Preliminary investigation a Space Age semi-tractor pulling two tanker trucks was eastbound on I-84 near milepost 54. The driver, James Altman, age 34 from Portland, was driving too fast for the snowy conditions on the roadway. Altman lost control of the commercial motor vehicle and the tankers flipped onto their sides. When the tankers flipped they started leaking onto the diesel onto the highway. The diesel eventually seeped underneath the barrier onto the westbound lanes of travel. Two tanks completely spilled their diesel.
