Cracks observed prior to Miami bridge collapse pointed to design flaws, NTSB says

As part of its ongoing investigation into the deadly collapse of a pedestrian bridge in Miami, Florida, earlier this year, the National Transportation Safety Board has released a new update saying that the bridge suffered from several key design flaws.

Nineteen days prior to the collapse, which killed six and injured eight others on March 15 on the campus of Florida International University, a series of cracks was observed on both the south and north ends of the bridge.

Two days before the bridge fell, the lead engineer on the project left a voicemail with state officials saying cracking had been seen on the north end of the span that had been earlier moved into place during accelerated construction.
