Why don’t The Powers That Be simply take the technology that was going to be applied to building a temporary port for the Gaza Strip, and setting it up OUTSIDE the collapsed bridge? That would be a good use of available resources, and get the port of Baltimore back into operation at limited capacity. No port facilities were damaged. Once the bridge debris is cleared the port will be back in operation. The temporary floating pier that the Navy is building in Gaza is for use only with specially-designed roll on-roll off ships that the Navy operates, not with normal container ships. Building a temporary pier outside of the bridge area would do nothing to get shipping back in operation.
The port operations will be delayed somewhat (X months) until they can clear the channel.
The bigger issue is the vehicle traffic. The bridge was used for trucks with hazmat , which are not allowed through tunnels. That traffic nightmare will be there for the foreseeable future.
I would not want to be a OTR trucker heading towards the NE. It has always been congested , now only more so.
