viaduct, type of long bridge or series of bridges, usually supported by a series of arches or on spans between tall towers. The purpose of a viaduct is to carry a road or railway over water, a valley, or another road.
Why is it called a viaduct and not a bridge?
A viaduct is a long bridge-like structure carrying a road or railway across a valley or other low ground. Bridges are built across rivers or arms of the sea, whereas viaducts tend to cross valleys and low lying areas where there may or may not be a river.
What makes a viaduct A viaduct?
A viaduct is a specific type of bridge that consists of a series of arches, piers or columns supporting a long elevated railway or road. Typically a viaduct connects two points of roughly equal elevation, allowing direct overpass across a wide valley, road, river, or other low-lying terrain features and obstacles.
When was the first viaduct built?
The first viaduct was constructed as part of the Kilmarnock and Troon Railway, which opened on 6 July 1812. It is located at National Grid Reference NS 3834 3690. It was built with four segmental arches of 12.3 m (40 ft) span, and a rise of one-third span; the voussoirs were 610 mm (24 in) thick.
What is a viaduct made of?
Viaducts usually consist of a series of multiple bridges connected by a series of arch structures or spans between tall towers made of stone, concrete, iron, or steel.

A viaduct usually refers to long bridges or series of bridges connected to one another by arch bridge structures that carries a road or a railway across a valley or a gorge.
How long did it take to build the viaduct?
The Engineering Challenge
The iconic Bennerley Viaduct was constructed in an 18 month period in 1877 and 1878 as a bespoke engineering solution to overcome this engineering challenge.
What is the oldest viaduct in the world?
The Sankey Viaduct is a railway viaduct in North West England. It is a designated Grade I listed building and has been described as being “the earliest major railway viaduct in the world”. In 1826, the Liverpool and Manchester Railway Company (L&MR) was authorised to construct the world’s first intercity railway.

Why did they put roofs over bridges?
To keep snow off the bridge roadway in the winter. In areas with very high snowfall, such as Vermont, the weight of snow could demolish a wooden bridge (as most were). A sloping roof allowed the snow to fall harmlessly into the river.
Who built the viaducts?
Construction began in late 1869. It necessitated a large workforce, up to 2,300 men, most of whom lived in shanty towns set up near its base.

What happened to the Titanic’s bridge?
Wreck. The bridge was destroyed when the first funnel toppled over on it. The prominent feature that remains is the bronze telemotor for the ship’s wheel and the base mountings for the walls of the wheelhouse. The bridge wing cabs on both sides broke up and collapsed.
Why do bridges have triangles?
Truss bridges often use equilateral and isosceles triangles to distribute weight because the equal angles allow forces to spread evenly across the bridge. Triangles are one of the best shapes for distributing weight because they take force from a single point and distribute it across a wide base.
What is the leg of a bridge called?
Piles
Piles and Piers
You can think of them as the legs of the bridge because they look just like your legs when you’re standing. Piles are slender vertical supports that are driven into the ground below a bridge, even if that ground is below water.
