The station, planned under the name "Aqueduc",[5] was designed by the firm of David, Boulva & Cleve.

A sculptural grille by Jean-Jacques Besner covering a ventilation shaft is the only artwork.

The station is a normal side platform station, with a mezzanine on its eastern end, which is connected to the exit by an extremely deep open shaft.

That train station was built as part of the Bell Centre and replaced the former Gare Windsor.

This station is named for Lucien L'Allier Street, whose name was changed from rue de l'Aqueduc in order to commemorate Lucien L'Allier, chief engineer for the initial network of the Metro, as well as for the construction of Saint Helen's Island and Notre Dame Island for Expo 67.
