The bollards on Bourbon Street were installed in 2017 following the 2016 terrorist truck attack in Nice, France, where a man claiming to be part of the Islamic State killed 86 people and injured over 400 by driving a large truck through a pedestrian mall.

Plaintiffs argue that the timing of construction left vulnerable gaps in security, effectively creating a “soft target” that attacker Shamsud-Din Jabbar exploited when he drove a rented pickup truck through a crowded Bourbon Street, killing 14 people and injuring dozens more.
