Mega-projects added to the size throughout the 1990s, including Le 1000 De La Gauchetière (the tallest building in Montreal), Le 1250 René-Lévesque, and the Montreal World Trade Centre. Although these buildings have only a secondary commercial sector, they use their connection to the underground city as a selling point for their office space. Also, the construction of a tunnel between Eaton Centre and Place Ville-Marie consolidated the two central halves of the underground city. The construction of the Bell (originally Molson) Centre connected Lucien-L'Allier Metro station to the underground city, as well as replacing Windsor Station with the new Gare Lucien-L'Allier commuter train station.
