The Chief addressed this earlier jn post 218: "The resumption of cruising, just like commercial shipping, will not depend on rebuilding the bridge, only on removing the debris from the shipping channel, not even the outer arches which are outside the channel. But, yes, it will take 2-4 months to accomplish that. "
Somewhere along the way it was mentioned that commercial traffic will likely resume before passenger cruising. It does seem likely as well as logical, but I was surprised that when were on the Mississippi back in October and were significantly delayed by barge traffic, the captain told us that passenger traffic (at least right then) had priority and so we got to go while the tows waited. Perhaps that was a unique situation for a given day and time.
