I was noticing that US 90 Business in LA crossing the Mississippi River (Crescent City Connection), has its alignment in a full reverse where US 90 Business EB is actually heading true west and vice versa for WB going true East. In fact the Huey P. Long Bridge can be seen on the horizon as you head into New Orleans, where you just were south of that crossing if you had indeed been traveling US 90 Business EB from conception.
Another is here https://maps.google.com/maps?q=Fort+Lee,+NJ&hl=en&ll=40.859541,-73.974295&spn=0.008049,0.016243&sll=27.698638,-83.804601&sspn=9.563267,16.633301&oq=fort+l&t=h&hnear=Fort+Lee,+Bergen,+New+Jersey&z=16&layer=c&cbll=40.859277,-73.974202&panoid=ifdO0jsrRvvejAB1CPXQaA&cbp=12,1.03,,0,-0.3 In Fort Lee, NJ I-95 does the same after entering NJ from NY heading SB on the interstate you actually head due north as seen by the directional indicator.
How many other places (excluding mountain roads where the roads are aligned very winding due to the topography of the land) have the situation where this happens?
Edit: Had to search, but found the correct word. Topography instead of Tiopary.
Any place a highway crosses over or under itself (e.g. Lincoln Tunnel helix, US 441 in the Smokies, I-74 and I-80 near Rock Island).
I-295 in the Aljo curve nearly does a 180' reverse, and in several areas of 295 between Exit 23 and 31 traffic is going the opposite direction (one can tell as the sun is rising or setting there is several times the sun crosses the path of the roadway, resulting in numerous sunglare issues). The Delaware Memorial Bridge is also a location where SB traffic is actually heading north, and vice versa.
I-25 south heads northwest for a while.
I-64 ends up doing a 270 at the east end, but no directions are signed after the first I-264 junction.
This also happens in a lot of places where the roads parallel winding streams.

for I-74 and I-80, a similar example would be I-95 cloverleafing itself in Canton, MA.
Michigan's M-123 is shaped like an upside down J, so that you're heading due south for its last few miles to its "northern" terminus near Newberry.
They could easily eliminate this by signing it as east-west, or (as I've heard proposed) moving its northern terminus to Whitefish Point and designating another highway from Newberry to Paradise, like an extended M-117. But where's the fun in that?
US 14A in Spearfish has a horribly signed 180 degree reverse...

This article (http://www.theadvertiser.com/article/20130413/NEWS01/304130029/Designs-49-project-begin) reports that Governor Jindal's Interstate 49 South Feasibility and Funding Task Force has recommended that I-49 shields be installed from the Superdome to the Westbank Expressway:
Quote
The task force voted unanimously to ask Gov. Bobby Jindal to start the process with federal highway officials to install signs from the Superdome to the Westbank Expressway designating the roadway as I-49.
(bottom quote from I49 in LA (https://www.aaroads.com/forum/index.php?topic=3124.msg215426#msg215426) thread)
If the I-49 signage is installed, then one would have to initially travel in a southeasterly direction from the "southern terminus" of I-49, on "northbound I-49", in order to eventually get to Kansas City.

California's Route 70 is somewhat in that vein, as it starts out north-south from Route 99 to before Quincy, then heads southwest-northeast (but signed east-west) to Portola, before flattening out in an east-west trajectory.
Surprised that US 101 in Washington hasn't merited a mention yet, or US 6 in Provincetown, MA.
Minor example: Eastbound US 50 near Echo Lake (en route to South Lake Tahoe) runs northwestward for a few miles before continuing on in a northeast direction.

And US-101. It looks like the Olympia-Port Angeles direction is signed northbound, even though it ultimately will take you to Oregon. I'm not sure where the switch is made. (TheStranger beat me to it)
US-321 has a 180-degree shift in signage alone, in Elizabethton, TN. If you leave Elizabethton on US-321 in either direction, you're going southbound. The road itself doesn't make that significant of a turn, and it should be signed east-west west of there.

You're missing it. Just like mountain areas, of course, rivers would be the same. I am talking about rare occurrences where a road that is signed one direction has an encounter of some sort taking it the other way for a brief moment due to other circumstances.
The Crescent City Connection is one of those just like I-95 in Fort Lee, NJ where it interesting turns around 180 for a brief moment to get to where it needs to be not because of mountains, hills, waterways (although even the Mississippi curves here to start the process it still has no bearing on how the engineers constructed this scenario )terrain, and the usual obvious. If anyone counts how many times a river, stream, mountain pass, curve in a ramp, or loop at a grade separation, the answers would be astronomical!
To all users I do not mean directional heading turnarounds such as US 101, and US 321, or M22 in MI and most of all ramp loops or the pigtails on some over and under grade. One where the road literally turns around for reasons other than the norm. US 90 Business is indeed a rarity where such a case happens where its not to do directly with nature and I-95 in New Jersey it was done to spare Leonia, NJ from having a freeway built through it.
The very north end of US 1.

The switch occurs a bit north of WA 104 - it's east-west on the section going through Port Angeles, from what I recall in 1996.
I believe it's more or less at WA 20. The BGS at the end of WA 20 directs you South to Olympia or North to Port Angeles, but if you turn "North", the first reassurance marker says "West".
Route 139 in Massachusetts is an east-west roadway that turns south once it hits the shoreline, then turns back west while still signed as east.
Route 28 is a north-south roadway through most of the state that runs east-west on Cape Cod, then turns north while signed as south once it hits the Cape's "elbow".
What is interesting is Virginia has one on I-64, but does not sign it where it changes back. I believe that I-264 has something to do with it if it not do to sensible thinking, as I-264 is signed E-W in true fashion as it would make for WB I-64 to be running almost parallel with EB I-264 and EB I-64 running the same way as I-264 WB. Remember I-64 does the turnaround thing completely between both interchanges of I-264.
speaking of roads which wrap around Cape Cod... US-6 starts out heading east, then turns south, then west.
the former length of US-6 did a similar thing. south of the Nevada line, it headed south for a while, entering LA (and even having a few southeast trajectories, like the 6/99 multiplex) before entering Long Beach heading south, and then turning east for the last few blocks.
Louisiana is infamous for roads that have no consistent direction. As with the above example, topography plays a role but sometimes the culprit is just non-sensical routing. See LA 27, LA 44, LA 16, LA 112, LA 113, LA 428, LA 606, etc.
I forgot US 1 in Key West, FL where it heads north into its southern terminus at Whitehead and Fleming Streets.
The sensible thing is to actually end it at the southernmost point in the US which is the other direction of its southern end, but somewhere I heard that it has to do with the Monroe County Courthouse being at the location it terminates at present. Apparently at the time of route numbering back in the day, courthouses were chosen as places for highways to terminate at end of line cities for some reason.

You're missing it.
Yes, I too am curious to learn where a road might shift directions to miss a topiary. :bigass:
Until a couple of years ago, the two frontage roads paralleling I-85 between Exit 11 and Exit 16 east of Montgomery were signed as US 80 (paralleling the northbound [actually eastbound] lanes), and AL-126 (paralleling the southbound [actually westbound] lanes). When US 80 was rerouted along I-85, the former US 80 was re-designated as AL-126 so that it basically forms an 11-mile horseshoe route around I-85. The original AL-126 was correctly signed as east-west, but the "new" 126 is signed as west-east. Fortunately, neither route is significantly traveled, so I doubt few motorists are confused.

The Delaware Memorial Bridge is also a location where SB traffic is actually heading north, and vice versa.
I believe the Fort McHenry Tunnel is the same way, as it bends underneath the Baltimore Harbor.
On Ohio's Marblehead peninsula OH 163 wraps around the tip of the peninsula and has a 3 mile section of wrong way alignment leading to it's eastern terminus. The OH 163 designation used to end right at the peninsula's easternmost tip just south of the Marblehead Lighthouse, which is what Google still shows, but sometime in the past decade an extra section of Bayshore road has been signed at 163 as far as Hartshorn Rd.

US-41 in Michigan doesn't make a full 180° mis-alignment, but does travel due east at some points, only to travel due west later on. While going east/west, there are spots where it angles in the opposite direction from what is signed.
NM-161 NE of Las Vegas. It begins on NM-518, heads southeastward to I-25, then turns northeast to parallel the freeway. It then turns back north-northwest to end at Fort Union National Monument. Both exits with I-25 are marked the same. That latter segment was formerly NM-477, but it became the extension of 161 in the 1988 renumbering.
M-29 around Anchor Bay and Harsen's Island between Fair Haven and Pearl Beach.
I-93 on both ends has it turn so "north" or "south" is the wrong way. It's not quite 180 degrees though.
MA 127 doee a full circle around Cape Ann. Comes a few blocks from ending at itself too.
EB I-80 at the eastern terminus of I-84 in Utah is actually headed northwest.
NB US 101 between Woodland Hills and Calabasas, CA heads southwest
NB CA 14 through Acton heads southeast
SB I-280 at its southern terminus in San Jose is headed northeast
NB CA 1 in Santa Cruz is also headed in the wrong direction
SB CA 183 at its southern terminus in Salinas is also headed due north, with no connections to SB 101
AK-1 is signed mostly east-west (with some odd North-South markers around Anchorage) but at its eastern end in Homer, it is going due west.
US 101 in downtown Santa Barbara also has a brief 180º shift
On I-84 in CT just east of Exit 30, there is a place where eastbound traffic is headed west, and vice versa. Also, there are a few roads that loop south of US 1, loop back over, then head north. While the loop starts out heading south toward LI Sound, it is actually marked North. CT 154 and CT 213 are examples of this. Also, a switchback on CT 162 in West Haven near I-95 Exit 42 where you're heading opposite.

A skier from Montreal going to Mont Orford wants to head north onto the beginning of Hwy 141 southbound. The highway makes a wide turn to head south shortly after the ski area.

In fact the Huey P. Long Bridge can be seen on the horizon as you head into New Orleans, where you just were south of that crossing if you had indeed been traveling US 90 Business EB from conception.
I don't know if you payed attention, but the Huey P is setup exactly the same. EB US 90 crosses the Huey P in a westerly direction, although it isn't due west, before turning back east to head into the city. Also, if you look to your right as you cross over Tulane Ave on the I-10 in the business district you can see I-10 crossing the same street again headed in the opposite direction two miles in the distance and vice versa.
WI 13 goes north from US 2 in the Ashland area, but as it turns west towards Superior, there are some southbound segments.

LA 151 is part of the etc. It's almost 70 miles long, starting in Arcadia running northbound. After a few sharp turns, you end up eastbound through Dubach. Another couple of sharp turns later, you're headed southbound going through Calhoun. It crosses I-20 twice, exits 69 & 101...a distance of 32 miles. The DOTD only puts directional banners over the shield in Arcadia and at the junction with LA 146 @ Goose Creek.
