Página 3 - ... valuable positive results, if we confine our attention at first to the comparative weights of iron required in the different methods of constructing the superstructure, which, after all, is by far the most important element in determining the cost of a long-span bridge. The size of a bridge is very commonly the popular standard by which the eminence of its engineer is measured ; we may, therefore, naturally expect to find engineers ambitious of excelling one another in this particular branch...
