Each year, during the winter season, the province allows an increase in certain axle weights on all provincial highways and an increase in maximum allowable gross vehicle weights on some designated provincial highways under the highway Winter Seasonal Weights (WSW) program.
Please note, this order reflects changes in climate zones which has been discussed/communicated earlier with the industry and internal stakeholders. The changes in climates zones from last few years include the following:
- Addition of a new climate zone in the Interlake area by splitting former Zone 1A into two zones and adjusting former Zone 2
- The above changes resulted in a total of five climate zones, instead of former four zones, to better reflect differing climatic and environmental conditions in different areas of the province
- Re-number the new zones in numerical order as 1 to 5 (instead of former 1A, 1B, 2 and 3) for ease of distinguishing each zone
Please refer to the below order and zone map for details of each zone boundary and their respective latest start date and the earliest end date (the start and end dates of the WSW vary among the climate zones depending on the prevailing weather in each zone). The WSW website update will be released soon.
MTI is monitoring the weather to determine if an earlier start date or later end date are possible for any climate zone. New order(s) will be released for an earlier start date or later end date in any zone.
