Cracks found in a Florida pedestrian bridge prior to its collapse, killing six, might have indicated the upcoming failure.

A key concrete support truss in the doomed Florida International University pedestrian bridge developed worrisome cracks 10 days before the structure was lifted into place over the Tamiami Trail, photographs and an internal email unintentionally released by the school show.

The documents, released in response to public records requests from the Miami Herald, show that FIU’s construction and engineering team discovered potentially problematic cracks in the bridge earlier than officials have previously acknowledged.

Because of the ongoing investigation we do not yet how the engineering company building the bridge responded to the cracks. They might have analyzed them and dismissed them. Or the might have ignored them entirely.

    I find this strange.

    Why would the operator move the crane 30 blocks to “clear the area for emergency workers”. The crane itself would be a vital piece of equipment in any rescue attempts.

    I think it is obvious that the crane which was lifting the tensioning equipment to the top of the structure to facilitate the workers activities but the crane itself was certainly not a part of the failure. I suspect that the crane operator, probably the owner, wanted to somehow limit liability.

    But his removing the crane might be seen as an irresponsible act that may have cost lives. (?)
