History
|
Designated: November 2, 1931, along parts of US 34 (from Council Bluffs to Glenwood) and IA 4 (I) (from Glenwood to the Missouri line).
US 34 and 275 shared about 18 miles of the route until US 34 was re-routed away from the Omaha/Council Bluffs area in 1935.
Paving history: The entire road was paved at the time of designation.
Major alignment changes:
1939: Extended from Council Bluffs into Omaha on the Ak-Sar-Ben Bridge, sharing the bridge with US 6, US 30A, US 75, and IA 92.
1941: Routed away from the Ak-Sar-Ben Bridge and West Broadway in Council Bluffs onto the South Omaha Bridge and the former IA 367.
The old segment into downtown Council Bluffs became IA 375.
July 1, 2003: Re-routed onto I-29 and US 34 between the split with IA 92 (I-29 exit #47)
and Glenwood, extending the multiplex with US 34 and creating one with I-29. The standalone
segment between Council Bluffs and Glenwood became County Road L35.
September 2006: Two-lane bypass to the east of Sidney opens (part of which is multiplexed with IA 2)
For street alignment changes in Council Bluffs, see Jeff Morrison's Council Bluffs/Omaha Highway Chronology page.
Upgrades:
May 24, 1974: Expressway segment near Glenwood (with US 34) opens. (The segment opened to two lanes on January 26.)

Notes

|
Nebraska and Iowa plan to replace the South Omaha Veterans Memorial Bridge, which dates back from 1935, with a new four-lane bridge that is located about one-half mile north of the current bridge. Completion is scheduled for 2010. More information on the project can be found here.
