Crews on the Mississippi River installed the last of the steel tub girders this week on the new Red Wing bridge, completing the center span of the $63.4 million construction project.

The assembled girder was transported down the river where cranes on barges were then used to lift it into place.

Tub girders are hollow beams that will support the driving surface on the bridge. The new Red Wing bridge is supported by three sets of girders placed side by side.

The bridge project is scheduled to be completed in 2020.
