I-781 requested in New York

[froggie]

New York has requested that the under-construction connector between I-81 and the Fort Drum main gate be designated as I-781.  They already have preliminary approval from FHWA.  This is the request to AASHTO.

I saw the plans on the web and I'm surprised the interchange with I-81 is a trumpet not flyovers...I thought trumpet were frowned upon nowadays.

If the designation actually extends to Fort Drum (rather than just to US 11), I see difficulties in clinching it.

[FLRoads]

Perhaps the interstate designation will end at U.S. 11 with the state route continuing into Fort Drum, or not be signed at all. Either way its nice to see a new interstate number on the books

Is that even legally allowed, to have an interstate with such access restrictions?

H-3 in Hawaii ends at the gates of the Marine base.  I clinched it with an "I'm sorry, sir, I seem to be lost.  Can you please direct me to Honolulu?"

[Alps]

I've clinched a few routes (especially in MD) just by U-turning at the gates.  The only route I know of that extends into the establishment itself is NJ 68 and Fort Dix.

From the report:

It is proposed that Interstate 781 would end at the Fort Drum boundary at the location of the North Gate (main
gate).

So, yup, another U-turner.

Most of the traffic is expected to be to/from the south, hence why the trumpet was considered acceptable.

Is that even legally allowed, to have an interstate with such access restrictions?

Yes it's allowed.  Consider, in part, that Defense was an integral part of the Interstate's creation.

Also, I-564 in VA.

The rest of the topic has been moved to General Highway Talk under the heading "Restricted Highways".

Figured this has migrated away from the scope of just future Interstate 781 and deserved its own thread.

I really don't know why NY 781 (which it was designated originally) should be an interstate. If it was interstate for a short point, and an NY state touring route for the rest (to the gate), maybe it would make more sense.

[froggie]

Why not?  After all, it's the National System of Interstate and Defense Highways, and 781 directly connects the main gate at Fort Drum (which has seen a lot of expansion in recent years) to a major Interstate.

Makes perfect sense to me...

[agentsteel53]

it certainly beats having some commuter lemming path being upgraded to yet another generic three-digit interstate!

Isn't there a requirement to terminate at other NHS routes?

[froggie]

Not outright.  Again, this is a major military base.  Thus, quite allowed and makes a lot of sense.

'Sides, US 11 through there is on the NHS...

[vdeane]

It won't be ending at US 11; it's planned to end at the main gate to Fort Drum, last I heard.

[Roadgeek Adam]

Yes it is and will be. I don't agree with the interstate designation, but I won't win that fight.

[njroadhorse]

Hey, if I-564 can be signed as such, I suppose I-781 can too.  After all, they both serve major defensive areas for this country.  I believe I-564 is also signed to the main gate of Norfolk Naval Station too, no?

[froggie]

No.  Ties into the at-grade part of Taussig Blvd (outside the base boundary) just west of the Gate 3/3A interchange, and officially becomes VA 337 at that point.
