PORTLAND, Ore. (AP) — A 450-ton shipment of oilfield equipment that's been rumbling toward Idaho for days should enter the state sometime tonight or tomorrow morning. The "megaload," bound for the Canadian tar sands oil development, has been delayed by protests and bad weather in Eastern Oregon.

It got permission from officials there for a daylight run Tuesday, traveling 50 miles on a stretch at elevations above 4,000 feet where the state said ice was feared after dark. A spokeswoman for the moving company, Holly Zander, said the transport could reach Vale today.

That's just over the border from Idaho, where the Transportation Department plans to issue a permit. On Monday, 16 people were arrested near John Day. Environmentalists tried to block the rig, contending tar-sands development will contribute to global warming.
