Bridges
Roman bridges were among the first large and lasting bridges ever built. They were built with stone, employing the arch as basic structure. Most utilized concrete as well. Built in 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 bridge over 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 normally at least 18 meters above the body of water.
An example of temporary military bridge construction are the two Caesar's Rhine bridges.

Famous quotes containing the word bridges:
“... this single span,
Reaching for the world, as our lives do,
As all lives do, reaching that we may give
The best of what we are and hold as true:
Always it is by bridges that we live.”
—Philip Larkin (1922–1986)
“And Reason kens he herits in
A haunted house. Tenants unknown
Assert their squalid lease of sin
With earlier title than his own.”
—Robert Bridges (1844–1930)
“There is nothing in machinery, there is nothing in embankments and railways and iron bridges and engineering devices to oblige them to be ugly. Ugliness is the measure of imperfection.”
—H.G. (Herbert George)
