La. Civ. Code art. 752
Current with operative changes from the 2024 Third Special Legislative Session
If the exercise of the servitude becomes impossible because the things necessary for its exercise have undergone such a change that the servitude can no longer be used, the servitude is not extinguished; it resumes its effect when things are reestablished so that they may again be used, unless prescription has accrued.
