Apparently it was fared into the forward superstructure. The only drawing I've ever seen is the one in "Damned by Destiny", which is what Alvama used for his reference. I've just found a picture of a model of Bretagne. It doesn't show a distinct bridge either. You can also see the side-by-side funnels. Very bizarre design, and little wonder it was rejected in favor of a modified Normandie design.
