I'd say the way it is will work fine. Personally, I'd put a slash. Or if the vote for the "sketch-ramp" turns out to be "yes", use a colon to separate the shield name from the control city.

Yes, in fact the four left lanes come from I-695, not I-395, so all those who come from and continue on I-395 must shift lanes to the left.

I don't know.

It's a judgment call you're not going to be able to make just by looking at a map. You have to be driving, and realize you're faced with an urgent decision and Waze hasn't said anything. Then you look at the screen and see that you're in the wrong lane, but at that point, it's too late.

Would a short ramp segment work better?

5 lanes before the split, only the left 3 stay on the interstate. I would vote yes.

If you were in the right 2 lanes you would need to get over to stay on the interstate...

Here are some examples of my latest "standard" I've used for complex freeway to freeway junctions:

I-40 / I-640 outside of Knoxville (to the East)

I-40 / I-81

I-40 / I-75 split west of Knoxville

If it is possible to be in a travel lane for a few miles and that travel lane only goes to one branch of the split, I assume that reassurance directions are needed. The first and third examples I provided did generate user requests that directions were needed in the client at these points. The second didn't have any URs in Waze, but every time I drive there cars are jumping left and right like crazy trying to get in the correct lane.

To facilitate the directions, I used short ramp segments. These make the fact that a decision is to be made very obvious. I made the ramp as long as there is pavement between the two branches. This keeps the client zoomed in long enough for you to see the detail of the junction, but then zooms out so you can see your next turn if you are going "straight". If you use only freeway segments, the client never zooms in at the split to show you detail. In some cases it is very helpful to have that visual clue.

Let me know if anyone has any questions about what I did. I either have a good explanation or I just screwed up

Yes, good example of the one time we want to leave road segments un-named. Many editors have used this, but it is hard to explain to new editors some times. They just see a road with no name and think it must be missing.
