highest number of multiplexes

[bassoon1986]

So I'm fairly new to this site and it may have been posted before, but where are places where there are many highways multiplexed and preferably signed? I'd wager that the loop with US 80 in Montgomery AL would have a lot, especially if the old Alabama highway numbers are signed. I know that I 20/I 59/US 11/US 80/ MS 19 in Meridian has 5 all signed. Where are there examples of more?

at the separation of these routes, 6 are signed



yes, that should be US-41.  Silly Georgia.

There are seven in Folkston, GA:

Kentucky's champion is five -- a short stretch of US 23, US 119, US 460, KY 80 and KY 1426 in Pikeville.

Sure wish Indianapolis signed all of the concurrencies (I am beginning to dislike the term multiplex) on I-465.

Join the club. (Though I find concurrency cumbersome - overlap sounds much better.)

TX has occasional 3-way overlaps but few that are more than that.  One exception is this 4-route overlap (US 82-183-277-283) SW of Wichita Falls and down to Seymour.

That could easily go on the "worst of road signs" thread. Looks like someone having an asthma attack could blow that down.

[apeman33]

The only two in Kansas I can think of with more than three are I-35/U.S. 50-56-169 for a while from Olathe to I-435 and the very brief I-135/U.S. 81/K-15-96 one in Wichita.

Okay, three. I-70/U.S. 24-75/K-4 for a bit in Topeka.

[Quillz]

Doesn't exist anymore, but I think the most California ever had was a 60/70/99 multiplex. One of the reasons that led to the 1964 renumbering, I think.

[NE2]

That's I-10/US 60/70/99, buddy.

[roadfro]

Of the concurrencies pictured above, how many of the state highways overlap the US routes so as to be completely redundant? Or do they really just not have enough roads to route all the different highways on?

I would imagine that signing so many overlapping highways would lead to driver confusion...

Of the concurrencies pictured above, how many of the state highways overlap the US routes so as to be completely redundant? Or do they really just not have enough roads to route all the different highways on?

For the Georgia ones pictured:

First photo:
GA 49 stands on its own for most of its routing.
GA 11 is concurrent with US 129 from Gray to the Florida state line; GA 22 is concurrent with US 129 from Gray to Macon and then with US 80 from Macon to the Alabama state line.  Truncating both to Gray would remove them from that assembly.

Second photo:
GA 4 is entirely concurrent with US 1 and could simply be removed.
GA 15 stands alone for almost its entire route south of Athens.  Could be truncated at US 129/441 on the north end and at US 1/23 on the south end, which would just leave a ~25-mile concurrency with US 1 north of Baxley; this would remove it from Folkston.
GA 23 is concurrent with US 301 and/or GA 121 from the Florida state line to just north of I-16.  Could be truncated to Metter, which would remove it from this assembly (and also remove its absurd concurrency with US 23).
GA 121 is concurrent with US 25 from Millen northward.  It's part of a multistate route 121 with Florida and South Carolina; my preferred solution would be simply to upgrade it in place to a US route.  It could even keep its number; unlike the proposed US 121 in West Virginia, SC 121 actually intersects US 21.

Perhaps in instances such as these, they could use a single state route shield that lists all the concurrent numbers, similar to that "US 1-9" shield you see in a few states.

Doesn't exist anymore, but I think the most California ever had was a 60/70/99 multiplex. One of the reasons that led to the 1964 renumbering, I think.

There was US 66/91/395 and I-15 between San Bernardino and Hesperia as well.

Today's largest signed concurrency in California is US 50/Business 80/Route 99 in Sacramento, with implied routing of Route 16 and the only-acknowleged-by-FHWA I-305.

[Duke87]

Connecticut's max is four: I-84/US 6/US 7/US 202

There are a few threes:
I-84/US 6/US 44
US 5/CT 15/CT 287
US 44/CT 8/CT 183
US 202/CT 10/CT 189

[NWI_Irish96]

It's not signed, but there is a stretch of I-465 in Indianapolis that also carries I-74, US31, US36, US40, US52, US421, IN37, and IN67

[Ian]

That could easily go on the "worst of road signs" thread. Looks like someone having an asthma attack could blow that down.

The signs themselves are fine, but I wholeheartedly agree with what you said about the gantry itself!

Half of that multiplex has unsigned CA-51 as well, right?

I agree, that set of signs looks pitiful.

I think I like concurrency better than multiplex, too. I was just looking for the right word when I made the title and that's the only one that came to mind

[OracleUsr]

Until US 421 was routed along I-73, you had one in Greensboro that was:

I-40,I-85Bus, US 29,US 70, US 220, US 421

Still, 5 is pretty impressive.

I guess this technically counts. I-49, US 167, and Bypass US 71 in Alexandria, LA

In Minden, it isn't signed with all 3, but there is US 79/US 80/LA 159. This intersection shows where the concurrency starts. There is a JCT US 79/80 sign before the intersection but nothing when you reach the stop sign.

No.  Route 51 is only concurrent with Business 80 (at least as far as I know - the FHWA I-305 designation was extended some time in the 90s, and my guess is that it might cover the 1960s interstate-standard segment of Route 51/Business 80 from US 50/Route 99 to E Street, but I can't confirm that).

Wow, Corco...WHY were you in Farmerville, LA??  Yeah, there's our newer black state highway signs. I liked the old green ones better. I'd be happier though if they were black statewide and not a mix of everything

[Ian]

Yeah, there's our newer black state highway signs. I liked the old green ones better.

Agreed.

Random question: does Louisiana still use the narrow 2-digit sized route shields for 3/4 digit routes? Or do they use wider 3-digit sized shields for those?
