History
|
Designated: December 1934 (approved November 20), along part of the former US 55 between Dubuque and Davenport, following the Mississippi River. This included a duplex of US 52 and 67 between Dubuque to Sabula.
Paving history: At the time of designation, the segment between IA 136 in Clinton and Davenport was paved.
1934: Paved from Almont (a town north of Clinton that no longer appears on the state highway map) to IA 136
1937: Paved from Bellevue northward to a point between St. Donatus and Bellevue
1941: Paved from the split with US 52 to Almont
1946: Paved from the Dubuque/Jackson county line to a point between St. Donatus and Bellevue
1947: Paved from the split with US 61 to the Dubuque/Jackson county line
1954: Paved from Bellevue to Green Island
1955: Last segment, between Green Island and the split with US 52, was paved
Major alignment changes:
July 12, 1940: Centennial Bridge across the Mississippi (between Davenport and
Rock Island, IL, opens); tolls were collected until May 2, 2003.
1960: Realigned on a new road closer to the Mississippi River between Riverdale and
Le Claire, with the old hilltop segment becoming IA 417.
1967: Route truncated north of Sabula, eliminating the duplex with
US 52.

Notes
|
|
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
westward.)
