I don't believe the tunnel and tracks are completed yet near the new Tron attraction so those steps will need to finish first.
To see what may be closed on your dates, go to the
MDE app and click the 'hamburger' (3 lines) in the bottom right of the screen.
From there select, 'Park Hours and Info'.
If hours have been announced for your date(s), click those and it will list what is scheduled to be closed for refurbishment on those dates. Unfortunately if park hours have not been announced for your dates then this method will not work.
