Think bridge security will be hightened over the next few days?
I don’t know how you heighten bridge security. There are so many bridges with such heavy traffic it seems an impossible task.
Really looks like structural failure, and probably not unless they have good intel. Unless it’s a new style or group of terrorism, this doesn’t fit the MO. Bridges would have been blowing up or crashing all over the place already, and something would have been in place to kill the first responders to each incident.
