Other cities have tried to construct
networks sheltering pedestrians from inclement weather,
but the Montreal system, the world's longest and best-known,
with its kilometres of corridors and shopping promenades,
has clearly managed to pull together all the right conditions
to enjoy great popular success.
The underground city is still growing
today. In recent years, a link has been added between
Place Ville-Marie and shopping centres farther north,
themselves linked to another metro line. Another recent
connection gives access to the southeast, to the Stock
Exchange tower and a new urban complex, and even to
a gateway to the historic city centre, where pedestrians
can stroll along the narrow streets, outdoors.
