The total evacuation triggered by a bomb hoax on 12 September 2001 (the day after the September 11 attacks destroyed the twin towers of the World Trade Center in New York City) showed that the bridge would not be useful if both towers need to be emptied simultaneously, as the capacity of the staircases was insufficient for such an event.
Evaluasi pengosongan dipicu oleh ancaman bom palsu pada 12 September 2001 (sehari setelah tragedi kehancuran menara kembar World Trade Center di New York) menunjukkan bahwa jembatan tersebut tidak berguna selama kedua bangunan perlu dikosongkan serentak, karena muatan tangga darurat tidak cukup untuk menghadapi kejadian seperti ini.
