Highways 1 - 99 when not at Freeway standards. These highways connect major areas of the province.
Highways 100 - 399, and 900 - 999. These highways connect cities and towns to other highways.
Highways 600 - 799. These are grid roads (6xx run North/South, 7xx run East/West). While not as sturdy as other Highways, these roads will stand up to truck traffic and should be preferred over other rural roads.
Other Rural Roads
Other Rural roads should be entered as unpaved Streets, as these should only be used for routing if no other option is easily available.
