Theoretical mile-based exit numbers in Vermont

[froggie]

Since Connecticut is the latest state to start implementing a change from sequential-based exit numbers to distance-based exit numbers, I sent an E-mail to the Vermont Agency of Transportation (VTrans) asking if they have a plan yet for their own implementation.  Here's the response I got:

Sort of, since it appears that we will have to.  The New England states are working on getting a reprieve from FHWA, but it's not looking promising.  The signs are the easy part.  The hard part will be coordinating with the business community, the map makers, and all the others who use the exit numbers as references for a myriad of reasons.  We haven't yet identified who within state government will take the responsibility for that coordination.

With the likelihood that VTrans will eventually have to implement distance-based numbers, I came up with my own theoretical numbers, based on mileages and standard practice elsewhere.  I also eliminated the "N/S" and "E/W" exits that exist (I-91/89 and I-89/US 2 respectively) and replaced them with "AB".  As both US 4 and US 7 have exit numbers, I have included them and VT 279, including scenarios for the rest of the Bennington bypass when/if VTrans ever completes it...the scenarios being whether US 7 gets rerouted to the bypass or if VT 279 gets the bypass and US 7 remains through downtown Bennington.

Here's the theoretical numbers by route:

Was the US 7/I-189 interchange ever numbered?  An atlas of mine from 2001 identifies it as exit 1.
