The bridge collapsed Tuesday after a large cargo ship crashed into it, following a mayday call shortly before the collision. Two construction workers died; four are missing and presumed dead.

An operation to remove the ship, clear out debris and reopen the channel began Saturday, officials said.

"Parts of the non-federal channel are already being worked on and there
