Abstract:
The bridges of the world that have stood the greatest test of time are arches. Some of the stone arches built by the Romans over two thousand years ago are in good condition to-day. These arches were without reinforcement and if an arch properly built of stone will stand for ages, one of concrete and steel is the very best type that can possibly be built. Arches are by far the strongest type of bridge construction, as an arch can be so designed that the entire strain will be compressive instead of tensile. There is an impression that arches are not practical in level countries, which is not so in the opinion of the writer. We have been building arches in the level sections of Illinois with the very best of results.
