up, but soon they ran out of even the double letters. We don't know -- this was just idle
conversation.
