Title: Consecutive Interstates
Post by: andrewkbrown on February 21, 2010, 08:41:58 PM
How many instances exist where consecutively numbers interstates intercsect?

I know of I-70/I-71 in Columbus, I-74/I-75 in Cincinnati, and I-76/I-77 in Akron.

3 in Ohio. Any other state with as many, or for that matter, any other state with consecutive pairs of consecutive junctions like 74/75 and 76/77?

I-73 and I-74 in NC.

Mercer, PA -- I-79 & I-80

Also in PA -- I-80 & I-81

The network beat me to these:
I-79 and I-80 in Western PA near Mercer

I-80 and I-81 in Eastern PA near Hazleton

Also:
I-74 ends at I-75 in Cincinnati, OH

I-90 and I-91 in Springfield, MA

I-64 and I-65 in Louisville, KY

when I-69 is extended, it and I-70 will intersect around Indianapolis

when completed I-86 will meet I-87 in New York

if Kentucky's pipe dream comes true I-65 and I-66 near Bowling Green

Close but no cigar:
I-87 and I-88 in the Albany, Schenectady, Troy, NY area

Well everyone has gotten all the interstates I was going to say, but two US routes I know of that do it, is when US 1 and US 2 meet and even multiplex in Houlton, Maine.

I-8 and 10 in AZ.

It's fairly common for US routes. Before the four-lane US 60 was built in Sikeston, Mo., three consecutively-numbered routes (60, 61 and 62) met in downtown. Now they meet south of downtown, and there is a combined routing of Business US 60, US 61 and US 61.

US 23, 24 and 25 did this in Toledo, Ohio before the truncation of US 25.

And I-8 and I-10 above ... what about I-9?  :pan:

If the Vegas to Phoenix pipe dream is realized, I-10 and I-11 should connect.

US 270 and 271 in Wister, OK.  This is probably the highest numbered consecutive US highway duplex in the country.

Complete list, so far as I can tell...

Current:
A1/A2 (Tok, AK)
PR1/PR2 (San Juan, PR)
PR1/PR2 (Ponce, PR)
H1/H2 (Pearl City, HI)
64/65 (Louisville, KY)
70/71 (Columbus, OH)
73/74 (long multiplex in NC)
74/75 (Cincinnati, OH)
76/77 (multiplex in Akron, OH)
79/80 (near Grove City, PA)
80/81  (near Hazelton, PA)
90/91 (Springfield, MA)

Planned:
69/70 (east of Indianapolis, IN)
86/87 (Harriman, NY)

So, that's 12 existing plus 2 more planned.

Since these "interstates" are not signed, should they count?

Actually, I first thought about this over Christmas as I was headed to meet up with AlpsROADS and dougtone.  I had gone through the two I-80 junctions just a couple of days apart.  But, in part, due to being on vacation, I didn't remember to post this back then.

Quote from: rickmastfan67FAIL. :P lol.

The only reason this works is because I-9 doesn't exist yet, thus making I-8 and I-10 consecutive. (Ok, it's an admitted stretch, because with that logic, you could say I-5 and I-8 in San Diego are consecutive [no I-6 or 7]).

Yeah -- you can't even use the I-8/10 argument with that one as I-91 and I-93 beg to strongly differ.

From MTR threads gone by, prior to Ohio doing away with US 21 & 25, one could consecutively driven US 19 (starting in PA), 20, 21, 22, 23, 24, & 25

So what is the biggest difference between the numbers of intersecting interstates where there are no interstates with numbers in between?

I could be mistaken.

But, if I'm not, a quick look at my list of used and unused 2di points me towards I-30 which meets I-35E and I-35W in Dallas-Fort Worth.

The designation hasn't reached that far yet, but I-86 will intersect I-87 eventually.

Was just thinking about this topic this morning in relation to the current traffic mess in Louisville and the handy dandy search feature helped to not duplicate a thread. 

Has anybody clinched all of these intersections?  How about just the continental US ones?

I've done all of those, except the ones on Puerto Rico.  I've been on a different segment of Future 73/74, but I think doing any single point on the multiplex should count for the purposes of this.

I can think of multiple cases of consecutively-numbered 3dis meeting, but given the way the numbering system is supposed to work I suppose that doesn't count as remarkable.

I don't think a difference of 100 counts as consecutive.

Good point, I guess, depending on how you define it. Massive brain fart there on my part.

misc.transport.road, the Usenet newsgroup where many of us got started talking about roads.

It's still in existence today, but many of the participants here and on the Yahoo roads groups who used to participate have abandoned it because of posters like Carl Rogers and Randy Hersh.
