    History
    Designated: February 15, 1935 (approved November 20, 1934), 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.
  • June 30, 1959: Realigned on a new road closer to the Mississippi River between Riverdale and Le Claire, with the old hilltop segment becoming IA 417 in 1960.
  • January 24, 1968: Route truncated north of Sabula, eliminating the duplex with US 52 and removing the highway from Dubuque County.
  • June 17, 1982: 3-mile bypass of Camanche opens
  • For alignment changes in Dubuque, Clinton, and Davenport/Bettendorf that are not listed here, please see their respective highway chronology pages.

    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 Business US 61 in downtown Davenport before separating, as Business US 61 picks up the Great River Road from that point westward.)
