The Imperial Oil/ExxonMobil "test module" that's demonstrating how the biggest megaloads will fare on U.S. Highway 12 won't travel tonight after all, ITD has announced, because forecasts call for snow near Lolo Pass. Weather permitting, the giant load, now stopped just short of the pass at milepost 169.1, will start up again on Thursday night. The test load stalled for two weeks after its first night of travel, after clipping a guy wire and knocking out power to two Idaho towns.
