Drivers are being told to expect delays and plan an alternate route Monday and Tuesday, as heavy machines are moved. It'll make quite a sight on the highway - two huge evaporator units will be shipped from a Babcock and Wilcox plant in Melville, Sask., this week.a The big move on Monday and Tuesday will slow traffic on Highway 15 between Melville and the junction with Highway 2, then along Highway 2 from the junction with Highway 15 to Highway 11, and finally down Highway 11 to the K+S mine access road and to the site that is currently being developed.
