Two days earlier, Mr. Pate left a voice mail message for the Transportation Department about “some cracking that’s been observed on the north end” of the bridge, according to a recording from the department released Friday. At both the meeting and in his message, Mr. Pate said the cracking did not present any safety issues.Two days earlier, Mr. Pate left a voice mail message for the Transportation Department about “some cracking that’s been observed on the north end” of the bridge, according to a recording from the department released Friday.

The Transportation Department said the message was not heard until Friday morning. A spokesman for the agency, Dick Kane, said in an email that its representative at the meeting the day before, Alfredo Reyna, was a consultant whose role was chiefly to keep the project on schedule.The Transportation Department said the message was not heard until Friday morning.

“While Reyna is a professional engineer, he does not have control over the project and relies on the expertise of the licensed engineer of record,” Mr. Kane said.“While Reyna is a professional engineer, he does not have control over the project and relies on the expertise of the licensed engineer of record,” Mr. Kane said.
At no point during their communications, the department said, “did Figg or any member of the F.I.U. design-build team ever communicate a life-safety issue.”At no point during their communications, the department said, “did Figg or any member of the F.I.U. design-build team ever communicate a life-safety issue.”
Whether the cracking contributed to the collapse, which killed at least six people in their cars on the eight-lane street below the bridge, remains a key question in the investigation.

Construction crews were working on a diagonal beam at the north end of the structure at or about the time of the collapse, according to information the National Transportation Safety Board provided to local members of Congress. Workers were tightening cables that ran inside the beam.Construction crews were working on a diagonal beam at the north end of the structure at or about the time of the collapse, according to information the National Transportation Safety Board provided to local members of Congress. Workers were tightening cables that ran inside the beam.
Such adjustments, which engineers call “post-tensioning,” are common in concrete designs to fine-tune the structure once it is in place. In this case, however, it was not clear whether the cable-tightening was routine or an urgent undertaking in response to the discovery of the crack in the bridge.Such adjustments, which engineers call “post-tensioning,” are common in concrete designs to fine-tune the structure once it is in place.

Around the same time the meeting was starting, about 9 a.m., Jorge Mesa, a 31-year-old university employee, said he was in his car near the bridge when he heard “a cracking-whip kind of sound.” He looked to his right and saw one of the construction workers on the street.Around the same time the meeting was starting, about 9 a.m., Jorge Mesa, a 31-year-old university employee, said he was in his car near the bridge when he heard “a cracking-whip kind of sound.” He looked to his right and saw one of the construction workers on the street.

Witnesses said the collapse appeared to start near the north end. But no one, including the N.T.S.B., has so far placed any blame for the collapse on the cables or cable-tightening work.Witnesses said the collapse appeared to start near the north end.

“I still think the kid is going to surface,” he said, referring to his niece. “Maybe she’s at some friend’s house. ‘Hey, you had us scared,’ I’ll say to her. I’d give everything I have to bring her back. It just kills me that this is something that could have been prevented.”“I still think the kid is going to surface,” he said, referring to his niece. “Maybe she’s at some friend’s house. ‘Hey, you had us scared,’ I’ll say to her.
