Iowa 100 (I)

Designated: July 1, 1920 Decommissioned: June 23, 1958
Original western terminus: Griswold; it was extended to US 275 in Council Bluffs on December 22, 1936.
Original eastern terminus: US 71 at Lyman
Paving history: There were no paved segments at designation.

1952: Paved from Griswold to US 71

1956: Paved from Council Bluffs to US 59

1957: Last segment, from US 59 to Griswold, paved

Major alignment changes: IA 100 was originally a north-south spur between IA 2/24 (now US 6) southward into Griswold; it became an east-west road by 1923.
Replaced by: County road, which later became part of IA 48 (north-south alignment in 1923); a relocated IA 92 (at decommissioning)
For street alignments in Council Bluffs, see Jeff Morrison's Council Bluffs/Omaha Highway Chronology page.

Iowa 100 (II)

Designated: June 23, 1958 Decommissioned: July 1958
Original western terminus: US 6 north of Lewis
Original eastern terminus: US 71 in central Cass County
Paving history: The entire road was paved at the time of designation.
Replaced by: IA 414.
Jeff Morrison discovered what may be the shortest-lived state highway in Iowa history through newspaper research, as it does not appear on any state highway map. When IA 92 replaced the original IA 100 on June 23, 1958, the five-mile segment of old IA 92 that was not co-signed with US 6 became IA 100. However, motorists were confused that the new IA 100 was so close to the old road, so in late July, the Highway Commission renumbered the road as IA 414.

	Iowa 100
	Length: 8.3 miles/13.4 kilometers Western terminus: Edgewood Road in Cedar Rapids Eastern terminus: US 151/IA 13 in Marion Terminus photos The entire road is a four-lane divided highway. Counties: Linn Cities along route: Cedar Rapids, Marion NHS: Entire route
	History
	Designated: August 14, 1984, replacing part of IA 150 Paving history: The entire road was paved at the time of designation. Major alignment changes: July 3, 1985: Extended westward from its previous west end at I-380 to Edgewood Road November 25, 1996: Extended eastward from First Avenue (Business US 151) to US 151/IA 13 east of Marion along the Marion Bypass. For maps of IA 100's alignments, see the Highways of Cedar Rapids page.
	Notes
	A western extension of IA 100, which has been proposed since the 1970s, will eventually curve southward across the Cedar River and connect with US 30 west of Cedar Rapids. This new freeway segment would complete a four-lane loop around Cedar Rapids following IA 100, US 151/IA 13, and US 30, but controversy has come with these plans. There was some early concern that an orchard and housing subdivision would be razed by the new highway, and in mid-October 2000 the Linn County Conservation Board recommended that the Iowa DOT find another route to avoid any negative impacts on the Rock Island Forest Preserve (near where IA 100 would cross the Cedar River). Those concerns were echoed when Byssus skipper butterflies — which are on Iowa's threatened species list — were found to be living in the area in August 2001. Despite pleas from environmentalists to abandon the project altogether, the Cedar Rapids City Council voted on August 29, 2001, to move on with the plans. The IA 100 extension was scheduled for completion in 2005, but funding problems and continued opposition from environmentalists have postponed completion. According to the 2013-2017 state transportation plan: a new Cedar River bridge is programmed for completion in 2014, paving of the segment between County Road W36 (old IA 94) and Edgewood Road is programmed for fiscal 2016, and grading of the segment between US 30 and W36 is also programmed for 2016. This video has aerial views of the planned IA 100 extension.

Iowa 101

Designated: July 1, 1920 Decommissioned: August 14, 1984

Original southern terminus: IA 40 (later US 218) at Vinton
Paving history: At the time of designation, the only paved segment was from Vinton to the Cedar River crossing. The rest of IA 101 was upgraded from bituminous to paved in 1955. (The north-south segment north of the river was moved onto its present alignment in 1942 or 1943.)
Replaced by: IA 150.

IA 101 was the highest number in the original 1920 numbering system, but IA 102 through 107 were designated by the end of the year, as all of those highways appeared on the 1921 map.

Terminus photos

History

Designated: 1980, originally running between IA 163 in Pella to the US 63/IA 146 junction in New Sharon
Paving history: The entire road was paved at the time of designation.
Major alignment changes:

1996: West end moved to the easternmost interchange (exit #44) of the IA 163 freeway bypass of Pella

May 2003: Segment between the west end in Pella and the western terminus decommissioned; it is now signed as County Road G5T, its pre-1980 designation. All IA 102 signs, including those in New Sharon, were taken down by May 9 but the road remains under state control within the city limits of New Sharon.

Iowa 103

Designated: 1920 Decommissioned: July 1, 2003
Original western terminus: IA 40 (I), later US 161 and most recently US 218, in northwestern Lee County
Original eastern terminus: US 61 in Fort Madison
Paving history: Unpaved at designation, the segment from West Point to Fort Madison was paved in 1938. The segment west of West Point was gravel until 1949, and had a bituminous surface until it was paved in 1988.
Replaced by: County Road J40. The DOT had originally planned to take IA 16 east of US 218 instead of IA 103 as part of the legislation passed in 2003, but after reviewing the poor condition of the road, they decided to keep IA 16 in order to resurface it later and give Lee County IA 103 instead.

Original northern terminus: US 34 in eastern Clarke County
Original southern terminus: Woodburn
Paving history: There were no paved segments at designation, and the road was bituminous at decommissioning but has since been paved.

Iowa 105

Designated: 1920 Decommissioned: December 31, 1992
Original western terminus: IA 15, later US 69, in Lake Mills
Original eastern terminus: IA 40, later US 218, in St. Ansgar
Paving history: There were no paved segments at designation.

1952: Paved from Lake Mills to Northwood

1960: Last segment, from Northwood to St. Ansgar, paved
Replaced by: County Road 105 (thanks to Steve Riner for pointing this out in 1998), which is the first county road in Iowa that does not follow the traditional alphanumeric numbering system. It is signed just like any other county road. The segment in Winnebago County was unsigned IA 971 until 2001 (it remained in Lake Mills until July 1, 2003), while the segments through Northwood and St. Ansgar were designated (though not signed) as IA 972 and IA 973, respectively, until July 1, 2003.
Incidentally, IA 105 never did connect with MN 105, which runs from Austin to the state line and continues as County Road S70 in Iowa southward to County Road 105.

The Cerro Gordo County Board of Supervisors approved the transfer on December 30, 2002; Chris Dobel reported that all signs along this stretch of IA 107 were taken down by June 4.
Original southern terminus: Thornton; it was extended westward and southward to Meservey on June 4, 1935, and southward to IA 10 (now 3) in western Franklin County via Alexander on June 7, 1939, superseding IA 297 (I) along the way.

The Iowa Transportation Commission approved the transfer of jurisdiction of the piece through Meservey at its meeting on July 13, 2010, and of the piece through Thornton on September 14, 2010. The city of Thornton was scheduled to take over its piece of IA 107 on June 30, 2011, according to the Cerro Gordo County Board of Supervisors' meeting notes from July 12, 2010.
