The Coronado Bridge does not have to be dismantled to allow carriers to pass. First of all, all the Navy's big carriers moor at North Island N.A.S., before you get to the Coronado Bridge. Second, the largest ships that do need to moor beyond the Coronado Bridge are the LHAs (i.e. Tarawa-class) amphibious assault carriers at 32nd Street N.A.S. They pass under the Coronado Bridge with no difficulty at all.

The Coronado Bridge indeed was built modularly (I saw it being built), but it is not disassembled for any ship.

You take a look at this picture:

Now would you explain to me how the heck an aircraft carrier is going to pass underneath a bridge with clearance that low and that narrow?
