In the aftermath of Hurricane Ivan, the twin spans of Interstate 10 across EscambiaBay near Pensacola resembled a mouthful of bad teeth, all gaps and snaggles.
One force all bridges have to contend with is the "scour factor," the impact of fast-moving water on the soils around bridge pilings.
Bridges are designed with the scour factor in mind and are inspected regularly to make sure the soils around the supports are acting as expected, Kile said.
By the time the surge struck the bridge structure, it reached points near the top of the deck, trapping air between the girders and generating a massive uplift.
As the superstructure moved laterally, often at an angle to the bridge, it had twisted and dragged piers down with it.
In addition to the new substructures, the contractor had to realign 16 spans on the westbound bridge and substitute 12 superstructure spans taken from the eastbound bridge.
