(YAHOO) – The U.S. National Transportation Safety Board said on Thursday that “design errors” were found in a pedestrian bridge that collapsed in March at Florida International University, killing six people and injuring eight.
The board’s investigation update said there were errors in the design of part of the 174-foot (53 meter) Miami span, and that resulted in overestimating the capacity of a critical section. The NTSB said concrete and steel specimens tested met the project’s build plans’ minimum requirements.
A crack in the bridge that was observed prior to the collapse and previously disclosed was “consistent with those errors,” the board said.
The 950-ton, $14.2 million bridge, which crossed an eight-lane highway adjacent to Florida International University (FIU) in Miami-Dade County and linked the campus to the city of Sweetwater, collapsed five days after it was installed.
