Road infrastructure includes roads, bridges and tunnels. By the late 18th and early 19th centuries, new methods of highway construction had been pioneered by the work of three British engineers, John Metcalf, Thomas Telford, and John Loudon McAdam, and by the French road engineer Pierre-Marie-Jerome Tresaguet.
Metcalf was the first professional road builder to emerge during the Industrial Revolution. Tresaguet established the first scientific approach to road building and Telford made substantial advances in the engineering of new roads and the construction of bridges. McAdam designed the first modern roads through the development of an inexpensive paving material.
London townscape model
This plaster architectural sculpture of the City of London, showing the road infrastructure and buildings, is the London cityscape model made by the firm Chisel & Mouse. The company takes GIS (Geographic Information Systems) mapping data and applies its 3D technology in order to produce a printed 3D building city map. The City of London is where London originally developed within the Roman city walls and is a city in its own right, separate from the rest of London. It is roughly one square mile in area between the Temple Bar memorial pillar and the base of Tower Hill. Donated by Chisel & Mouse
