Roads that enter one county twice

[roadman65]

We have a forum already that is one county state highways.  That inspired me to have one about  a route or road that enters one county twice.

In Florida we have both FL 434 and FL 436 that enter Orange County twice with Seminole County in between. 
US 441 briefly enters Seminole County with it also being in Orange County twice.

In New Jersey, we have NJ 23 that enters both Morris and Passaic Counties twice.
I-78 enters Union County and Essex County twice.  It briefly enters Essex County where CR 577 crosses over with it being Union on both sides, and then in Newark its in Essex for five miles.

California state route 166 crosses between Santa Barbara and San Luis Obispo counties at least five times.  it's a river crossing each time, but I cannot remember which river.

on a related note, I-8 crosses between San Diego and Imperial counties at least three times, but that is due to a simple north-south county line being crossed by a winding mountain road.  (additional bonus: I believe the westbound carriageways cross two more times than the eastbound ones!)

I-49 weaves in and out of Evangeline Parish multiple times, mixing with Avoyelles and St. Landry Parishes.

[Brandon]

Illinois has several, including some interstates.  Note how often Cook and DuPage Counties are involved.

I-290: Cook -> DuPage -> Cook
I-355: Will -> Cook -> DuPage (barely and unmarked) -> Will -> DuPage
US-20: Cook - > DuPage -> Cook
US-30 (eastbound only): Kane -> Kendall -> Kane -> Kendall
IL-19: Cook -> DuPage -> Cook
IL-49 (northbound only): Vermilion -> Champaign -> Vermilion
IL-83: Cook -> DuPage -> Cook
IL-123: Sangamon -> Menard -> Sangamon
IL-267: Jersey -> Macoupin -> Jersey

I-84 enters Tolland County, CT twice, separated by a bit of Windham County.
US-6 zig-zags across the Tolland/Windham county line a couple times near Willimantic.

I-90 crosses the Hampden/Worcester county line a few times in MA.  It also crosses the Worcester/Middlesex county line and the Norfolk/Suffolk county line multiple times.

CA-41 switches between Madera and Mariposa counties several times while heading north towards Yosemite.

I-84 enters Tolland County, CT twice, separated by a bit of Windham County.

Within 15 miles on I-84, you get one little extra. Heading northeast (EAST):

Willington (Tolland County, CT)
Ashford (Windham County, CT)
Union, CT (Tolland County, CT)
Holland, MA (Hampden County, MA)
Sturbridge (Worcester County, MA)

I know I strayed from the subject a bit, so sorry about that one. Heading east along I-90 (Massachusetts Turnpike), you have this in order:

Westborough (Worcester County)
Hopkinton (Middlesex County) [Exit 11A - I-495]
Westborough (Worcester County)
Southborough (Worcester County)
Ashland (Middlesex County)
.

BOSTON (Suffolk County) [Exits 18-20]
Brookline (Norfolk County) [skims the northeast corner]
BOSTON (Suffolk County)

US 441 briefly enters Seminole County with it also being in Orange County twice.

Also in Florida: Holmes and Washington Counties in the panhandle interlock, and I-10 passes through all four extensions in turn, so you pass through, E-W, Washington-Holmes-Washington-Holmes (with "Entering _______ County" signs at each crossing, IIRC).

Any route that passes through an independent city in Virginia that has the same county on at least 2 sides. VA 144 for Chesterfield, US 301, US 58, and I-95 for Greensville, I-64 Henrico, US 60 James City, US 29/50 Fairfax, etc. US 17 also passes through the city of Chesapeake twice.

According to the map, I-64 in Virginia also passes through Louisa County twice with a section of Goochland County in between; it also passes through Goochland County twice with a section of Louisa County in between.

Google Maps isn't great for counties, so here's Bing Maps showing the area: http://binged.it/12AZhWr  It's been a few years since I've driven that stretch so I do not recall the signs confirming it. Bing Maps seems pretty good for this, though–they accurately show the way VA-231 nips a tiny corner of Louisa County just south of Gordonsville, for example.

I knew there was two counties that I-10 passed through twice, but was unsure of which two.  Thanks for pointing it out.

According to the map, I-64 in Virginia also passes through Louisa County twice with a section of Goochland County in between; it also passes through Goochland County twice with a section of Louisa County in between.

US 250 also goes through both twice, as well as Fluvanna County. Heading westbound, the sequence is Goochland-Louisa-Goochland-Fluvanna-Louisa-Fluvanna.

SR 20 here crosses from Skagit to Whatcom County, then dips back into Skagit County before crossing the mountains into Okanogan Chelan County.

[J N Winkler]

Colorado I-25 enters Weld County twice.

[hbelkins]

Plenty in Kentucky.

KY 28, for example. Owsley-Breathitt-Perry-Breathitt-Perry.

KY 2022: Perry-Owsley-Perry.

[Scott5114]

US 169 goes Tulsa-Rogers-Tulsa-Rogers north of Owasso, OK.

I-40 does something similar with Carson County, TX.

[JustDrive]

CA 62 enters and exits both San Bernardino and Riverside Counties.

[HazMatt]

I'm sure there's several more in NC, but off the top of my head.

NC 42 (Chatham)
NC 55 (Sampson)
Interstate/NC 540 counts if you consider it all 1 route.  I-540 ends at I-40 in Durham county, but continues on as NC 540 and reenters Wake county.

[WillWeaverRVA]

I-295 crosses from Chesterfield County into the City of Hopewell. Then (IIRC) it goes Hopewell-Prince George-Hopewell-Prince George-Hopewell-Prince George-Hopewell-Prince George.

[Takumi]

I think that's right. Also, VA 147 goes Chesterfield-Richmond-Henrico-Richmond and VA 197 Richmond-Henrico-Richmond.

I also know of a secondary route that does this, SR 650 for Prince George and Sussex counties, going Prince George-Sussex-Prince George.

[sandwalk]

Heading east, the Ohio Turnpike (I-80/90) leaves Wood County in northwest Ohio and enters Ottawa County for approx. 1.4 miles. Then it enters Sandusky County for about 3.2 miles.  Then the turnpike heads back into Ottawa County for another 3.2 miles....before crossing back into Sandusky County.  The road is nearly straight; the counties have a stair-step boundary.

Another couple in CT:

CT  322 goes from Wolcott (New Haven) into Southington (Hartford), Cheshire (New Haven), back into Southington

I-691 goes from Cheshire into Southington then Meriden (also New Haven).

About I-84 and Hampden County:  Only the westbound side actually enters Holland.  The sign eastbound at the state line says entering Sturbridge, which is Worcester County.

[Sanctimoniously]

Doesn't I-95 in South Carolina go something like Darlington-Florence-Darlington-Florence?

[US71]

US 71 enters Scott County, AR twice.
