Months before the deadly New Orleans vehicle attack on New Year’s Day, the city modeled scenarios for how an attacker could enter Bourbon Street at various intersections in a crew-cab Ford F-150 similar to the one used to kill 14 people and injure dozens more. Engineers found such a pickup could enter the crowded tourist strip at speeds ranging from 12 to 70 mph - and yet city officials are now installing new street barriers that can only withstand 10-mph impacts, according to an April city-contracted engineering analysis and city bid documents reviewed by Reuters. Those new barriers, known as “bollards,” had not yet been installed on Bourbon Street on New Year's but are planned to be completed by the Feb. 9 NFL Super Bowl in New Orleans.
