BackgroundWinter Readiness
“Winter-ready” cycling infrastructure has adaptations that facilitate winter maintenance

Winter Maintenance Basics
Winter Maintenance Basics Basic Basic Operations
● Salting: spreading of melters to prevent ice formation and snow compaction
● Gritting: spreading of abrasives over packed snow to prevent loss of traction
● Snow clearing: transfer of snow from cycle lane to temporary on-street storage
● Snow removal: disposal of excess snow
Winter Maintenance Basics Snow Clearing
Snow clearing is usually combined with salting or gritting
Triggered by snow accumulation on the cycle lane
Performed frequently over the course of the winter
plow and rock salt

sweeper and brine
Winter Maintenance Basics Snow Removal
Snow removal is a slow and complex operation
Triggered when on-street snow storage capacity is reached or exceeded
Performed infrequently
Very expensive
Design Considerations
Design Considerations Equipment Dimensions
Does available maintenance equipment fit?
Will new equipment need to be acquired?
Design Considerations Equipment Dimensions
Design Considerations Detectability
Is the cycling infrastructure easy to locate under snow cover?
Design Considerations Detectability
Design Considerations Snow Storage
from road from cycle track
Design Considerations Snow Storage
Can snow be easily transferred from the facility to storage sites?
Is the capacity of storage sites sufficient?
Design Considerations Snow Storage
Design Considerations Snow Storage
Stored snow that encroaches excessively into the cycle track must be removed
more storage = less frequent removal
Design Considerations Snow Storage
Design Considerations Drainage
Where does meltwater from stored snow drain?
Meltwater that runs over the cycling lane can cause icing

Design Considerations Drainage
Where does meltwater from stored snow drain?
Snow should be stored downslope from the cycle lane

Design Considerations Snow Removal
What can impede the removal of excess snow?
Delineator posts along temporary cycling facilities slow the transfer of snow to the roadway.
Design Considerations Snow Removal
What can impede the removal of excess snow?
Vegetation and furniture can be an obstacle to snow removal

Design Considerations Consolidation
Can the number of passes required for snow clearing and salting/gritting be reduced?
Simultaneous maintenance of sidewalk and cycle track
Design Considerations Consolidation
Can the number of passes required for snow clearing and salting/gritting be reduced?
Simultaneous maintenance of both directions in a bidirectional cycle track
