Slightly off-topic, but are there any interstate "triangles", where three interstates connect with no intermediate exits on any of the three sides?
Closest I can find is I-65/I-465/I-865 in Indiana. 2/3 of the sides have no exits, but I-465 does have 2 exits.

Colorado almost has one. Southbound on I-25 has Exit 217B (I-270) followed by Exit 216 (I-76 Westbound), but with Exit 217A sandwiched in between for US36 Westbound.

The Denver one comes even closer, doesn't it?
Keep right except to pass.  Yes.  You.

Denver might qualify, depending on if CO 224 counts as a separate exit or not.

Right in that area, though, you have I-76 hitting I-25 and I-270 as well as I-270 hitting I-76 and I-25.

Truth. Was only thinking about one side of the triangle.

In theory, US36 is an extension of I-270 (which is also US36), so it's basically the next exit, just with the opposite direction of the highway ruining it.

You get close at I-95/295/695 in New York, looks like there's 1 exit on 695, 1 exit on 295, and nothing on 95

Cheyenne, doesn't it go from I-25 to I-180? I can't recall if there's another exit between those, or just more cows.

In Lansing, MI: I-96 has consecutive exits for I-496 and I-69
The Saginaw exit (M-43) is in between.

Other side. Exits 95 and 97.

Also, the Indiana Toll Road goes from I-65 to I-80/94
Davenport, IA -> Valparaiso, IN -> Ames, IA -> Orlando, FL -> Gainesville, FL -> Evansville, IN

Just more cows. And wind. No exits.

But is WY I-180 really an Interstate???  :confused:

In Houston, Interstate 69 south kind of does this. Exit 132 is for IH-10 and while there is an exit for Jackson Street to downtown, if I remember correctly, the ramp for that is actually part of the same general interchange with the ramps for IH-10. The next exit after that is for IH 45.

I-10 Westbound in Louisiana has I-310 then a ten mile gap before the next exit to I-55.

Another near triangle: I-495, I-270, I-270 Spur in the DC area with one exit on 2 of the sides.

What about the triangle of I-88/I-290/I-294 in Chicagoland?

There is the York Rd Exit from the I-88E->I-294S ramp, the entrance from York/Harger Rds to I-88W and the Cermak and Roosevelt exits on 294

ET21

A couple IL ones,

I-294 SB has I-90 E/W followed by I-190 West
I-294 SB also has I-290 West first, followed by I-290 East and I-88 West. The order may change due to the ongoing roadwork

And as mentioned above, I-88 EB has I-294/York Rd first followed by I-294 North/I-290 West with the mainline heading into I-290 East
The local weatherman, trust me I can be 99.9% right!
