Routes That Intersect out of Configuration

How many instances can you think of that any numbered highway with a cardinal direction posted with it turns, veers or loops back around to where the traffic is now not facing that cardinal direction and then intersects another highway with the same situation happening.  Confused?  Highway A is a north-south route, and the highway has a bend in it so that northbound traffic his now heading east for a bit.  It then intersects Highway B, which is an east-west highway that earlier also had a bend so that westbound traffic in now facing north.  so to turn from North Highway A to West Highway B, the traveler will in reality turn from facing east to facing north.  It doesn't have to be a 90 revolution, it could be a situation where northbound traffic is now facing southbound.

In Santa Fe, I-25 and US 84 have an intersection.  US 84 is obviously an east-west route, but leaving I-25, US 84 is almost a directly north-south routing, and I-25 at this point is heading east-west.  Then shortly after that I-25 bends again and the northbound direction is actually facing south. 

I guess backward concurrencies would also count.

If I am properly understanding the question...

Dan Ryan (I-90/94) at Stevenson (I-55) Expressways in Chicago

I-55 is much more E-W and I-90/94 is much more N-S at their junction

In Beloit, WI, near the Illinois border, I-43 begins at I-90; at that point, I-90 runs north-south, while I-43 takes off heading northeast toward Milwaukee - albeit more east than north.

Much more?  I-90/I-94 in that area is the most north-south highway in the system.

Lake Shore Drive/US 41 is at least signed North-South. Granted, it is not Freeway the whole way and also has Truck Restrictions, and its only direct connection to the Interstate system is I-55

I figured this out as a kid years ago, but it makes perfect sense why Traffic Reports refer to the Chicago Radial Expressway route directions as "Inbound"  and "Outbound"  due to the mental gymnastics one has to do, with E-W signed routes going N-S and N-S signed routes going E-W

At least I-55's immediate predecessor, US 66, was signed E-W.

I will not call for a fictional renumbering in this thread

US 285, signed north-south, runs mostly east-west from Kenosha Pass to its terminus at I-25 in Denver. In Morrison, US 285 has two consecutive interchanges that meet this criteria: CO-8 (US 285's old routing) and C-470 (the southwestern bypass of Denver), both of which are signed east-west and run north-south where they connect to US 285.
So many miles and so many roads

There are many examples of this in Upstate South Carolina:

I-85 and I-26
I-26 and US 29
I-85 and SC 14
I-85 and SC 20
I-26 and SC 11

And no doubt many more...

Technicality?:
I-5 at OR 99/140
I-5 is turning from a NW (nb)/SE (sb) angle to W/E, and OR 99 is doing the same at the interchange. OR 140, meanwhile, is an E/W route that continues from the interchange in a NW direction before doing a hard turn to the east at Bear Creek.
To make it even more confusing, OR 140 isn't yet signed from I-5 or at the interchange as it's a recent extension from OR 62.

Related: OR 62, an E/W route that essentially runs N/S then S/N over its route -- which gives the bonus of starting its N/S reversal at OR 230, which itself is an E/W route running almost due north from OR 62

Yes, but US 41 runs east-west on Foster, where it intersects the east terminus of US 14, which goes north-south at that point.  Both highways are "rotated" 90 degrees, but one is clockwise and one is counterclockwise.

If I'm reading the OP right, then the New York examples should work:

I-90 (signed E/W, running N/S) at I-190 (signed N/S, running E/W) in Cheektowaga: https://goo.gl/maps/aS3T4MLnqeE71jNG8 (Well, this is more of a partial example, but whatever.)
US 20 (signed E/W, running N/S) at both NY 16 and NY 400 (both signed N/S, running E/W) in West Seneca: https://goo.gl/maps/A37MJhkaoLNZT9wq6
I-86 (signed E/W, running N/S) at NY 54 (signed N/S, running E/W) in Bath: https://goo.gl/maps/KqSd79HfZb8JSE8K9
I-86 (signed E/W, running N/S) at NY 226 (signed N/S, running E/W) in Savona: https://goo.gl/maps/TFUwCuzCqnqVMnXB7
I-490 (signed E/W, running N/S) at NY 96 (signed N/S, running E/W) in Perinton: https://goo.gl/maps/EcXxQEKsQEN5P9VXA

Below are "compass breaker" intersections where (for example) you are facing north, and east is to the left instead of to the right.

On I-95 NB in Groton, CT, you go left to get onto CT 184 EB -- and these roads stay apart for another 15 miles. In other words, 184 east is more "northy" than 95 north.

In South Windsor, CT 30 NB and CT 74 EB used to do the same thing. In Manchester, CT 30 still does so with I-84.

US 1 "north/south" going east/west in CT could have a lot of these with the small loops roads, but the state tends to mark 215, 213, 146, etc. at these intersections with no directional banner.

There is a "south straight, west to the left" situation at US 1 / CT 142 in Branford.

At US 1 SB / CT 162 WB in Orange, ConnDOT avoids the situation by just marking 162 (incorrectly) as EB: https://goo.gl/maps/xKvy3pfzf5YAy2EU9

CT 130 EB goes north of US 1 NB and I-95 NB in sections.

Since backward concurrencies count...

I-77 and I-81 have a backwards concurrency in Wytheville, VA

US-321 and US-441 are backwards in Sevier County, TN between Pigeon Forge and Gatlinburg

US 1 and ME 9 also does that for one of its several intersections.

Where I-295 meets I-76 in NJ, 295 is extremely East-West at that point; I-76 is almost perfectly North/South.

Ketchup99

Here in State College we have a mess like this. US Route 322 and PA Route 26 used to be the main routes through town, but 322 was bypassed in the 1980s. So US 322 Business is signed east-west, like the parent highway, but "west" is North Atherton St and "east" is South Atherton St. Likewise, PA 26 is signed north-south, but "north" is East College Ave and "south" is West College Ave. Their intersection downtown therefore meets the requirements somewhat (it's a 45 degree angle).

But the best part is that ever since I-99 came to town, it's been concurrent with US 322 (a true east-west freeway at this point) along the north part of town, before curving south. So getting from downtown to the highway entails heading to northern State College on North Atherton Street aka US 322 Business West, which leads directly into I-99 South. All the directions are messed up... doesn't help that PA 45, running parallel to PA 26, IS signed east-west in the way people here think of direction.

US 12/20/45 at IL Route 171 in Willow Springs perhaps? Route 171 runs more ENE-WSW but is signed N-S. US 12/20 runs N-S but is signed E-W.

US 89

US 30 and US 89 in Montpelier, Idaho. Both routes are fully perpendicular to their expected orientations: eastbound US 30 is south, and northbound US 89 is east aside from a 2-block overlap on US 30.

This is a bit of a twist: How about the Eastern (Northern) terminus of I-44? I-44 East becomes I-70 West, while in a N-S orientation in Downtown St Louis

I-44 East with a control of Kansas City in Downtown St Louis is funny, almost bad

And the western terminus of I-44 with I-44 west feeding SE into South US-287, and North US-287 heads due west out of the interchange.

(snip)
At the recently-reconfigured meeting of I-95, I-276/PA Turnpike and (now) I-295, I-95 North heads almost due east from the interchange while I-295 East heads NNE. (I-95 South and I-276 make sense.)

KC could easily be shifted to 64 to replace the Wentzville control city (an oddly local one since everything else is Tulsa, Memphis, Chicago, etc.) and the 44 east (former 70 east) could be shifted to "Airport" or even "St Charles."

44 East north of the PSB is former 70 West not East. I understand why 44 was used when the Stan Span opened and 70 was routed over the new bridge – 44 was sitting there available to be extended further north. Just makes it a bit awkward that 44 East becomes 70 West. The BGSs do sign 44 East To 70 West: Kansas City

I prefer Minneapolis for the I-64 West control after entering St Louis on the PSB – let MoDOT acknowledge the existence of the AotS

Personally, if I were MoDOT, I would have had the former section of I-70 designated as I-570 or I-164 - neither of those exist in Missouri yet.

2 cases in Iowa, that I have figured out:
1. I-74 and US 67 in Bettendorf
2. IA 14 and US 18 on the west edge of Charles City.

I-81/US 22 interchange north of Harrisburg, PA.  I-81 (signed North-South) goes E-W and US 22 (signed East-West) goes N-S through the interchange.
VA 164/VA 141 interchange in Portsmouth, VA.  VA 164 (E-W) is N-S through the interchange and VA 141 (N-S) departs the interchange to the east.
US 11/NY 276 intersection in Champlain, NY.  US 11 (N-S) goes E-W through the intersection and NY 276 (E-W) leaves the intersection to the north.
