Here's what you'll see on the 511 Nova Scotia maps:

Bare (Dry/Wet)
Construction
Partly Covered (Snow/Ice)
Multiple Items
Covered (Snow/Ice)
Halifax Harbour Bridges

Road Closed

You may also see information about visibility.

Here's what descriptions may look like:

Bare (Dry/Wet)

Road surfaces can be dry or wet, but are clear of snow or ice.

Partly Covered (Snow/Ice)

Road surfaces have snow / ice-covered or snow-packed sections. For example, there may be sections where drifting snow has covered parts of the lanes or where the road centre is bare.

Covered (Snow/Ice)

Road surfaces are completely covered (snow or ice) with little to no bare sections from one end to the other.

Closed
