Vulgarity certainly cannot be charged against any integral portion of the great work itself. There is nothing frivolous and nothing ostentatious even in the details which we have noted, and in which we have not been so much criticising the crowning work of a great engineer’s career as noting the spirit of our age. It is scarcely fair to say, even, as was said by an architectural journal when the completion of the bridge was doubtful, that if it were left incomplete its towers would stand “in unnecessary ugliness.” Its defects in design are not misdeeds, but shortcomings. They are the defects of being rudimentary, of not being completely developed. The anatomy of the towers and of the anchorages is not brought out in their modelling. Their fingers, so to speak, are all thumbs. Their impressiveness is inherent in their mass, and is what it could not help being. The ugliest of great bridges is undoubtedly Stephenson’s Britannia Bridge; and this is ugly, not because it is square and straight, but because it tells nothing of itself. It is a mere flat surface, and almost absolutely inexpressive, compared, for example, with such a piece of iron-work as the truss which carries the roadway of the bridge over Franklin Square, in which the function of every joint and member is apparent. But a far nobler thing than this is the central span of the great bridge itself, its roadway slowly sweeping upward to meet the swift swoop of its cables. We have complained of the lack of expression in the towers of their anatomy, but this is anatomy only, a skeletonized structure in which, as in a scientific diagram, we see--even the layman sees--the interplay of forces represented by an abstraction of lines. What monument of any architecture can speak its story more clearly and more forcibly than this gossamer architecture, through which its purpose, like “the spider’s touch”-- “So exquisitely fine, Feels at each thread, and lives along the line”?
