The state Transportation Department says drivers from Portland to Seattle might encounter a large load on Interstate 5 overnight Friday and early Sunday.

A B-1 bomber fuselage owned by Boeing is being trucked from Portland International Airport to Boeing Field in Seattle. It will take up all the lanes in some place on the freeway.

Four or five Washington State Patrol cars are escorting the bomber. It leaves Portland about 11:30 p.m. Friday. Traveling about 30 mph, it's expected in the Olympia area by 6 a.m. Saturday. It's scheduled to leave Olympia at 2:30 a.m. Sunday and reach Boeing Field by 6:30 a.m. Sunday.
