The station is a normal side platform station with an entrance at the north end. It was planned in such a way as to allow an additional entrance to be built on the other side of the Décarie Autoroute, but this has not yet happened. A redevelopment plan for the area is under discussion.
The station was designed by the firm of Labelle, Marchand et Geoffroy. The station's mezzanine contains a giant suspended illuminated aluminumsculpture, entitled Système, by noted Quebec artist Pierre Granche.
Origin of the name
This station is named for rue Namur, the former name for a portion of rue Jean-Talon; the road had been renamed by the time the station was opened, so a nearby road (rue Arnoldi) was renamed Namur in 1980 to allow the station to keep its name. Namur is a city and province in Belgium.
