Roads going the exact opposite direction that they're nominally signed for?

[hbelkins]

WV state route 62 between Mount Alto and Mason is real head scratcher. 62 actually has an intersection and a concurrency with state route 2 that has the 2 roads signed together in opposite directions around Point Pleasant.

That came about due to the re-routing of US 33 onto the bridge at Ravenswood.

PA 61 in Sunbury when it runs with PA 147 is a wrong way concurrency, but PA 61 North is indeed running South, and the reverse.

US 209 between Jim Thorpe and Lehighton runs almost due South when traveling NB on 209

I-4 in Orlando was what originally came to mind for this...

In Victoria, US 59 northbound goes southeast for a period of time, instead of northeast.

Also, US 59 southbound in Laredo actually goes northwest on the Bob Bullock Loop. Probably the most extreme example in Texas.

I saw that US 1 near Calais, ME was mentioned, but there are also multiple places near its northern terminus where US 1 South goes due north and vice-versa.  Here's the first one in Fort Kent, complete with a South 1 sign visible while the camera is pointed due north:

There are several more a few miles down the road between Frenchville and Madawaska.

Isn't the Southern terminus of US-1 the same way? Aren't you heading due north in Key West as you approach "Mile 0" on "South US-1"?

Northwest. Doesn't quite make the full 180 degree turn.

WV 62 doesn't appear to make much sense at all. It runs from South Charleston to Ripley via Point Pleasant and Mason

WV-62 used to be a short route along the Ohio River between Point Pleasant and Mason, whereas WV-2 bypassed the bend.  It's been discussed here many times in different threads, but WV-62 was extended to North Charleston over the former US-35 after completion of the replacement Silver Memorial Bridge in 1969 (so-called revenge of the Mothman).  The WV-62 was extended on the other end in 2004 (see the post from H.B. Elkins above).  The DOH should have ended the WV-62 at Mount Alto, extended WV-331 to Ripley and downgraded the other section of US-33 to a secondary.  I don't know the history, but US-33 flipped back-and-forth between the Ripley Road route to the north side of Millwood and the Mount Alto cutoff several times in the past.  But they've always posted both sides as State Routes no matter where US-33 was located.  But it doesn't make so much sense now.

I-5 near Rogue River, Oregon:
From mp 43-46, and again from mp 49-50

[JCinSummerfield]

US-23 in Toledo, OH, where it is signed with I-75.  Also, M-48 in Pickford, MI.

The now Sheppard's hook of NJ I-295.

East of Effingham, KS, South US 159 briefly turns due north.

[JayhawkCO]

Lots of examples in Colorado with switchbacks.  CO5 and US40 through Berthoud Pass come immediately to mind.

New Interstate 11 east of Boulder City, Nevada, has South I-11 going due north and vice-versa.
