If you look at a map of the Quad Cities area, you'll see that US 67
runs east and west (thanks to the westward turn the Mississippi River makes
at Le Claire) while I-74/US 6 runs north and
south as the two routes intersect in Bettendorf. Yet US 67 is signed north-south
while I-74 and US 6 are signed east-west.
US 67 follows the Great River Road for almost its entire route, up
to the foot of the Centennial Bridge in Davenport. (It actually shares
about half a mile with US 61 in downtown Davenport
before separating, as US 61 picks up the Great River Road from that point
