IA: Interstate 880 (Iowa)

[the_spui_ninja]

The split puts I-80 on the inner "Express" lanes and I-29 with "Local" lanes (also signed as I-80). It can be argued that if one travels I-29 through, they were never "on" I-80, and vice versa.

I will argue such. Methinks, track them separately and give travelers the option to clinch one and not the other should they so choose.

That's what it looked like the last time I was in Omaha, so that makes sense.

The week between Christmas and New Year's at lightning speed, maybe. Next March/April more likely, IMO. I'm not touching anything until there's confirmation in the field. (Unfortunately, it's not going to be me doing that first-hand. I am very glad I took some necessary pictures in summer.)

I'll be sure to go through Omaha/N. Omaha the next time I have to go to Kansas City (probably in January) and see if anything is up yet.

Hmm - need help?  I could be due for a field check over the next month.

Doesn't look like exit numbers will change: https://iowadot.gov/maps/MapParts/Section%206.pdf

This deal is getting worse all the time!

In seriousness, it could be related to either 1) the 2019-20 map was released about Memorial Day weekend, and that part hasn't been changed yet or 2) they are going to keep the exit numbers identical for reasons of keeping as much coherence with the previous setup as possible (and, say, GPS's like mine that can't update anymore).

For Council Bluffs, froggie and yakra gave diametrically opposite answers at the end of the previous page, so...that's interesting.

The I-29/I-80 thing is about separating the newly opened dual-divided freeway, which was built over the same place as the existing four-lane, so I wouldn't see it on the same level.

Speaking of, though: Should I handle that in some manner? Right now I-29 and I-80 have a concurrency. The split puts I-80 on the inner "Express" lanes and I-29 with "Local" lanes (also signed as I-80). It can be argued that if one travels I-29 through, they were never "on" I-80, and vice versa.

I can do nothing, mark the two exits in the middle as "closed" on I-80 (since, if you are traveling the Express, you can't take them), or twiddle some coordinates to break the concurrency.

The concurrency break of I-29 and I-80 is going in tonight, but I'm not sure if there should be an updates entry.

My initial response was going to simply be "Meh!" Although...

I grepped the following travelers from concurrencies.log:

There may be a comparable or even greater number with both already marked.

Any of these people may want to review their 29/80 travels, and mark both routes. Or just one. Or unmark one. Etc.

FWIW, comparing historicaerials in 2016 & 2012 suggests the former EB 29/80 lanes correspond to the new EB I-29/local lanes, and the former WB lanes correspond to the new EB I-80/express lanes.

I'll leave it to others to decide whether to add an updates entry, or how to word one.

FWIW, I plan to not change anything in my list file. I've previously clinched I-29 and I-80 in Iowa from border-to-border. If one or the other or both have shifted alignments a little in Council Bluffs due to their newly-separated adjacent roadways, I would not consider that a de-clinching event.

Ditto I-680 => I-880 when that happens, except I may need to adjust for the new 680 and 880 endpoints.

[Duke87]

I would add an update entry for this and have it look something like:

IA I-29   Removed from concurrency with I-80 onto new parallel roadways.
IA I-80   Removed from concurrency with I-29 onto new parallel roadways.

And this then notifies anyone who has been through on either to take a look and see what they want to do.


I am also in the camp that I will not count the segment of either route declinched - my reasoning is I already count other cases where one route straddles another the same as if they are concurrent. So from my perspective nothing has meaningfully changed here.

[yakra]

I won't de-clinch.
I've traveled old westbound AKA new I-80 / US6,
and traveled old eastbound AKA new I-29.

Given this map, the numbers might not change at all.

I asked the Iowa DOT on Facebook about the exit numbering situation when they made the announcement, and they said the exit numbers were changing.

I'm finally getting around to making site updates today even though signs apparently haven't changed in the field yet.

Highway63 doesn't use Facebook.

Neither do I, but I was able to see a linked photo with an I-880 marker.

[Jim]

I-680 is truncated and I-880 is added in tonight's (in progress at the moment) update using files sent by Jeff via email.
