CANYON CITY, Ore. (AP) — More than a dozen megaload protesters are in the Grant County Jail Tuesday in Canyon City in northeast Oregon. A woman who works at the jail says they were arrested overnight for disorderly conduct. The group Rising Tide says 16 people were arrested for blocking a huge shipment of oil refinery equipment on Highway 26 outside John Day. The group says they locked themselves to two disabled vehicles in the path of the megaload. The incident comes as Idaho officials gear up for additional planned megaload shipments through North Idaho in the coming weeks; a public meeting on possible brief closures of I-90 through Coeur d’Alene to accommodate the loads has been set for Thursday. The crews moving the 450-ton shipment in Oregon had hoped to be near the Idaho border Wednesday. The equipment is headed for the Canadian tar sands oil development via southern Idaho and Montana. The megaload travels at about 35 mph and is allowed to move only at night.
