Roads, Winter & Structures
Pavement, winter maintenance, drainage, bridges and remote corridors.
Canadian road infrastructure: who does what
Canada’s road network is a layered system of municipal streets, provincial and territorial highways, structures, maintenance systems and national trade corridors.
How winter road maintenance works in Canada
Winter operations combine weather information, plowing, traction management, equipment staging and traveller information.
Road weather information systems in Canada
Road weather systems combine environmental sensors, communications and operations centres.
Why Canadian pavement design has to account for climate
Canadian pavements experience wide temperature ranges, moisture, freeze-thaw cycles and heavy loads.
Road drainage, snowmelt and flood resilience
Culverts, ditches, storm systems and bridge openings help move water away from transportation corridors.
Bridges and road structures in Canada
Bridges, overpasses, retaining structures and large culverts are managed as long-life assets with distinct inspection and repair needs.
Road infrastructure in northern and remote Canada
Remote transportation systems face long distances, severe weather, limited alternate routes and difficult maintenance logistics.
How infrastructure supports road safety
Road design, markings, signs, barriers, lighting, drainage, maintenance and vehicle systems all influence safety.
