I wonder if the baricades are for along the train tracks to block the view of construction.
Also, I doubt the Speedway is moving its tracks, as the plan would be to close the ride. I do place money on the outer lanes being closed as construction takes place near the tracks. Sounds like the Dumbo Circus area really is going to bump up right against the speedway. Even more so than TT does now.
Could the barricades be something somewhat permanent that will block the view of Dumboland from the speedway once the FLE is complete? Not sure the speedway of the future would have a circus right in clear view. :shrug:
