I've compiled from several sources when most Interstates were created or numbered: http://en.wikipedia.org/wiki/User:NE2/Interstate_history
That's really nicely done. Thanks, NE2.
That's a really good resource, thanks!
Nicely done
Interesting to note that Hawaii's interstates weren't part of the original plan, but since they got approved in 1960, they're about as good as part of the original plan.
I-335 MN was approved by BPR in 1964. I have documentation that it was officially requested from the state highway department in April, 1963.
I would like to learn what was the first interstate contract awarded in each state.
For Minnesota, I can narrow it down to one of three possibilities:
- I-35W through Richfield and Minneapolis (active planning for this predated the 1956 Highway Act)
- I-494 along the Bloomington Strip
- I-35 near Medford
FWIW, I was always told that in California it was actually I-8 between the 2 El Cajon Blvd exits, essentially rebuilding El Cajon Blvd into an interstate grade facility with the left exit CA 94 connector from the end of Alvarado Pkwy to ElCajon city.(I did once see a pic of this exits opening with a CA 67 to CA 94 on the BGS)
Well done!
Nice list! One thing: Shouldn't I-238 be between I-37 and I-39? It is listed as if it were an I-x80...

It is an x80 in all but name.

The south leg of I-540 in Arkansas (AR 22 to the OK Line)
appears to have possibly built first, but as
AR 540. I have conflicting info on this. Bugo and I constantly fuss over this ;)

NE2 posted this link and I 540 didn't get completed until the 1980s. According to the 1978 aeriel, AR 540 ended at US 71 while north of AR 22 (Rogers Ave) was already designated at I 540
I analyzed the 1957 additions, and they couldn't have all been added at that time (there's not enough mileage): http://en.wikipedia.org/wiki/User_talk:NE2/Interstate_history
That must be what http://www.ajfroggie.com/roads/yellowbook/additional-mileage.htm means by "the earmarking of mileage to provide circumferential or belt routes". They had decided that those cities shall receive beltways (which all did except Scranton) but didn't have the mileage to add them all yet.
Probably pretty hard to verify, but I wonder if the NB Interstate 29 bridge over the Big Sioux River was the first structural collapse of the entire Interstate system ?

I 35 in Minnesota happened in 2007 and I 40 near Webber Falls, OK happened in 2002.
Correction: The 2007 bridge collapse was on I-35W, not just plain I-35.

And a quick Google search says this I-29 bridge collapsed in 1962, so...
Here's a pic of the bridge. Scour dislodged the piers and the bridge was ruined.

Topic bump rather than start a new thread on this topic. I've seen interstate history on a few threads here, but this thread makes the most sense.
My phone news had an interesting, well-written article on the history of Minnesota interstates from a site called streets.mn. The article covers the early history for the entire system, so I decided to include it here rather than place it in the Great Lakes or Central States. I originally saw part two, but I think the entire article is worth reading so I've included links to both parts.
A History of Minnesota's Interstates, Part One (https://streets.mn/2019/03/13/a-history-of-minnestotas-interstates-part-one/)
A History of Minnesota's Interstates, Part Two (https://streets.mn/2019/04/12/a-history-of-minnesotas-interstates-part-two/)
The author of the MN interstate series is an occasional user here, Mdcastle. He recently did a series on (mostly) former US 61 from the Twin Cities to Duluth.
