Four stars - for a good read. I particularly liked the introductory 'history of roads'. Roads not only provided essential physical communication but fostered civilisation itself.
Telford's work on roads, bridges, canals, drainage and architecture is fully covered.
Telford's character comes across as hardworking, honest and friendly. He was very capable, with a strong belief in the importance of practical experience: he began his career as a mason. He was very thorough and carried out tests to verify that his designs would work.
Telford was too busy and too single-minded to marry (I assume) because nothing is said of his relationships with women. What I did not expect was his interest in writing poetry - when he felt moved, or had time on his hands.
I recommend this book for anyone interested in the industrial history of 19th century Britain. There are no illustrations, unfortunately - but this as is a freebie I have no complaints.
