Opposite multiplexes

This map shows the RI 114 wrongway self multiplex:

US 1 is blue.
RI 15 is red.
RI 114 is green.

Newberg, Oregon:  Oregon 99W and Oregon 219.

And to throw in a wrench, both 99W and 219 are north-south routes, but while multiplexed in Newberg runs on a west-east street/couplet.  At the west end of the multiplex 219 heads north to Hillsboro while 99W continues west through downtown before turning to the southwest towards McMinnville; at the east end 219 continues east and then south towards St. Paul while 99W heads northeasterly up to Rex Hill and the Portland metropolitan area.

There's also the wrongway self multiplex of Truck US-19 in Pittsburgh. The map can be confusing, but US-19 goes north from Banksville Rd and north on Saw Mill Run Blvd. Truck US-19 goes north on Saw Mill Run Blvd and then north on I-279376.

Not a true opposite, but WB US 270 in Arkansas follows US 71 South at Y City, then turns and follows US 59 North at Acorn.

There is a short opposite in Texarkana with SB US 71 following NB US 67 for 2-3 blocks.

• NY 34 and NY 34B north of Ithaca for about half a mile.
• US 15/220 in Williamsport, PA.  Before I-180 was changed to east-west, it would have been the opposite of US 220, along with US 15.

Southwestern Ohio: US 52 goes wrong-way with US 62 (along with US 68, except that's signed N/S in Ohio).  Actually, US 62 might be signed N/S there too, but probably not in a majority of assemblies.

114 doesn't look quite right. (Why would it turn right and go around the loop when it could just turn left?) I believe the dark green turns at Division to follow the light green.

According to oxlahun at the Clinched Highways project (he did up the Rhode Island highways for the site), it's the official routing.
Agree it's insane.

US 60 wrong-way overlaps itself in Newport News, and it makes sense unlike RI 114.

I'm confused: how does a road overlap itself? 

[Zmapper]

Is there anywhere with a quad wrong way multiplex; that is, on one segment of road you can head north, south, east, and west at the same time?

[NE2]

US 60 wrong-way overlaps itself in Newport News, and it makes sense unlike RI 114.

I'm confused: how does a road overlap itself? 

If one direction of a road carries both directions of the route. In this case, southbound Huntington Avenue between 23rd and 26th Streets carries US 60 east and US 60 west.

I thought someone pointed out a segment of I-465 in one of the first posts in this thread.  But I suppose it doesn't count if only one or two of the several overlapping routes are posted in any single display.

So it's co-signed as both East and West in the same direction?

Even though when I lived there and worked for the city that's how I got back on I-664 when leaving downtown offices, I can't remember if it was signed at all, though a quick check on streetview shows that there is a US 60 shield coming off of 26th St with two banners over it. Then on Huntington Ave southbound signs direct US 60 westbound traffic to turn left on 25th St, which would be a much more logical routing than the one depicted on OpenStreetMap.

Hmmm, you're right (the actual turn sign is misposted just after the intersection on the left side). This is also what the VDOT GIS data shows, which makes the overlap one block instead of three. I've corrected the routing on OSM.

FWIW, Google shows WB US-60 going 26th -> Jefferson -> 28th -> ramp -> 29th -> Warwick.

I think we've shown time and time again that Google is worth diddly squat.

As best as I can tell, Google or their supplier started with TIGER data and its name_* tags to extract route numbers, then automatically made routes continuous by adding extra or removing stray segments. This is why you have, for example, the "Co Rd 532" overlap here: http://maps.google.com/maps?ll=28.280801,-81.407747&spn=0.067271,0.164795&z=14 (CR 532 begins at US 17/92 west of Intercession City and US 192 east of St. Cloud.) In the case of US 60, the algorithm must have given Jefferson-28th-29th as the most likely way to fill the gap.

Here's another one involving US 60:

In Shelbyville, KY US 60 picks up KY 55X (Business - this part just used to be plain KY 55), then about a mile later, picks up KY 53.  US 60 East is KY 55X North and KY 53 South, and US 60 West is KY 55X South and KY 53 North.  The 55X/53 overlap lasts for about 1.5 miles.

[vtk]

US 42 and OH 257 overlap in opposite directiions across the Scioto River near Bellpoint.  Signage doesn't make it obvious though, since there are no reassurance markers for 257 on the overlap section, and directional banners aren't posted on every shield.

US 62 and US 33 overlap the wrong way in downtown Columbus.  However, directional banners for US 62 may be absent or shared with a N/S route in this area.

TCH 1/BC 5/BC 97 through Kamloops


TC-1 East/BC-5 North Kamloops by sagebrushgis, on Flickr

Also, SK 11/2 through Chamberlain (north of Moose Jaw & Regina)

Just a few from down here.

US 441 (S) and FL 19 (N)
FL 61 (N) and FL 363 (S), even though it's for about a block.
FL 263 (unsigned) (S) and US 319 (N)
FL 25 (S) and FL 35 (N)
Alt US 27 (S) and US 41 (N)
And the newest one, US 17 (N) and US 23 (S)

[NE2]

FL 25 (S) and FL 35 (N)

This one's unsigned (I'm not sure if SR 35 is even officially defined here).

[Alps]

The entire state of Maine. There are just so many multiplexes that I can't possibly analyze them all. One I know for certain is ME 17 SB/ME 11-100 NB (and US 202 EB, which is really also NB the way most states sign it).
Edit: Now onto a second one, ME 7 NB/ME 100 SB along US 2 WB in Newport.
