If you mean World Drive then nope
If you're talking about the entrance though, that's likely being re-routed, but they aren't expanding the park boundaries over there. It's more for the parking situation.
Also, it should be pointed out that awhile ago a permit was filed for a construction entrance to be built off World Drive to where LMA currently is. LMA deconstruction cannot truly start en mass though until they finally move Uncle Walt's plane. It's wayyyyy too close.
