Interstate Highway Question

[The Nature Boy]

Why hasn't I-585 been decommissioned yet? It really serves no actual purpose at this point.

Because SCDOT wants to extend it to I-85.

Another question: was/is there a section of Interstate that doesn't connect to any other? As far as I know, no. This does not include highways that will be as they are constructed. Asking for a friend. 

Very recently, I want to say one of the I-69 suffixed routes in South Texas was on its own, so to speak, before I-2 became signed (69C, maybe? Not sure about the chronology of everything down there). Even now, the system of I-2, I-69C, and I-69E is disconnected from the rest, but that's only temporary, and it doesn't really answer your question.

Which one doesn't connect to any others? None of them, that's which one.

Decommission it until they actually do that. Let SC call it SC Highway 585 if they want to.

I-585 is fully signed in both directions along US 176 from west of I-85 Bus to just short of I-85 (1 at grade intersection adjacent to I-85), including on the ramps from both directions on I-85.

There are also mile markers 1-3 where mile 0 would be at I-85.

On the other end, the I-585 posting on Pine St leaving US 29 now says TO I-585 instead of NORTH I-585, but there is still at least one 585 NORTH posting on Pine St well before the actual freeway begins at the US 221 interchange.

If I-85 Bus were I-685 this would not be an issue and if SCDOT wanted to connect 585 out to 85 they should've had a different interchange design with US 176 which is a simple diamond in a small geographic footprint.

I-170 in Baltimore never connected to another Interstate, and has since been removed from the system.

I-70 ends at I-695.
