Usually one can bank on spring break-up being announced around March 15, give or take, but with warm weather in the forecast for southern Saskatchewan, the Ministry of Highways announced on March 1 that winter weights were coming off for highways in southern Saskatchewan.
Effective Monday at 12:01 a.m., winter weight designations for some highways in southern Saskatchewan were removed. Allowable weights will return to normal regulation weights on 52 specific roads in 101 rural municipalities, the ministry said in a release.
Winter weights typically run from about November to March. Once the road bed freezes it can withstand heavier truckloads without being damaged. This allows shippers to carry more weight during the winter months. Ministry of Highways staff carefully monitor conditions to ensure this return to regulation weight happens at the appropriate time and highways are protected from potential damage.
As an example of the warm weather expected, Estevan’s forecast highs according to Environment Canada for the week include 9 C on Wednesday, 10 C on Thursday, 13 C on Friday and 15 C on Saturday. Regina’s forecast is similar to Estevan’s, and Swift Current’s goes even higher, with a forecasted high of 19 C on Saturday.
The early onset of spring breakup will have a significant impact on Saskatchewan’s winter oil drilling season, which usually starts to shut down the second week of March. As it stands now, drilling activity for this winter is already down substantially, according to Rig Locator. On March 1 there were 24 active drilling rigs in Saskatchewan, compared to 63 on the same day in 2020 and 49 in 2019.
