[Talk-us] Announcing progress: Minnesota Highway classification project publishes first guidance

[Bob Gambrel]

I really want to be clear about your position so I do not misstate it in
the channel. I know you have already covered it but if I try to piece it
together from the thread I might get it wrong. Am stating what I think your
position is. Let me know if I got it right ...

1) Barring exceptional edge cases ...
2) A motorway should not end/start at an at grade intersection
3) A motorway should start/end  where a ramp touches the carriageway

I cannot remember in the long thread whether you weighed in about the
length of a motorway island. Following are questions about that. The slack
discussion that Evin initiated is more about item (a) below and I want to
make sure your thoughts enter that discussion ...

a) Do you believe there is a minimum number of (non at-grade) interchanges
there should be before we classify something as a motorway? For example, is
a one interchange motorway island ok?
b) Do you have any particular concerns about the minimum length of a
motorway island?

I hope you don't think I am being picky here. I really want to get your
thoughts into the discussion, if you don't join it yourself.

To recap the current guidlines in Minn: motorways islands have no minimum
length requirement, can consist of as few as a single interchange, and end
at the first at-grade intersection.
