Context of transport in
England pre 1700
Turnpike Roads in the 18th century
Transport pre 1700
• Rich rode and poor walked - goods by cart or
pack horse…………
• Roman Roads linking key Forts and early canals –
but largely left to decay for centuries
• 16th C focus on rivers and navigation
improvements
• 1663 First Turnpike Act; Commercial Turnpike
Trusts established in 1706 - Toll roads (but 50 years
on for major impact – road engineering by blind John
Metcalfe)
The industrial revolution was full on energy, enterprise and
hard graft – but not pretty
Industrial Revolution

1709 - Abraham Darby (1) - Iron works at
1761 - Bridgewater Canal
1764 - Arkwright’s Spinning Jenny
1774 - James Watt - rotary steam engine
1771 - World’s first factory established
1770s - London Stock Exchange created
Industrial Revolution impossible without
affordable means of moving goods for trade,
raw materials and finished goods - and for
making urbanisation and factory production
possible for domestic and international
markets

Coal
Iron
Textiles
Agricultural supplies
Manufactured goods
Also impossible without pioneering designer/engineers
whose vision, skill, energy, determination and enterprise
would drive projects through to conclusion.
“The men who built our bridges, docks, lighthouses,
canals and railways were mostly country bred boys who
were originally hands-on craftsmen and self taught in the
science, technology and arts of their projects. They laid
the foundations of what became the civil engineering
profession” (Rennie was the exception)
Brindley, Smeaton, Jessop, Metcalf and Telford
Canals and Rivers in England and Wales
“ The opening up of the internal communications of a
country is undoubtedly the first and most important
element of its growth in commerce and civilisation.”
Richard Cobden (1804 – 1865)

Telford’s Philosophy
“We do not consider anything to be impossible. Impossibilities
exist chiefly in the prejudices of mankind , to which some are
slaves and from which few are able to emancipate themselves and
enter on the path of truth.” (Bridge over the Danube)
He admired commercial enterprise and its activity, energy and
intelligence. “But I hold that the aim and end of all ought not
to be a bag of money, but something far higher and far better.”
A tribute from Robert Southey Poet Laureate and close friend
“ Telford’s is a happy life; everywhere making
roads, building bridges, forming canals and
creating harbours – works of sure, solid,
permanent utility; everywhere employing a
great number of persons, selecting the most
meritorious, and putting them forward in the
world in his own way.”
Telford’s Influential Legacy lives on
• Designed and built to last!
• Pivotal role in a national transport system
• Pioneered and developed the engineering
design and project management techniques
• International figure
• First President; Institution of Civil Engineers
• Influence on Victorian Red Brick universities?
