Neat!

Strider:
Some of you have been wondering if I-440 will be decommissioned when I-87 routing is complete... I have been too, but then I realized that I do not think they are going to decommission I-440 because it does not make sense to end I-440 at I-87 2 miles away from I-40 interchange.

Here is the exit numbers for I-440 from I-40 to future I-87:

Exit 16- I-40
Exit 15- Poole Rd.
Exit 14- I-495/US 64/US 264 East (future I-87 North)

As you see, I-87 meets I-440 2 miles from I-40 interchange, I predict that I-440 will stay, which means I-87 will multiplex with I-440 and then both routes will end at I-40.  Similar multiplexes that end at or close to the parent route:

1. I-26/I-240 in Asheville, I-26 meets I-240 4 miles north of I-40 interchange, and runs with it until the western I-40 interchange, and I-240 ends (and begins) there while I-26 continues past the interchange.  (I-240 isn't going to be decommissioned)

2. I-73/I-840 in Greensboro. I-73 meets I-840 at Exit 3 (I-840's exit number) and both routes run down to western I-40 interchange, while I-840 ends there, I-73 continues past of the interchange.

3. I-785/I-840 in Greensboro (future), I-785 meets I-840 at Exit 14 (future exit) around 7 miles from eastern I-40 interchange and both routes run down to I-40/I-85/Bus. 85 interchange. Both routes end there.

4. I-41/I-43/I-894 in Wisconsin. I-894 ends at I-94 interchange in both termini, while I-41 and I-43 continues past the interchange.


So that is why I don't think NCDOT will decommission I-440 (it won't make any sense). They will just pair it with I-87 and have both routes end at I-40 eastern interchange.

They may do so. My major reason for arguing for a I-440 truncation has to do with the East-West direction for that route and that one has to initially head east on I-440 West when leaving I-40, and that a north direction may lessen any confusion that may cause.

I agree. I don't think NCDOT would've asked AASHTO to have I-87 follow I-440 if they didn't intend on truncating I-440. It was even mentioned in their email response to froggie that he posted in the I-36/I-89 thread.

--- Quote ---We see opportunities to reduce the length of I-440 and possibly diminish some confusion on the 440 loop.  We have not currently made this decision, but are considering the various alternatives.

I think a truncation of I-440 is all but certain.

WashuOtaku:
It would be similar to I-26/I-240 in Asheville and I-73/I-840 in Greensboro, so I doubt they would decommission a small section of I-440.  Also the fact that filthy casuals seem to understand that even digit numbers tend to loop back to the mainline.
