Part 1 of this newly published volume contains a detailed history of turnpikes while Part 2 gives detailed histories of the 24 turnpikes that existed in Buckinghamshire, including sections that ran into other counties. Of particular interest are two which penetrated deep into Hertfordshire - The Sparrows Herne turnpike (from Bushy, via Berkhamsted and Tring, to Aylesbury) and the Reading to Hatfield turnpike which ran through Rickmansworth and St Albans.
I have also updated the subject page on Turnpikes
