The work to put a permanent replacement span on the Interstate 5 Skagit River bridge that collapsed in May is at a crucial stage.
The Transportation Department says eight huge girders are being moved into place next to the temporary span.
Spokesman Dave Chesson in Burlington says three were delivered Tuesday; three are arriving Wednesday; and the last two on Thursday.
Each one is 162 feet long and weighs 84 tons.
Moving each girder into place is a tricky maneuver that requires two cranes -- one on a floating platform in the Skagit River.
Chesson says the work is on track to move the permanent replacement into place after Labor Day.
