Montreal’s hidden rivers resurface as recent floods disrupt highways
Montreal’s recent record rainfall exposed the locations of buried rivers, leading to severe flooding on city roads and neighborhoods, particularly on Highway 40.
In short:
- Montreal received up to 158 millimeters of rain in 24 hours, causing widespread flooding.
- Old maps reveal that rivers now confined underground contributed to the flooding of Highway 40.
- Urban planners suggest that better infrastructure and green solutions could mitigate future flooding.
Key quote:
“Our topography recalls the presence of these waterways.”
— Pascale Rouillé, urban planner and the founder of Les Ateliers Ublo
Why this matters:
As climate change leads to heavier rains, Montreal’s outdated infrastructure struggles to manage water, raising the risk of more frequent and severe flooding in the future.
