Repair work to restore the eternal flame at the gravesite of former President John F. Kennedy has been completed at Arlington National Cemetery.

On Oct. 29, the cemetery transferred the flame from a temporary burner to the restored permanent eternal flame that is part of a memorial to Kennedy.

Repair work started back in April to replace components of the eternal flame's burner, according to the Associated Press. Contractors were hired to install new a new burner assembly, drainage lines below the flame, and gas and air lines.

The restored eternal flame was supposed to be finished by late May, but the flame remained on a temporary burner until this week.

The temporary flame was decided on so tourists could see something while the repair work was being completed.

Officials at the cemetery said the new equipment will make maintenance a lot easier, according to the Associated Press. They also said the repair work was probably a little overdue after four decades of use.

The 50th anniversary of Kennedy's death will take place on Nov. 22.
