Council Bluffs/Omaha Highway Chronology

The history of highways in Council Bluffs is intertwined with the history of highways in downtown Omaha. These maps include highways in Omaha west to about 50th Street. Special thanks to Jesse Whidden and Neil Bratney for their help with early highways on the Omaha side.

NOTE: IA 2 and 7 may have continued along Broadway into Nebraska along with IA 6
End 8 and 104: Main at Broadway

November 3, 1924: IA 12 truncated at Missouri Valley; IA 104 truncated to IA 8
April 5, 1926: IA 104 decommissioned
October 16, 1926: US 30 replaces IA 6; US 32 replaces IA 2 and part of NE 16; US 75 replaces IA 12 north of Council Bluffs, IA 7 to bridge, and NE 5 south of Douglas St; US 34 replaces IA 8

NOTE: The above map shows the ends of US 32, US 34, and US 38.

May 27, 1931: IA 241 designated along former IA 86 route, then east to US 34
June 24, 1931: One month after 241 is designated, IA 192 replaces it
November 1931: US 275 commissioned; overlaps with 34 north of Glenwood
December 1931: US 6 replaces US 32 and 38; US 30 becomes US 30S
1932: IA 192 truncated to west of US 34/275; later to Lake Manawa
1932 (no later than June): US 73 extended northward to South Sioux City along NE 5 and US 77

NOTE: Route descriptions in Highway Commission minutes on February 5, 1936, show routes using Pearl instead of Main, half a block west. It is unknown when this began and maps are unclear on how long it lasted.
US 6, W-E: Saddle Creek Rd, Dodge St, 30th St, Douglas St, Douglas St bridge, Broadway, Oak St, Pierce St, McPherson Ave
US 75, N-S: North Broadway, Broadway, Douglas St bridge, Douglas St, 24th St

1934 or 1935: US 75 moves to 13th St south of Douglas
1935: Discussion about the Iowa-Nebraska border involves potential relinquishment of Carter Lake (which would, inevitably, be annexed by Omaha). Such action never happens. Border is mostly settled along channel of Missouri River as of mid-20th century, except Carter Lake, in Supreme Court case Nebraska v. Iowa, 406 US 117 (1972).
