Getting from Indiana to the rest of at least the lower 48...

[Konza]

Routes that pass into or through Indiana:

Interstates:  64, 65, 69, 70, 74, 80, 90, 94.

US routes:  6, 12, 20, 24, 27, 30, 31, 33, 35, 36, 40, 41, 50, 52, 131, 136, 150, 224, 231, 421.

Counting the Indiana counties these routes pass through, I get 1107 total counties reached by these routes.  That's less than Illinois or Texas- but given the number of counties served by US routes in Texas, the routes that pass through Indiana reach more counties outside the state than the routes that pass through Texas do.

Indiana's wearing the bronze in the clubhouse.  Anyone want to kick them off the podium?

I-69 shouldn't count, because it's not a continuous route south of US 41 at Evansville. Yes, you can take US 41 and then the Purchase Parkway and US 51 to get to the signed portion in Mississippi, but the entire route is not marked as I-69.

[Konza]

I erred on the side of generosity with I-69 but there was not way I was going to give any credit for it west of the Mississippi River.

Ditto with split routes; I included the counties for both US 31E and 31W, and for some alternates like US 27 in Florida and US 41 in Kentucky and Tennessee.

Indiana is hurt by not having any NE/SW diagonal routes.

And should the former routes of US-27 north of Ft. Wayne count? As US-27 was removed from Michigan in 2000 and north of the current US-127/75 split in Grayling in 1962.

US 460 as well.  Truncated at Frankfort, Kentucky because it had been supplanted by I-64 from there west through Louisville and Evansville to St. Louis.  East of Frankfort, though, the routes diverge from each other, although they both end in or near Norfolk, Virginia.

It opens up a can of worms, though.  For example, would you include US 21 and US 25 if you were doing this for Ohio?  US 25 was replaced by I-75 north of the Ohio River, but diverges from it south of there.  US 21 extends farther south than I-77 does.

And what about US 66?  It took five Interstate highways to replace it.  US 66 cuts off the southeast corner of Kansas, but none of the Interstates does.  How many additional counties would you be able to reach from Kansas had US 66 not been decommissioned?

US-131 doesn't enter Missaukee County in Michigan

[Konza]

I've updated the map and made some corrections.

I've added the counties traversed by the decommissioned US 27 in Michigan and the decommissioned US 460 east of Frankfort, Kentucky.

The count is now 1143.

They didn't nickname us the "Crossroads of America" on a whim!

[webny99]

No Texas is unfortunate, though.

EDIT: I just noticed you've got Wyoming County, NY marked.
But US 20 doesn't hit Wyoming County. Only US 20A has that distinction. 

[Konza]

Again, I've included counties entered by alternates of the routes I've plotted.

If you were to do this for Oklahoma, Kansas, Missouri, or Iowa, how would you treat I-35E and I-35W?

I-35E and I-35W are mainline, as are US 31E and US 31W. US 20A is not mainline.

The count is now 1143.

I guess if you are going to use the decommissioned routes, you should add US 641. It ran into Evansville until sometime in the early 70's.  Probably when US 41 was relocated.

[Konza]

I've elected to use decommissioned routes if they were decommissioned due to being replaced by an Interstate.  US 460 qualifies as it was essentially replaced west of Louisville by I-64.  Routes like the one you mention don't fall into that category.

[US 89]

I've elected to use decommissioned routes if they were decommissioned due to being replaced by an Interstate.

In that case, you may want to include the old US 30S in Idaho/Utah/Wyoming, which was decommissioned after being replaced by I-80N (now 84). That would add Box Elder, Weber, Morgan, and Davis County in Utah to the list.

Why is US 62 on here? It doesn't go through Indiana.

[NWI_Irish96]

It's not.

US 62 is in the county map posted above.

That appears to be the relevant map for Ohio, not Indiana.

[Konza]

It's been Pennsylvania and Ohio since it was Indiana, and is about to be changed again.

County counts should stilll be in the ballpark, and will be updated.

This looks like the map for Tennessee, not Indiana

[Verlanka]

It's a live image.

[StogieGuy7]

Why doesn't the image seem to include the I-80 and I-90 (Toll Road) corridors?  Looks like that corridor is blank, yet that's the #1 through route that includes Indiana. Your map looks like connections through Indianapolis, rather than Indiana as a whole.

It's a dynamic image. Right now, it's showing Tennessee.
