Blog – Bridge Segment Placement

Once the Selmon Extension bridge segments are produced, they’re transported from the off-site casting yard on an over-size transport. Next, they’re hauled to the west end of the Extension ramp, where the straddle carrier, picks it up, takes it up the ramp, then releases it to the launching gantry that will set the segment. Finally, everything is pulled together with post-tensioning (not pictured) and the operation is repeated with the next segment.
