As I was laying in bed last night, it dawned on me what the issue was. Back when the layout was in the garage and I was ballasting the track, I didn't have issues with the ballast floating up, at least not like the problem yesterday. But because of the confinement of the bridge, the alcohol wet water and the glue mixture had no place to run out. All it could do was build up above the ballast until the alcohol and water evaporated out of the glue.
One weird thing I noticed yesterday was that as I put the glue on the track, there was an "upward flow" of alcohol and ballast at the outside confinements of the bridge. What I am thinking - again because of the confinement of the bridge - the heavier glue mixture was pushing down on the alcohol and the alcohol was flowing up at the edges of the bridge, lifting the ballast.
So at least I feel better now - I'm certain that the rest of the ballasting on the non-bridge track will go well.
