The Belgian parliament's commission of inquiry into the attacks is due Friday to visit both Maalbeek station, near the EU's headquarters, and Brussels Airport as part of its mission to shed light on both attacks by the end of the year.
Maelbeek station has been closed since Khalid El-Bakraoui detonated a bomb at 9:11 am on March 22 that killed 16 people on a train, part of coordinated attacks that hit the airport in Zaventem neighbourhood just over an hour earlier.
Reconstruction work will be completed Friday evening, Ledune added.
One of the station's eight tiled portraits by artist Benoit van Innis remains damaged and will be covered up. The same artist is now working on a project to commemorate the massacre that is due to be completed in June, Ledune said.

"In the meantime, we plan to set aside a remembrance wall where people can leave messages, words of hope," she added.
Brussels airport is set to resume full operations in June after it was completely closed to passengers for 12 days following the attack and then began gradually to restore service.
The airport bombings were carried out by Khalid's brother Ibrahim El Bakraoui and Najim Laachraoui -- the alleged bombmaker for the November 13 Paris attacks.
Police earlier this month arrested Mohamed Abrini, who confessed to being the "man in the hat" caught on video with the two airport bombers and who allegedly was preparing to detonate a third bomb before fleeing the scene.
He was filmed on CCTV talking to Khalid El Bakraoui minutes before the bomb went off.
