Iowa map goofs redux
This is a list of goofs I have seen on the 2004 and 2005 state
maps. This list includs mis-marking of highways, lack of mileage
between certain points, "leftover" mileage not deleted
after the decommissioning of state routes, mileage that didn't
add up between stars (and, in some cases, mileage that was counted
in two different directions), and mileage that didn't break up
on each side of a town. I also point out places where a smaller-text
number could be added in areas, or where a red number (between
starred points) could be added. (I figure that omissions in areas
where numbers might not fit aren't technically goofs, but noted
them anyway.) This page lists most of what I sent to the DOT in
2004. The list is separated into categories, with text for things
that WERE changed for the 2005 map (plain text), things that were
NOT changed (bold), things I didn't have on the
original list (bold italic), and additional comments
in italics. ((Year) indicates first map year this
was an error, if known.)
A lot of these are tiny things. But I like the Iowa map, I
think it's an excellent product, and I'm a perfectionist. And
there are some moderately noticeable mistakes and "highway
residue" from old routes on the map.
Oldest non-mileage errors: Ogden interchange (built 1964/marked
as partial 1981); US 34/71 "secret" interchange (1970s);
US 30 expressway/freeway in Ames (1991)
Oldest mileage errors: IA 3 in western Cherokee County (1970s-80s);
not combined on US 63 after IA 57 was truncated (1981); not combined
on IA 2 after IA 25 was truncated (1983); not removed on IA 3
after IA 134 was decommissioned (1990)
Omaha-Council Bluffs (miscellaneous); black mileage
in Vinton (delete circled)
Page put online 3/29/05; last updated 4/27/05
- MISCELLANEOUS (3 fixed, 1 sort of fixed)
- Omaha area:
- All of NE 38 in Omaha was decommissioned Jan. 1, 2003,
so it should be removed. Signs have been taken down, including
on I-480. - Not fixed (2004)
- Remove mileage on L35 (Old US 275), to the right of I-29
exit 47 marker (5) (2004)
- Remove mileage at Crescent (2) (2004)
- I-29 between exits 47 and 42 - change black 6 to 5(?)
(47-42) - there's a red 6 there also, which I think is
for I-80 to IA 370. The five miles would be IA 92 to IA 370.
- Add mileage on US 275/IA 92 west of I-29 and on US
6 (if space)
- Mileage on I-80: Distance between west juction
I-29 and IA 192 is 3 miles; distance between IA 192 and east
junction I-29 is 1 mile, so "2" should be a 3 or maybe
4 (because the scale is so small)
- Add mileage on IA 370 in Iowa (3) (just below area shown
- US 218 between Vinton and US 30 - remove black mileage
(10, 3) - Now US 218 is black, but the numbers are still
- IA 150 between Vinton and I-380 - remove black mileage
(12, 1); it might look better if red star was moved to where
"1" is - Now IA 150 is black, but the numbers
are still there (2004)
- Old IA 181 is S45, not S44 - fixed
Ogden: US 30/US 169 is a full four-ramp, not partial, interchange
- Error since interchange was first actually placed
on the map (1981)
- Oskaloosa: Part of US 63 south of IA 92 is black when it
should be red - Rendered moot by changing 63's color
Fort Madison: A small piece of Old IA 103 is marked inside city
limits (right circle). If this has been turned over to the city,
remove and combine mileage (4, 2). (2004)
- US 65: Not multilane divided in the Colo area (between US
30 and County Road E41) - fixed
US 30 between US 69 and I-35 along the south side of Ames should
be marked as freeway - Wrong since intersection
was removed in 1991; section at Dayton Ave. still only marked
as "multilane divided" though this is less visible
since addition of interchange square. Inset is correct.
- US 30 in Cedar Rapids: 16th Avenue and 80th Street
interchanges should both be partial interchanges, both on the
main map and the inset, just like Marshalltown - pointed
out by Jason Hancock; interchanges built in 1980s but not marked
- Ida County: Swap the positions of the red star and the
"1" west of Ida Grove to clarify that the star is the
west US 59/IA 175 junction and not the town (as measured in three
of the four directions). To fix the fourth, the red "22"
on IA 175 to the southwest should be "21". - The
"1" between US 59 and Ida Grove is still being used
in both directions on 175. US 59 uses the west intersection.
- IA 146: Is expressway (multilane divided) between Grinnell
and I-80. - It's possible that the lanes aren't far enough
apart to be "divided" on the map, though it is four
lanes with a small median. County map shows this.
- US 75 around Sioux City: Main map missing interchanges
at 25th Street (north of US 20) and Lakeport St/Road (with US
- Clinton: Is 67's current bypass of downtown Camanche
marked on main map? - It doesn't look like it
- Underwood: Connect paved G30 at I-80 interchange west
to County Road G8L (Old IA 191)
- Brooklyn: Draw V18 between Brooklyn and US 6
Old IA 955/963 south of Dubuque: The red line near the expressway
is still there and not changed to gray. - And now it's
- I-80 at US 65: It looks like the interchange square is
slightly left of where the roads actually intersect, looking
like the county road meets I-80 instead. The square should be
almost directly under the 142 exit marker. (1994)
- US 34 at Red Oak: When I drove this route in June 2003 the
road was not multilane divided, but rather a two-lane with extended
third lane for eastbound traffic. - Removed
- IA 44: "8" between Panora and Guthrie Center
should be in red
- US 34 at US 71: This intersection is a full four-ramp
interchange. US 34 is multilane divided for a short distance
in this area, from about half a mile west (across the Nodaway
River) to just over a mile east. The eastern point of the four-lane
is approximately where County Road H34, north of 34, has a pair
of curves. - Probably around since realignment in the 1970s.
Also, 34-59 isn't at-grade, but there's no way an interchange
square will fit there. I can see why these are not marked.
- Ames: IA 930 black line should not be east of Boone County
line, gray instead - Now the whole thing is gray, but I don't
think the section in Boone County was turned over. (1980/2005)
- IA 92: "8" southeast of Harvey should be moved
to the west, between IA 5 and Harvey - Prior to 1997,
that "8" wasn't even there, but now that it's been
added, it needs moved.
- W64 can now be marked along Old US 218/Old IA 923 in Washington
County instead of arrowed notations near the ends - Then
again, maybe it doesn't fit. Not necessarily a goof. (2004)
- COMBINE MILEAGE (3 fixed)
IA 2 south and west of IA 25 (2, 13) - Now entering its
22nd year, but not the oldest (1983)
US 63 between Denver and downtown Waterloo (9, 3) - Oldest
leftover on the map. Still there after IA 57 was truncated in
1980. Airline Highway, old 57, is the divider.(1981)
- IA 148 between IA 92 and Corning (20, 4) - Fixed, and
now there's a star at the 92/148 junction.
- IA 17 between Eagle Grove and US 20 (13, 2) (2004)
- IA 17 between Madrid and IA 141 (2, 7) (2004)
- IA 127 west of Magnolia (4, 1) - Fixed!
- IA 92 between Oskaloosa and IA 21 (5, 11) - Fixed, but
a "1" needs to be added between US 63 and IA 23
to make the red starred mileage add up (this is where that extra
- US 34 between IA 48 and US 71 (8,6) - remnant
of IA 115 (2004); mileage has fluctuated in past
- IA 25 between Guthrie Center and I-80, red starred mileage
(11, 4) - Technically, perhaps, not a goof, but why split
at a county road? (2004)
- I-80 between IA 25 and US 169, red starred mileage (14,
10) - Still starred at old 6. Technically not a goof.
- US 30 between Glidden and Scranton (6, 4) - Still
a goof, unless Ralston is considered to be "on" 30.
- DELETE MILEAGE (4 fixed)
- West of Beeds Lake symbol (8) - Remainder
from IA 134 (1991)
- On US 67 between IA 64 and Clinton (9,7) - originally
split, I think, at a town that hasn't been on the map for 30
- South of Plano (5); the "14" west of Centerville
is the total Centerville-Promise City mileage (2004)
- Southwest of State Center (7); the "15" southeast
of State Center is the total IA 330-US 65 mileage. Or add an
"8" between State Center and IA 330. (1995)
- Southeast of Spirit Lake (1) (2000)
- On Old IA 415, to the right of the IA 17 shield (9)
- East of Garwin (6)
- West of West Point (6)
- Along Old IA 49 (8, 3, 10)
- Downtown Waterloo: Has two red stars (see arrows on
map above) - (or is this intentional?)
- ADD (THAT IS, PLACE NEW) MILEAGE (2 done)
- US 20 between US 65 and IA 14, both starred and between interchanges
(this could result in splitting up starred mileage on IA 14,
and it did). Currently, 20 has no starred mileage between
US 65 and the east I-380 split. - Done and done.
Conflicting mileage on IA 122
- Mason City area: Downtown still has a red star. I would
delete it, change the red "9" on US 65 north of Mason
City to black and add a red "12", add a black "3"
between IA 122 and US 18, and pick one number to be black on
IA 122. (That 9 and 8 are for the same stretch of road.) -
The star itself isn't a goof, but the 9 and 8 on the same road
- Sioux City: On US 20/US 75 southern and eastern freeways,
and perhaps Business US 75 too.
- Cedar Rapids: US 30 between US 151 and I-380 (?)
- US 218: Around the Mount Pleasant bypass
- Des Moines: IA 5 and US 65 between I-35 and IA 163
- IA 163: 3 or 4 miles between the two Monroe interchanges
- It's 4
- US 61: 2 or 3 between IA 64 and south Maquoketa interchange
- US 61: Black mileage between Fort Madison and Burlington,
split at IA 16 (8-8) - Probably removed because at one
point that part of 16 was going to be killed in 2003 (2004)
- US 61: Between IA 22 and north junction of IA 92 -
A "4" was added between IA 22 and IA 38. (1986)
- Clinton: Small black numbers between south junction US
30/67 and north junction (2), and between that intersection and
US 67/IA 136 (2)
- Dickinson County: Along IA 86 between IA 9 and US 71;
US 71 between IA 86 and Okoboji (split at Arnolds Park) -
It's quite possible that the numbers simply don't fit.
- US 65 between IA 57 and US 20: Change 6 and 5 to black,
remove red star at Iowa Falls, add red "11" -
Technically not a goof, but it might help. (2004)
- I-380: Red "22" between US 20 and IA 150; red
"27" between IA 150 and US 30; black "3"
between exits 65 and 62 - I-380 still has no starred mileage.
Technically not a goof
- US 151: Could add a red "23" between US 6 and
Cedar Rapids - operative word being "could".
- IA 12: Could add a red "13" between Hawarden
and Akron and red "28" between Akron and Sioux City
- Along IA 934 in Waterloo (in small type) - but
everywhere else in Waterloo does have mileage, and the interchanges
are now marked; not really a goof
- Along IA 100 in Cedar Rapids (in small type, if possible)
- IA 122: Small black "4" between US 65 and the
- US 63: Black "17" between Bloomfield and Ottumwa
- CHANGE MILEAGE (3 done)
- Summary of changes needed for Oskaloosa area/Mahaska County
(also noted elsewhere): Add black "1" in town between
US 63 and IA 23. Change red "22" by 92 shield west
of Beacon to "23" (2+8+13). Change red "28"
southeast of Eddyville to "30". Change red "29"
by Cedar to "32". Change red "24" on IA 137
- Parkersburg: As currently starred on IA 57, to the
west, 8+6+4+5=23=red star is at WEST junction of 57/14, but to
the east, 8+10=18=red star is at EAST junction. On IA 14 (2005
map), 7+2=9=red star is at WEST junction. - Now that 14's
mileage has been changed, its numbers further the confusion.
I'd keep the star at the EAST junction since that's what it looks
-- Change red "23" on IA 57 by Ackley
-- Add red "14" on IA 14 south of Allison, change red
"9" south of Parkersburg to 7, remove black 7
-- OR, if star considered to be at WEST junction, change red
"18" near New Hartford to "20" and make "12"
south of Allison red
IA 3 west of Cherokee
- IA 3: The mileage between IA 143 and US 59 should be 4-4-5
instead of 5-5-3. The "3" between Meriden and US 59
is actually a longer distance than the "5" between
Cleghorn and Meriden. - Still a goof, still not fixed.
Actually marked as 4-5-4 until 1977, and then 4-5-3 until 1983.
The distance between 143 and L40 is exactly 4 miles, though to
downtown Cleghorn is a half-mile more. Regardless, the distance
between Meriden and US 59 is the longest of the three, and 4-4-5
would be a more accurate representation.
- De Witt area: Black "6" between Grand Mound
and US 61 should be "4". Red "32" by Calamus
should be "30". "4" near Welton should be
distance between Welton and US 30.
- Marshalltown: Make "5" on IA 14 north of town
an "8" (since the city-center marking isn't on 14 itself)
or, alternately, add small black "3" between downtown
and US 30 - The 8 miles between IA 330 and US 30 is still
marked as "5" (1991) though the red "24"
by Conrad is right.
- IA 141: Change "6" by Sloan to "7"
or add "1" between I-29 and Sloan. I assume the
case of 6+9=16 between I-29 and Smithland has to do with the
removal of US 75 through Sloan.
- IA 24: There are currently two stars at New Hampton, about
one mile apart. Remove the star in the town (keep the one at
the interchange) and change the red "26" northeast
of Lawler to a "27" (with a black "1" added
between the interchange and New Hampton, if possible).
- I-235: "14" west of state capitol marker
should be distance between west end and US 69
- IA 5: Change "5" near Pleasantville to distance
between IA 316 and IA 92 (7?) (2005)
- IA 415: Change "8" along route to current mileage
between IA 141 and IA 160 - well, I guess adding the mileage
between IA 141 and Polk City works too.
- IA 163: Change "7" at Polk/Jasper county line to
the distance between US 65 and Prairie City - and all the
mileage adds up, too.
- US 275: Change "1" near state line at Hamburg
to "2" (2004)
- US 59: Change "9" south of IA 2 to "11"
- distance between IA 2 and state line (2004)
- IA 163: Between Monroe and Oskaloosa, 6+7+3+2+14+2 (the last
2 was, in 2004, unmarked on IA 92 between IA 163 and US 63 in
downtown Oskaloosa) does not equal the red 30. - Red star
was moved to 163-92 interchange, so 30 is now right. Mileage
on 63 (and 146!) changed to match, but others are off. See above.
- I-80 in Davenport: Change red "12" by I-80/US
61 to "6"; stray red star on I-80 near County Road
Z30 doesn't make any sense, so I suggest removing it, changing
the red "5" to black, and adding a red "11"
between US 61 and US 67. - The red "12" is a goof,
if the red star at 80/61 applies to I-80. The rest technically
isn't a goof, but still weird
- IA 175 between I-29 and Mapleton: Delete red star at Onawa,
change red "2" to black, change red "21"
southwest of Mapleton to "23" - Technically
not a goof since the numbers add up, but a remnant from US 75.
- US 30 between I-29 and Logan: Missouri Valley doesn't
seem like the place for a red star anymore. I would move the
red star to I-29, change red mileages on 30 near Missouri Valley
and Blair NE both to "13", and add/adjust red mileage
on I-29 accordingly (IA 175-US 30 becomes 37, US 30-I-680 becomes
a red 3 or 4 instead of the black 3). - Technically not a
goof. Might be more trouble than it's worth.
- SPLIT MILEAGE (2 done)
- IA 141: Split "6" north and south of new IA 415
interchange (into 2 and 4) - done
- Along US 71/IA 175 through Lake View; "10" should
be split into 5 west of Lake View, 5 east of Lake View - done
- US 20 between IA 150 and IA 187; "12" should
be split at Winthrop interchange (6-6 or 7-5) - This was
split before IA 282 was decommissioned (2004), though the 7-5
may have been based on old 20
- US 75 between Hinton and US 20; split "10" as
necessary between Hinton and US 20
- IA 14 between Charles City and Greene; "18"
should be split at interchange with US 218 (2-16) - originally
a "7" between 218 and 147, which should have become
2-5 in 2001
- US 52 between Durango and US 61: Redo numbers between
Durango-Sageville-IA 32-US 61 - there are two numbers
here, 6 and 3, where there should be three, maybe 4-2-3 or 4-1-4
- IA 17: Black mileage between US 18 and IA 3, split at
Renwick (18 north, 7 south) - Downtown Renwick is off
17, which may be the reason, but it's close
- IA 2 between Clarinda and Bedford; split "17"
east and west of New Market
- US 6 between IA 224 and Grinnell; split "10"
at Oakland Acres
- US 59 between US 18 and IA 9; restore split at Allendorf
(17 becomes 2-15) (2004)
- US 63 between IA 92 and Eddyville; split "10" north
and south of IA 163 - Original problem fixed and fixed well,
but see Oskaloosa note above
- MARK NEW COUNTY ROADS (2 done) (technically not goofs)
Old IA 102 (G5T), Old IA 49 (various), Old IA 107 north
of Thornton (S25), Old IA 142 (S70, J18), Old IA 339
(L14), Old IA 415 northwest of Polk City (R2F, like
before 1980?), Old IA 99 (Co. 99, like Co. 105)
- INSETS (4 fixed, 7 with mitigating circumstances)
- Omaha/Council Bluffs: Remove NE 38 shield and adjust multilane
marking accordingly - Still there, and most of it is now
- O/CB: Street used by NE 64 is Cuming, not Cumming (one
- O/CB: G37 line is thicker than it should be
- O/CB: Add US 275 shield to I-29 at south end - done
- Des Moines: County road on east side is F70, not E70 -
at least, I'm pretty sure it's supposed to be. Polk County doesn't
put up blue pentagons.
- DM: Add more street names in some places, especially
Ankeny - suggested by Jason Hancock
- Cedar Rapids: Stony Point Road, not "Stoney" -
I was wrong on this. "Stoney" is correct.
- Cedar Rapids: 16th Avenue and 80th Street interchanges
on US 30 should both be partial interchanges, both on the main
map and the inset, just like Marshalltown - pointed
out by Jason Hancock
- Ames: County road at northeast corner is R63, not R36
- Burlington: Remove, or at least make black and smaller, multilane
mark east of partial interchange in West Burlington (I see that
this will become a full interchange when construction is complete).
- Davenport: For consistency, remove "Ill." suffix
on "To Galena" in the northeast corner.
- Iowa City: Remove multilane mark on Old IA 965 at I-80 (or
maybe not); add a "To Davenport" (or West Liberty)
on US 6 at right side of inset
- IC: Space for a "To Mount Vernon" on IA 1
at north side? - suggested by Jason Hancock
- Sioux City: Change thicker black line for Old IA 377 (just
east of airport, on Sioux City/Sergeant Bluff border) to regular
- SC: Move "To Fort Dodge" to edge of map
- SC: "Le Mars" two words at northeast corner
- SC: Remove, or change to black, short multilane marking north
of I-29 exit 148 - done
- Waterloo/Cedar Falls: "V14" north of Cedar Falls
is not in a box
- W/CF: add interchange number (66) at V49 (Old IA 297)
- W/CF: "Greenhill Road" (one word, not "Greenhills")
mark should be moved to the right onto the road that has an interchange
with US 218 - done
- W/CF: "Cedar Heights" is two words
- W/CF: If possible, move interchange square for Exit 72
south slightly to intersection of San Marnan Drive and I-380
- W/CF: Thicker line for IA 21 could be extended slightly north
to San Marnan Drive - unless it's not actually part of IA
21. I'm unclear on this.
- W/CF: Also, it would look better for continuity purposes
if the small piece of US 63 south of Dunkerton Road (C66)
was also marked as multilane - this change would need to
be done to the main map as well. While not precisely accurate
(the four lanes are not divided), it might look better than conveying
the idea that 63 suddenly narrows to two lanes for that short
