Since this group is interested in the building details, lets talk about the ramps on both sides of the actual bridge. As stated, the bridge height is going to be about 20 feet, but that more than likely includes a fence. You need 16 feet of true clearance underneath it for the roadway. And lets say 4 feet is the actual structure, and the fence places it over the 20 foot comment.
ADA laws says a 1 in 12 grade is the max allowed, so for every 12 feet, you can only raise the height one foot, and there is also a requirement for a flat "rest" area every 30 feet (think the Monorail ramp and how it zigzags in Tomorrowland). (And there some other options with lesser slope designs)
So we are looking at about a 900 foot ramp needed on each end of the bridge.
So take that into consideration, and this is without needing an elevator.
If you look at the Las Vegas version, they opted for elevators and escalators for access to shorten the space needed to build them. But this has major impact on volume, especially a breakdown. Look at the Mickey and Friends Structure and the back ups at the elevators there for example.
