Portland, OR -

A megaload of oil refinery equipment bound for western Canada has completed a leg of more than 40 miles in its planned six-day trip through Eastern Oregon.

State Department of Transportation spokesman Tom Strandberg says the load parked Tuesday south of Pendleton.

It left the Port of Umatilla Monday night despite protests from environmentalists and tribal members.

The previous night, two men locked themselves to it. By the time officers detached them, it was too late for the rig to make it to its first stop site.

The load is 22 feet wide, 380 feet long. It's allowed to move only at night to reduce traffic delays.

Strandberg said he didn't know whether the 450-ton load would resume its trip Tuesday night. Snow created difficult travel conditions in the region.
