THE SUSPENSION BRIDGE.
In the same vicinity, and over the same strait, is the great suspension bridge, which, when it was finished in 1826, was deservedly esteemed one of the wonders of the world, and is still entitled to hold that rank. It is indeed a stupendous structure, of which the full details may be learned from the official reports; but the following are among the principal facts. It is one hundred feet above the water, so that the ships, even those of a large size, are not impeded, and can pass under it without lowering a sail or a spar. The bridge is built out upon arches from both sides of the river, to a certain distance, leaving the space between the points of suspension, five hundred and sixty feet. The platform is about thirty feet wide. The whole is suspended from four lines of strong iron cables, by perpendicular iron rods, five feet apart. The cables pass over rollers, on the tops of pillars, and are fixed to iron frames under ground, which are kept down by masonry. The weight of the whole bridge between the points of suspension is four hundred and eighty-nine tuns. The massy materials of which this bridge is composed, the admirable manner in which they are locked together, the great elevation at which it crosses this grand strait, its persistence without sign of failure during more than a quarter of a century, its importance as a connecting link between England and Ireland, and the result of this early effort to conquer formidable physical difficulties, fill the beholder with admiration and delight, and do lasting honor to Mr. Telford, the distinguished architect.
