It is one thing to design a bridge.  It is another thing to build it.  Planning and executing the construction of a bridge is often very complicated.  The construction work is potentially the main problem to existing traffic and to normal life in the area, especially when large local fabrication works have to be installed.

Even before any actual construction is done, substantial work is needed in the form of tests.  Boreholes will be made to check the condition of the ground, together with any available geological maps.  In the case of a river or sea crossing, records of water levels and velocities will be needed. Models of the bridge or of parts may be tested aerodynamically and hydrodynamically, and of course mechanical tests will be made.

Concrete is a mixture of paste and aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.

Within this process lies the key to a remarkable feature of concrete: it's plastic when newly mixed, and strong when hardened. These qualities explain why one material, concrete, can build skyscrapers, bridges, superhighways and houses.

Ready-mixed concrete, is the most common form. It's batched at local plants for delivery in the trucks with revolving drums. Precast products range from concrete bricks and paving stones to bridge girders and structural components.

The Snowdon Mountain Railway has always been a tourist attraction only. Opened in 1898 its only purpose is to carry people up Snowdon, the highest mountain in England and Wales.[pic 1]

The gauge is 800 mm – a popular size used by many mountain railways.  

Each train consists of one carriage that holds 54 people; this is pushed up the mountain by a steam or diesel locomotive. The speed is 5 mph giving passengers plenty of time to admire the landscape.

There are totally independent brakes on the carriage which are not coupled to the locomotive for safety reasons. Should the train ever start going too fast, the brakes would be automatically applied.
