Counties reachable with a single route from your metro area

[SkyPesos]

I was lurking on some of the "Counties reachable with a single route from a state" threads today, starting with Illinois, and thought it would be interesting to do this with metro areas too. This time, state routes are included. You can either list the counties below or make a map of them and post it below. Here's a map for the Cincinnati metro area:


Counties colored: 434 (not including Cincinnati MSA), 450 (including Cincinnati MSA)

The Oklahoma City one is kind of insane.

I wouldn't be close to having the time to do this for Chicago, but I would think we could all agree it would have the most.

Toledo most likely wouldn't beat Chicago, though with I-80, I-90, I-75, US 6, US 20, US 23, US 24, it could probably be somewhere on the top.

Remember the Chicago MSA includes 4 counties in Indiana and 1 in Wisconsin, so you get interstates 41, 55, 57, 65, 80, 90, 94; US Highways 6, 12, 14, 20, 24, 30, 34, 41, 45, 52, 231, and several state highways in all three states.

Yea I know.

On the opposite end of the spectrum, you have some of us who don't live in a metropolitan (or even micropolitan) area.  Using my home county, I think I would net a total of 13 other counties.

Anyone notice that the map background is missing I-22? (So is the New York Times default background map, for that matter...)

EDIT: @admins: Does a several thousand × several thousand non-SVG image (which is what you get after clicking) strain the servers? These maps are perfect for being SVGs, but somehow they're not.

Indianapolis MSA is 11 counties so there are a lot more SR and even a couple more US.

This map is a bit outdated, as it is also missing I-2, I-11, I-41, and more.

I think the highways overlay may be from like 2010, as it's missing some more noticeable new additions in the last decade, like I-69 south of Indy and I-49 in MO.

Fun fact: There are at least 6 MSAs only crossed by state routes, thus they are unable to reach any counties outside their states. Five of them are in California: Chico, Madera, Modesto, Santa Cruz-Watsonville and Visalia. All but Santa Cruz used to have a US Route (US 99). The other is Ithaca, New York.

Another interesting fact: Starting from Barnstable Town, Massachusetts MSA, only three counties can be reached on a route other than US 6. So its map is a pretty lopsided one, with a few counties in Eastern Massachusetts and a long string going almost all the way to the other end of the country, courtesy of the longest US Route ever, but (according to some metrics) not currently.

[hotdogPi]

Another interesting fact: Starting from Barnstable Town, Massachusetts MSA, Suffolk county (the one with Boston in) is the only one directly reachable on a route other than US 6. Its map is basically the counties traversed by US 6 plus that one.

MA 28 reaches Middlesex County and Essex County.

[CNGL-Leudimin]

You are correct. For some reason I thought MA 28 stopped in Boston.

For the Tri-Cities in Michigan (Saginaw, Midland, Bay City)
These are the number of counties each route goes through not including Bay, Midland or Saginaw County.
I-75: 81
US-10: 30
US-23: 65
M-13: 3
M-15: 3
M-20: 4
M-25: 4
M-30: 2
M-46: 6
M-47: 0
M-52: 5 (3 more with connecting route OH-109 at the Ohio border)
M-81: 2
M-84: 0

I live in the Greeley MSA, but for the purposes of this thread, I'll use the Denver combined statistical area.

Here's one for a metro I used to live in: St Louis


Counties colored: 417 (not including St Louis MSA), 432 (including St Louis MSA), 479 (including counties formerly reached by on US routes)

EDIT: Fixed US 61 at northern end, and Added counties on former US 40 and 50 routings in the west in.

I just did a count for Toledo, and not including Ohio state routes, you can get to 491 counties (including the 3 counties part of Toledo MSA), with the 7 routes I mentioned above, as well as US 223. Pretty impressive for its size and population!

Since my metro area is basically synonymous with Waterloo Region (which I already did here), I'll do the GTA (Toronto, ON) instead:


Black = The GTA
Yellow = The 401 and Quebec A-20
Purple = The 400
Brown = The QEW
Dark Blue = The 403
Lighter Blue = Highway 9 (note: this ignores a downloaded gap between Orangeville and Harriston)
Red = Highway 7
Green = Highway 10
Orange = Highway 35

Here's one for a metro I used to live in: St Louis


Counties colored: 422 (not including St Louis MSA), 437 (including St Louis MSA), 463 (including those on former US 66)

You used US 61's historic extent and US 66, but forgot to add the historic US 40/50 counties on their former western extents.

I forgot that US 61 doesn't reach the Canadian border since decades ago, and it's now MN 61. Oops. Fixed that, and added in counties on the former US 40/50 routings.
