Bridges
In a bridge, the wing walls are adjacent to the abutments and act as retaining walls. They are generally constructed of the same material as those of abutments. The wing walls can either be attached to the abutment or be independent of it. Wing walls are provided at both ends of the abutments to retain the earth filling of the approaches. Their design period depends upon the nature of the embankment and does not depend upon the type or parts of the bridge.
The soil and fill supporting the roadway and approach embankment are retained by the wing walls, which can be at a right angle to the abument or splayed at different angles. The wing walls are generally constructed at the same time and of the same materials as the abuments.

Famous quotes containing the word bridges:
“If the Revolution has the right to destroy bridges and art monuments whenever necessary, it will stop still less from laying its hand on any tendency in art which, no matter how great its achievement in form, threatens to disintegrate the revolutionary environment or to arouse the internal forces of the Revolution, that is, the proletariat, the peasantry and the intelligentsia, to a hostile opposition to one another. Our standard is, clearly, political, imperative and intolerant.”
—Leon Trotsky (1879–1940)
“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)
“As night is withdrawn
From these sweet-springing meads and bursting boughs of May,
Dream, while the innumerable choir of day
Welcome the dawn.”
—Robert Bridges (1844–1930)
