>The seven highway workers and inspector on the Key Bridge at the time were not notified of the Dali’s emergency situation before the bridge collapsed. We found that, had they been notified about the same time the MDTA Police officers were told to block vehicular traffic, the highway workers may have had sufficient time to drive to a portion of the bridge that did not collapse. Further, we found that effective and immediate communication to evacuate the bridge during an emergency is critical to ensuring the safety of bridge workers.
