Opposite multiplexes

[Chicagosuburban]

Multiplexes signed as opposite ways
For example: I-77 and I-81 near Wytheville, VA...you could be going on I-77 north and I-81 south at the same time
One on a local level is US-20 west and IL-72 east, which is also IL-47 north

What are some others?

[agentsteel53]

has anyone ever managed to find a full four-direction multiplex?  three-direction ones are easy enough to find, like the 20/72/47 example.  (which gets bonus points for being three different route classifications!) 

[agentsteel53]

the southeast quadrant of the Boise City, OK rotary (roundabout? traffic circle?  I can never remember which is which) contains US-385 north, US-287 south, US-56 east ... but nothing westbound, alas. 

I'd imagine a true four-way multiplex would show up in a similar context.

Indiana has at least three opposite triple or more m-plexes:
- I-469 North/US 30 West/US 24 East in Fort Wayne
- SR 22 West/US 35 North/SR 19 South between Kokomo and Marion

I-465 east leg in Indy would have:
- I-465 North
- US 31 North
- US 36 East
- US 40 East
- US 52 West
- US 421 North
- SR 37 North
- SR 67 North

The US 19/US 62/PA 58/PA 258 multiplex in Mercer, PA almost meets this.  For half a block, you are travelling south on US 19, north on PA 258 and east on PA 58.  The only problem is US 62 is signed north/south in Pennsylvania, or you would be heading west on US 62 as well.  I took the pictures for Timothy Reichard's site several years ago. http://www.m-plex.com/roads/pamplex/mp_us19_us62_pa58_pa258.html

I believe that Beaufort County has US 17 and US 21.

I've seen and photographed a number of tri-directional concurrencies.

As for all four directions signed on a single piece of roadway, I seem to remember someone posting an example of such on MTR way back when and said phenomenon was observed, I believe, in Massachusetts. I've searched MTR many times trying to find that post, but whoever posted it must have been paranoid and used the old "x-no-archive-yes" header to keep DejaNews from preserving it.

US 72 and AL 20 in Florence

[74/171FAN]

Multiplexes signed as opposite ways
For example: I-77 and I-81 near Wytheville, VA...you could be going on I-77 north and I-81 south at the same time

And also including US 52 and US 11 for a section as well.

One i know of since i drive it anytime i am going to my grandmother's is in Green Lake County WI southwest of Markesan.  South WI 44 and North WI 73 are cosigned going in opposite directions. Actually, WI has a fair amount of these.  In the Wisconsin Dells area, East US 12 and West WI 23 are cosigned.  In Janesville, West WI 11 has a 3 mile cosign with East I-90/39. In Waupun, North Bus US 151 has a short 2 block cosign with South WI 49.

The bypass of Fremont, Ohio allows you to travel EAST on US 6 and US 20, SOUTH on State Route 19, and NORTH on State Route 53 all at the same time.

Add to that I-95 S/MA-128 S and US-1 N in Dedham and Canton MA.

I dont think 4 at once would be possible unless the state had a stupid DOT

I dont think 4 at once would be possible unless the state had a stupid DOT

I can think of about 50 states and one district with DOTs that meet that classification.

US 15 North, US 220 South, and I-180 West in Williamsport, PA is another.

[PAHighways]

Staying in the Commonwealth:

US 119 and PA 36 in the home of the most famous marmot weather forecaster
I-376/US 22/US 30 and Truck US 19 from PA 51 to I-279 in Pittsburgh

In the Ft. Wayne area, you have the brief 2-mile stretch where you have the I-469 North/US-30 West/US-24 East multiplex, and going the other way you have the I-469 South/US-30 East/US-24 West trio.
