My wife and I returned a few days ago from a vacation in England. At one point, we walked across the Westminster Bridge, where earlier this year an Islamic terrorist drove a vehicle into a crowd of pedestrians, killing four and injuring more than 50. Since that attack, barriers have been erected between the roadway and the pedestrian paths across the bridge. They are referred to by some as “diversity bollards.” In addition, perhaps because the Nice terrorist got his truck onto the Promenade inside of whatever barriers existed on the road, there are roadblocks at the ends as well, so that a driver can’t circumvent the bollards.
So pedestrians are safe as they cross the bridge. I took this photo from around the middle of the bridge:
