Roman bridges, built by ancient Romans, were the first large and lasting bridges built.
Roman bridges were built with stone and had the
archas its basic structure. Most utilized concrete as well.
142 BC, the Pons Aemilius, later named "Ponte Rotto" (broken bridge) is the oldest Roman stone bridge in Rome, Italy.
The biggest Roman bridge was
Trajan's bridgeover the lower Danube, constructed by Apollodorus of Damascus, which remained for over a millennium the longest bridge to have been built both in terms of overall and span length. They were most of the time at-least 60 ft above the body of water.
The longest Roman stone arch was probably
Severan Bridgeof 34 m, but there are indications of longer arches. An example of temporary military bridge construction are the two Caesar's Rhine bridges.
