So to finish this question of the elevators and the tram path.
So we have two sets of elevators, one closest to the current tram path and one closest to Magic Way.
From the information from DLR>WDW we know that the elevator closest to Magic Way will bring guests to the 2nd floor for bridge access.
And now based on this image from today's Fresh Baked video we can see that the elevator closest to the current tram path opens out to the "courtyard" area. Red is the tram path going under the escalator hub, and yellow is the elevators, showing opening out.
So there you have it, the tram will be going underneath the escalator hub and no guests will be crossing its path. Also its interesting to note that there are 3 elevator bays, not 2. So there will be plenty of elevators for the new parking structure.
I hope that answers all your questions on the tram path and elevators
