 | | The Tower Bridge is, however, of such importance and interest, both on account of the problems that it has solved, and from the manner in which it has solved them, that this great framework of metal and masonry, so familiar to the Londoner, deserves inclusion among the chief engineering feats of modem times. |
 | | Technically, it is a three-span bridge, the two outside spans of the suspension type carried on stout chains that pass at their landward ends over abutment towers of moderate height to anchorages in the shore, and at their river ends over very lofty towers, themselves connected at an elevation of 143 feet above high-water level. |
 | | The most notable feature of the Bridge, unless we except the unique combination of steel and masonry work in the towers, is the method of enabling traffic, pedestrian and vehicular, to cross the 200-foot space between the towers, at the level of the roadway of the two outer spans. |
