How it fits

Drainage protects road foundations and reduces water-related damage.

Operations

Snowmelt, ice blockages and intense rainfall create seasonal and regional risks.

Canadian context

Authorities monitor vulnerable locations and renew undersized or deteriorated assets.

Limits and lifecycle

Extreme events can exceed normal design capacity, so resilience planning is increasingly important.

General infrastructure education only. Active road incidents, vehicle recovery and technical road work should follow responsible authorities and qualified professionals.
