Vehicle plows into crowd on Bourbon St., with 14 fatalities

Nobody has really said why they needed maintenance. Just that they were doing maintenance on them in preparation for the Super Bowl. Being maintenance, I assume it was to make sure they properly functioned during the Super Bowl, not a situation where stuff was stuck in them and they needed to be repaired.

It's been awhile since I looked at them, and I never really took a very close look obviously, but my recollection is that there isn't much of a gap where stuff could fall in and get stuck.

they are in the process of being replaced because the old ones kept getting stuck.

“Bollards were not up,” Mayor LaToya Cantrell told reporters during a press conference on Wednesday. The replacement project began in November and is “near completion, with the expectation of being completed before the Super Bowl,” she said.

The “broken-down” bollards were “inefficient” and often had Mardi Gras beads stuck in the machinery, according to Cantrell.
