Duration of Pile Bridges
Perhaps one of the most well-known of the medieval pile bridges, and one that was probably similarly constructed as a pile bridge by the Romans, are the older versions of London Bridge. However even when the first version of the bridge as a stone structure, was commenced during the reign of Henry II in 1176, oak piles were used as part of the construction. Indeed some of those piles while driven in 1176 were still sturdy enough to be drawn in 1921, almost 750 years later.

Famous quotes containing the words duration of, duration, pile and/or bridges:
“What matters it that man should have a little more knowledge of the universe? If he has it, he gets little higher. Is he not always infinitely removed from the end, and is not the duration of our life equally removed from eternity, even if it lasts ten years longer?”
—Blaise Pascal (1623–1662)
“This pond never breaks up so soon as the others in this neighborhood, on account both of its greater depth and its having no stream passing through it to melt or wear away the ice.... It indicates better than any water hereabouts the absolute progress of the season, being least affected by transient changes of temperature. A severe cold of a few days’ duration in March may very much retard the opening of the former ponds, while the temperature of Walden increases almost uninterruptedly.”
—Henry David Thoreau (1817–1862)
“There is the guilt all soldiers feel for having broken the taboo against killing, a guilt as old as war itself. Add to this the soldier’s sense of shame for having fought in actions that resulted, indirectly or directly, in the deaths of civilians. Then pile on top of that an attitude of social opprobrium, an attitude that made the fighting man feel personally morally responsible for the war, and you get your proverbial walking time bomb.”
—Philip Caputo (b. 1941)
“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)
