Title: Highways from a County into another state with the same name
Post by: roadman65 on March 31, 2025, 06:52:00 PM
I-95 leaves Delaware County, PA for the State of Delaware.

Then I-70 leaves the County of Ohio in West Virginia for the State of Ohio.

In the latter it crosses a river with the same name separating the two different entities, but in the former both named entities aren't separated by namesake River, but directly on it.

I-80 passes through Nevada County, CA and the state of Nevada.

Not directly, though, it goes through a short segment of Sierra County between them.  (Nevada County does abut Nevada, but I don't believe any roads cross that boundary.)

The only county in Indiana sharing a name with a bordering state is Ohio County, but there are no bridges over the Ohio River from that county into Ohio.

Oklahoma has a Texas County, from which US 54 and OK 136 enter Texas.

Colorado only has Washington County, and, alas, none of I-76, US34, or US36 make it to Washington.

Turning the calendar back over a century, the Yellowstone Trail (early auto trail) went through Washington County, WI and ended in Seattle.

MN has US 12 in Washington County (though only signed one time), which goes to Washington state.

I-5 and I-205 both travel from Washington County, OR to Washington.

Ironically, Mississippi County Arkansas does NOT abut Mississippi, but instead Tennessee. 

It is on the Mississippi River well north of Memphis which itself is north of Mississippi.

I thought Kentucky was on the other side of the river from Ohio County.

A near miss, but US30 goes through Washington County, Nebraska and runs right along the Columbia next to Washington without actually entering.

Dakota County, Minnesota has US52 which enters North Dakota.

You must mean Washington County, Oregon but US-30 doesn't go through the county or enter Washington State at all. Washington County, Nebraska is a long ways from Washington.

No, I mean Washington County, Nebraska, which has US30 enter it. And then US30 just barely misses Washington.

Considering my home state doesn't have a Wisconsin, Indiana or Ohio county, Michigan is out.

How about on the Kentucky side?  Ohio County does not border the state of Ohio, nor does it border along the Ohio  River anymore.  But US-62 rambles through 10 other counties in Kentucky on its way to cross the Ohio River in to Ohio.

Both I-55 and US 61 travel through Mississippi County, Arkansas, and a majority of the length of both routes are located in Mississippi.

Illinois has three more miles of I-55 than Mississippi does. (Neither state has a majority of the route, but Illinois has a plurality of it.)

As do US 13, US 202, DE/PA 261, and DE/PA 491.  DE/PA 100 used to, and I-495 comes oh, so close.

Ohio County, Kentucky is quite aways away from Ohio though. It used to border the river so it's kind of a mystery why either Hancock or Daviess County didn't hold onto the Ohio County name and the current county renamed. Anyway everything named Ohio is named after the river, the state and counties in Indiana, Kentucky and West Virginia. I was assuming that the way this post was that the county borders the state with the same name and the highway goes through both the county and state in question.
