Interstates that do not interchange with other interstates at all.

[Mr_Northside]

Literally, no direct interchanges with other Interstates.

The US-15 / Future I-99 section does, but that is not signed as I-99 yet.

In New York, I do believe I-99 IS signed at it's interchange with I-86.

It is and it has been since around when it opened.

Until relatively recently, I-76/79 was a Breezewood. We can also argue about whether or not I-76 and I-376 interchange directly in Big Beaver, as that's technically a Breezewood, too.

As it currently stands, I *THINK* the only Interstates without a direct freeway connection to the rest of the system are I-99 PA, I-180 WY, and I-587 NY (debatable, you could count the slip ramp as a direct ramp to I-87). I-176 met this until a direct interchange was built to eliminate the Breezewood.

Separate segment from the current PA I-99. 

When they sign US-15 into PA I-99, it will have a direct interchange with I-180.

2/69C/69E is an isolated cluster.

I-587 NY (debatable, you could count the slip ramp as a direct ramp to I-87)

In that case, I-790 is in the same league.

No, I-790 has an Interstate-grade connection heading onto I-90. Heading off is a full Breezewood. That may be the one case where upgrading from super 2 to full freeway actually made the connection LESS freeway-grade.

[roadman65]

I know that I-42 when it gets built, it will not interchange with I-95.

I wouldn’t be so quick to jump the gun. There’s a feasibility study currently underway for that stretch of US-70, which includes a possible direct I-42/I-95 interhange. I seriously doubt NCDOT would want to keep a semi-Breezewood.

Where do they build.  The area is built up right to the interstate?  They would have to buy out many businesses out to accomplish that task and with that ever being done would take till at least 2030 to do.

[SteveG1988]

The Interstate 78 and Interstate 476 thing would always have been a miss for the interstate, at one time wasn't what is 22 (that goes to the turnpike) going to be 78 itself, with current day 78 being a 3di?

Don't be so quick to judge...

To add to this, I would also wager that there would be a great deal of support from Smithfield/Selma for a direct interchange since it would keep thru traffic changing interstates from mingling with local traffic and clogging up US-70, which has 5 traffic lights between both ends of the current US-70 Bypass. I've been through there numerous times when I lived in Goldsboro and it can get really congested there, especially with trucks. I'd love to see the interchange built.

I-587 has a ramp bypassing the roundabout to the Thruway, so it's the same situation: freeway connection heading to its parent, not a freeway connection heading from the parent to the child.  Unless you're actually arguing on the basis that the roundabout is easier to handle than making three right turns in quick succession.

They probably will close the US 70 interchange just north of this.

[froggie]

^ I doubt that.  Because you will have then eliminated access from the main travelshed that most of the businesses at that interchange rely upon.

[roadman65]

I am not saying not to build it, but with the US 70 interchange being just north of it you are going to need braided ramps which takes up right of ways and with the buy out of land from developers, even with eminent domain still takes years to process.

US 70 has many businesses that rely on the interchange unlike old US 74 where NCDOT was able to close it due to lack of many businesses at the former location.  Flat out, Selma is a hugely developed area and along with Smithfield it holds a lot of population as well.

No...what you were saying is that "so much right of way would be needed" that it would either take forever to build or would be built without a direct connection.  And then I showed you a theoretical design that would build a direct connection and *NOT* take so much right-of-way, thus preserving most of the businesses.  Conveniently, you ignored that...

[OCGuy81]

How about I-69 in Kentucky? Doesn't it only intersect with Kentucky's parkways?

[froggie]

^ No.  It intersects and has a concurrency with I-24.
