Most recently, in 2003, the complete redevelopment of the Quartier international de Montréal consolidated several segments of the central underground city with continuous pedestrian corridors. The construction of the ICAO headquarters joined Place Bonaventure to Square-Victoria-OACI station, which in turn was joined to the Palais des Congrès and Place-d'Armes station via the new Caisse de dépôt et de placement building and a tunnel under Place Jean-Paul Riopelle. Uniquely, the new tunnel sections in the Quartier International contain educational and artistic displays sponsored by major Montreal museums. As a result of this construction, one can now walk all the way across the centre of downtown, from the UQAM Sherbrooke Pavilion at the corner of Sainte Famille Street and Sherbrooke Street to the Lucien-L'Allier Metro station just south-west of the Bell Centre, without going outside — a span of as the crow flies, or approximately walking distance.
