Changing direction

[usends]

So, back to the OP's question: do these myriad examples imply that there are no guidelines that discourage signed direction changes?

Out of curiosity, is US 67 signed east-west anywhere in Texas?

And a historic/modern example:

Originally, US 6 was signed east-west in its entirety, even in the north-south segment in California from Long Beach northward.  When the segment south of Bishop was removed, US 6 received one "US 6 East - Provincetown" distance sign at the new western terminus, but is now signed north-south in the short segment within the state!

US 6... is now signed north-south in the short segment within [California]!

Inconsistently, though:

usends: Thanks for the photo!  Of course, a similar dilemma exists with US 57 in Texas - signed north-south for continuity with Mexico route 57, but east-west for its entire run in the US.

WIS 23 is signed N-S from Wis Dells to WIS 11 and E-W from WIS Dells to lake Michigan (Sheboygan)

US 52 is signed N-S in MN and IA, but E-W in ND and IL.

FL 826, the Palmetto Expressway in Miami-Dade County is a north-south route from its southern terminus at US 1 up to just north of NW 154 Street.  It then bends 90 degrees to the east and becomes an east-west expressway just before the exit for NW 67 Avenue until it arrives at the massive Golden Glades interchange at US 441, the Florida's Turnpike, FL 9 and Interstate 95.  East-west FL 826 continues through northern Miami-Dade County to the beach at FL A1A.

Also I-196 and several state routes in Michigan.  I-196 is a long spur off from I-96 and goes more or less due west thru Grand Rapids, then goes nearly due south thru the suburbs (but is still signed as an E/W route).  Upon entering Ottawa County it ventures somewhat southwesterly toward Holland and then just west of exit 49 it is signed as a N/S route.  Shortly thereafter it duplexes with US-31 and heads basically due south where it ends at I-94 in the Benton Harbor/St Joseph area.

In Michigan, M-22, M-123, and I-69 change direction in addition to I-196. M-22 loops around the Leelanau Peninsula venturing north from Manistee through the Sleeping Bear Dunes National Lakeshore and up to Northport. There it turns south along the West Arm of Grand Traverse Bay to terminate in Traverse City.

M-123 starts north of St. Ignace, crosses M-28 and runs north to Paradise. There it turns west and south through the Tahquamenon Falls State Park and terminates south of Newberry at M-28. (There was an internal MDOT proposal to transfer Whitefish Point Road north of Paradise to MDTO control. The section of M-123 between Newberry and Paradise would have been part of an extended M-117.)

I-69 is signed E-W from Lansing to Port Huron, and N-S from Lansing to Indiana.

Two honorable mentions: US 41 and US 31. Through Marquette County, the street addresses change signed directions west of Marquette. Addresses in City of Marquette are US 41 South, but in Marquette Township, they are US 41 West. Negaunee addresses are US 41 East or US 41 West. The highway direction does not change though. In Traverse City, US 31 addresses are South and East. Actually, some addresses for US 31 in the retail corridor in Garfield Township are N. US 31 South, and in the Chums Corners area are just US 31 South.

I'm surprised nobody mentioned the Capital Beltway (I-495) around Washington D.C. It changes direction several times as it circles the region. In Virginia the change point is at the big rebuilt Springfield Interchange. If you're going North on I-95 you can then go "North" on the Beltway towards Tysons Corner or "East" which is concurrently I-95 "North" to Baltimore.
