Driving your state's perimeter

[tchafe1978]

Wisconsin was fairly simple compared to some of the more irregularly shaped states, or the more rural ones. It's a lot harder than it looks!

[oscar]

California is essentially also impossible also given the lack of roadways on the Oregon State Line in the Trinity Mountains that would require crossing the state line.

OTOH, some parts of California's perimeter are really easy, especially compared to some other states. A combination of US 101, CA 1, I-5 , and CA 75 is a pretty good approximation of the western boundary. For the southern boundary, CA 905, back to CA 94, then to I-8, CA 98, and back to I-8, US 95 is pretty good for the boundary with Arizona, though you'd need to use US 95 on the Arizona side between I-8 and I-10, and AZ 95 along Lake Havasu would better approximate the border than US 95 north of I-10. US 395 follows much of the rest of the border with Nevada.

Wisconsin was fairly simple compared to some of the more irregularly shaped states, or the more rural ones. It's a lot harder than it looks!

That it is.  Michigan requires three different locations where the same road is used to go both directions.

1. Mackinac Bridge (I-75)
2. Portage Lake Lift Bridge (US-41/M-26)
3. US-41/M-26 between Calumet and Phoenix

Two of these are because that's the only bridge connecting an area to another area.

Let's see if I can figure out Georgia (trying to most closely mimic the border, not necessarily get the closest to it distance-wise, and staying inside the state with one minor exception).

Start in the southwest corner at the intersection of GA 39 and GA 253 near Lake Seminole.

This part of the Wisconsin perimeter trip would be pretty nice for people driving from the Chicago area to Door County.  It would take awhile but you would get to see just about every city and town that is on Lake Michigan.

WI 165 East to WI 32 in Kenosha,
WI 32 North to WI 794/I-794 in St. Francis,
WI 794/I-794 North to WI 32 in Milwaukee,
WI 32 North to I-43/WI 32/57 in Bayside,
I-43/WI 32/57 North to WI 32 in Port Washington,
WI 32 N to I-43,
I-43 North to WI 28 in Sheboygan,
WI 28 East to WI 42,
WI 42 North to I-43,
I-43 North to US 151 in Manitowoc,
US 151 North to US 10,
US 10 West to WI 42,
WI 42 North to WI 57,
WI 42/57 North to WI 57,
WI 57 North to WI 42 North,
turning around at the end of WI 42 in Door County back south

And if you were starting out in Chicago you could add this portion of the IL perimeter trip to hook up with with WI because you wouldn't want to miss the Amstutz Expressway piece.
* US 41 from US 14 to IL 176
* IL 176 from US 41 to IL 131
* IL 131 from IL 176 to IL 137
* IL 137 from IL 176 to end at IL 173
(keep going north on IL 137 to the state line where it becomes WI 32, skip the first WI step above)

US 395 follows much of the rest of the border with Nevada.

Let's get specific, starting close to the NE corner at Alturas and heading clockwise:

     395 south to 70, 70 west to 49, 49 south to 89, 89 south to 267, 267 south to 28
     28 west to 89,  89 south to 395,  395 south to 120,  120 east to 6,  6 south to 395
     395 south to 136,  136 east to 190,  190 east to 127,  127 south to 15, 15 west 
     to 40, 40 east to 95, 95 south to 10, 10 west to 78, 78 west to 115, 115 south to
     8, 8 east to 98, 98 west to 8, 8 west to 94, 94 west to 125, 125 south to 905,
     905 west to 5 (not doing the border-crossing U-turn!), 5 north to 75, 75
     north to 5, 5 north to 1, 1 north to 101, 101 north to 1 (Seacliff section), 1 north
     to 101, 101 north to 1 (Lompoc turnoff), 1 north to 35, 35 north to 1, 1 north to
     101 (Leggett), 101 and/or 271 and/or 254 until about Fortuna (not going to get
     too anal about this "braided" section) at 101, 101 north to 255, 255 north to 101, 101
     north to 200, 200 east to 299, 299 east to 96, 96 north and east to 5, 5 south to 97,
     97 north to 161, 161 east to 139, 139 SE to 299, and 299 back to 395 at Alturas.  Done.
     That's as close to a perimeter route as you're going to get and still stay within the state
     boundaries -- if using only state highways.  The 15-40 routing via Barstow could, of course,
     be avoided if county roads could be used from Baker south to I-40; also using Imperial
     County S34 between CA 78 and I-8 would help greatly (the same goes for A12 between
     I-5 and US 97).

And, it has to be done this in this direction, because a stretch of westbound CA 161's technically in Oregon!

[hotdogPi]

I interpreted the OP for the "remain within state" rule to be strict, but not the "state routes only" rule, which was only to prevent things from getting too complicated.

If I find myself with nothing to do one of these days, I'll try my hand at including the secondaries.

One minor exception, which is that US 275 goes south from IA 2 to Hamburg, meets IA 333, which goes to I-29 and then north on I-29 to IA 2.  The old extension of IA 333 is also closer to the border than IA 2 west of US 59.

I do believe there is not a single point where old US 75 between Council Bluffs and Sioux City is closer to the Missouri than I-29.

Technically, I made a small goof in my elaboration about a CA perimeter route:  One can use CA 265 to transition between I-5 and US 97 in Weed (saves about an aggregate mile or so!).  Carry on!

Best I could do with California's northern border, sticking to numbered routes:

starting at US 101/CA 299 junction in Arcata
CA 299 from Arcata to CA 96 at Willow Creek
CA 96 from Willow Creek to I-5 north of Yreka
I-5 to US 97 at Weed

Because of the inclusion of WA 20, the route is only traversible outside of winter.

Feels off.
I don't think Blaine can be included unless we allow old US 99 (and I'm not even entirely sure of the routing).
My take: Start at I-5 exit 256 in Bellingham.

Here's my try at Ontario (not including county or regional roads). The directions may be off (i.e. if a road went northwest, I took a guess at whether it's considered a north-south road or an east-west road).

Some technicalities, such as Highway 140 not connecting to the 406, and Hwy 3 becoming RR 3 in Fort Erie, prevented me from going into the Niagara Peninsula.

I wouldn't use the same road twice, so I would turn onto ON 17/TCH East upon reaching Nipigon and thus leaving Western Ontario out. I've struck that part out. That happened to me when I went around Aragon, Spain.

Without using ferries, the startpoint moves to Owen Sound, and from McKerrow the route would be as follow:
Continue on 17 East
69 South
529 South
69 South
400 South
12 West

Vermont is tricky because there are a number of locations, especially along the eastern border, where two parallel routes cross but don't intersect or have an interchange.  In those areas, I went with the route that spends more time along the "border".  These locations will be marked by a double-star **.

Starting in the northwest corner (in Alburgh) and going clockwise:

- VT 78$$
- VT 207
- VT 235
- VT 120
- VT 118
- VT 105$$
- VT 111
- VT 114
- VT 102
- US 2
- VT 18

- I-91 to Exit 18/Barnet**
- Barnet State Highway (unnumbered, but officially a state highway route)
- US 5 to Norwich
- River Rd in Norwich (unnumbered, but also officially a state highway route)
- VT 10B
- I-91 to Exit 12/Wilder**
- Wilder State Highway
- US 5 to I-91/Exit 11/White River Jct
- I-91 to Exit 9/Windsor**
- US 5 to I-91/Exit 4/Putney**

- VT 22A
- US 7@@ to I-89/Exit 16
- I-89 to Exit 17/US 2 West
- US 2
- VT 314
- US 2

$$:  I deliberately ignored using I-89/US 7 to Highgate and I-91/US 5 to Derby Line because of the effectively-out-and-back nature of those routes from Swanton and Derby Center respectively.

@@:  ALT US 7 is not used because it is one-way only south of downtown Burlington.  Also, there is no direct state route connection to/from VT 127 in downtown Burlington.

I was unable to map this in full because I ran out of modification points in Google Maps.

Here's my version for Texas.  I included FM roads only when they simplify the route or add a significant portion.  I started at the west end of the state, at TX 20 and Loop 375, going clockwise.

TX 20 and Loop 375
East on Loop 375

As an alternative, after going west on US 90 in Del Rio, you can go south on US 385 and drive through the Big Bend National Park and go north on TX 118 to FM 170.  They aren't state highways, so I didn't include the route in the list, but it would be a good part to add.

...
US 12 west (at times duplexing with US 20 and US 41) to I-90 east
I-90 east to US 41 south
...

The WB 12 to EB 90 maneuver is going to require either an illegal U-turn at Avenue B in Chicago or a brief stretch along city streets. I don't particularly mind entering a different state just for that, but if you want to get around this, just take 12 west to 41 south.
