largest multiplex

[silverback1065]

What is the largest (in terms of the number of different highways multiplexed) signed multiplex you guys have ever encountered?  (i-465 doesn't count)

US-1/23/301 + GA-4/15/23/121

Wow, GA 23 and US 23 share the same roadway?

Even worse is Brunswick, where US 17 is SR 25 and US 25 is SR 25 Connector: http://usends.com/20-29/025/025.html

It's not signed for U.S. highways, but I-40/I-55 in West Memphis also carries U.S. 61, 64, 70 and 79 for a sex-plex.

Greensboro's "Death Valley" before the Urban Loop was completed. I-85 (mainline at the time), I-40, US 29, US 70, US 220, and US 421 (now removed), which was a wrong-way concurrency with 85/29/220.

I'm curious to know the greatest number of non-Interstates multiplexed onto an Interstate.  Here in Wichita, we have a short stretch of I-135 mutliplexed with one US highway and two state highways (81, 15, 96).

I'm certain I-465 wins here.

I-305 has Business 80, US 50, CA 16 and CA 99.

Doubt it's the biggest winner.

What do the international offerings have?

The best one you can get in Connecticut would be Danbury. Along I-84, between Exits 4 and 7 is a multiplex of I-84/US 6/US 7/US 202. Only recently, did the signing in this section get updated to reflect that idea.

I-30 in Little Rock has 4 US highways multiplexed onto it-65,67,70 and 167.

US 70 isn't duplexed with I-30 through downtown LR and NLR.  It follows University to Asher to Roosevelt to Broadway.

There appears to be some dispute about it. Maps weren't clear, and according to wikipedia(yes, I realize that is not always accurate), US 70 is multiplexed with I-30 through Little Rock, and the route you describe is US 70B. US 70B is also(at least what used to be) signed in the field. But I also realize sometimes what is signed in the field isn't always what is on the books.

[bugo]

US 70 is signed on the surface route.  It was once signed as 70B, but now only a few 70B straggler signs remain.  There was a 70 overhead sign on I-30 at I-530 but it might be gone now.

Although multiplexes do occur in Europe, they're not as common as they are in the United States. Often numbers just have a break in the route. Although most nations do have extensive road numbering systems, road numbering is generally not seen as THE most important way of navigating, we use a combination of control cities and numbers.

I'm sure there are some situations where many E-numbers are multiplexed, for instance on the Budapest beltway, where M0 is multiplexed with E60, E71 and E75. Although it varies by country, E-numbers generally have very little significance in most of Europe. You won't hear them on traffic information unless it's in a country that exclusively uses E-numbers such as Belgium, Sweden, Serbia or Denmark.

Budapest:


Madrid is also known for the road signs with (too) many road numbers on them, but these are mostly indirect road numbers, rather than multiplexes.

Chris,

What the heck is that ground-mounted blue sign on the right side of your Budapest picture?

Hard to tell, it appears to be advertising. It doesn't look like a part of the regular signage. I found the location on Google Maps and the sign is a bit off the road, about 60 m / 200 ft off. This photo shows the back of the sign.

Another seven: US 341/US 129 Alt/SR 26/SR 27/SR 112/SR 230/SR 257 in Hawkinsville, GA.
