The 35E/35W finally makes sense! This was fun
The I-35 splits are actually a holdover from an old AASHTO policy. Three-digit interstates (3DIs) weren’t always the only way to designate an offshoot of a 2DI; rather, the old interstate highway plans from the 1950s were littered with interstates that had directional suffixes at the ends. For example, I-15 in part of southern California was once called I-15W and its current spur, I-215, was once I-15E. In 1957, I-15W simply became I-15 and I-15E became I-215 in 1982.
The suffixes proved to be a bit confusing because their directions did not correspond to the direction of travel (if you passed a sign saying you were traveling north on I-15W, it would no doubt confuse some people) so AASHTO, the American Association of State Highway and Transportation Officials, abolished all of them in 1980 with the exception of I-35’s two splits in the Twin Cities and the DFW Metroplex. I-69 is more recent, its three suffixed routes were designated between 2011 and 2014, and as such managed to get exceptions from the AASHTO policy.
@dbr opx 69c, no 35c
Thanks Andy!
i must not travel alot because i thought it was perfectly reasonable all this time
@Alex Cervantes As a DFW resident I was thinking the same! No idea it did that in Minnesota as well
I like how CGP Grey videos follow a formula of: 1. find an interesting topic to educate the population2. almost have an existential crisis trying to piece together all the exceptions and inconsistent history to the concept previously discussed
Even more, Grey picks up a topic you would never believe it was interesting until he uses his magic on it.
You literally copied this comment from another one that HAD correctly pressed the enter key, but just decided not to bother.
What do you mean “almost”?
@Orillion123456 To be fair, when it comes to humans, it is really quite rare for things to not be a rabbit hole. Either a system is old enough to have developed internalized exceptions, or it’s new enough that not everything has been thought through yet. Those holes that haven’t quite been thought through yet are generally the reason most of those exceptions came to be, so if a system isn’t one or the other, that’s probably because it’s in the transitional stage where it’s both.
There are a few topics he’s picked out that are pretty clear and unmuddled – Hexagons are the Bestagons, for instance. Notably about geometry, not people, thus avoiding the messiness that is inherent to people.
Yeah, he never picks any topics that have a straightforward reasonable answer. It’s always a rabbit hole of many “wait a minute”s and “but why? nobody knows”s stacked on top of each other.
Cgp grey is type of person that when gets annoyed by something not making sense instead of giving up makes a youtube video to educate us all. He’s an educational Angel
And winds down a rabbit hole that gives us the history of Tiffany ๐คฃ
It’s so we can share his annoyance and misery
“I already cut so many from the script, you wouldn’t believe it…”
Grey, you made a 21-minute video explaining why one particular detail didn’t make it into a 9-minute video and gave you sleepless nights for the better part of a year. We believe it.
@Taylor Skaalrud “The Tiffany Incident” ๐
That was the Tiffany incident, no?
Hell I’d take a library of videos containing all the intricacies
Release the “Interstate’s Forgotten Code” CGP Grey extended cut now!
A fine return to form for the channel, well done!
@DJ Diarrhea I think Tiffany broke him for awhile.
@Eragonawesome well he aims for abouts one a month
@The Bear Geek yeah but it’s been a while since an upload and Grey likes to try and do about 1 every 6 months at least if I’m remembering rightly
When was it even out of form? His last video was the Tiffany Video. Right?
@DJ Diarrhea wait it wasn’t uploaded a couple weeks ago??
Time is a weird soup
If someone has asked me yesterday “Hey, would you care to learn about the American interstates?”, I would’ve probably said no, but CGP Grey always seems to be able to take any subject and make it interesting and intriguing.
German Autobahns have a similar system. Even numbers are west-east and odd numbers north-south. The higher the number, the more insignificant (shorter) that Autobahn
Not too different from here in Australia where the national highway is route 1, and shorter highways count up from there (more or less)
The most significant Autobahn is Kraftwerk’s Autobahn.
Look up the International E-road network, which the Autobahn is part of.
@Ugly German Truths yeah I believe it took him nearly 2 weeks to cross the country which he absolutely hated. Now itโs only a couple of days.
@Tim LeCount Also Ike had to move a lot pre war, due to being an officer that constantly was sent to another post and he LOATHED the old system without interconnecting highways across the whole continent. The Interstate project is a bit of a combination of both this loathing and his experiences in Europe.
As a Minnesotan who grew up near the Twin Cities, I can safely say that I35 splits into east and west because neither of the cities wanted to bypass the other. Like a Canadian standoff where youโre holding doors open for each other.
Yup, this is such a Minnesotan thing to do. Fits 100% with the predominant driving style here.
A moment of silence for everyone who watched this whole thing waiting for Grey to mention their specific interstate, but he never did.
was very satisfied when maryland got its own segment
Mine was mentioned twice! I-70 and I-55!
@a Throwaway Not KSC, it’s Daytona on the other end (quite a bit north of KSC.) In fact, I4 is practically 45 degrees, and is mostly north/south through Orlando itself, so the even-ness confused me as a kid: to go north on I4, you want I4 East.
I didn’t get mine ;( (I81)
No I-17. The intrastate that connects I-10 and I-40 here in AZ ๐
As a Pennsylvanian I appreciate the shout out to I-99.
@Hunty2022 yeah but he only shouted out maryland’s 395
Absolutely
Seconded.
@Brandon Weller You need to get out more, my friend! 70 or 75 mph limits are practically universal on Interstates west of the Mississippi River. Many rural US and state highways in western and southern states also have 70 or 75 mph limits. Vast stretches of I-10 and I-20 in West Texas boast 80mph speed limits. The highest posted speed limit in the USA is found on the Texas 130 tollway between Austin and Seguin at 85mph.
