The Internet has huge numbers of websites, or sections of websites, devoted to the history of roads – often created by local enthusiasts.
Here are links to a few of them (all opening in a new tab):
Huddersfield: https://huddersfield.exposed/wiki/Category:Turnpike_roads: this site has articles on nearly all the turnpike roads in the district, as well as items on related topics
Rastrick (Brighouse): Turnpike roads in Rastrick: https://myrastrick.com/turnpike-road-in-rastrick/
Scarcroft (north-east of Leeds): The three milestones of Scarcroft: http://www.thornerhistory.org.uk/wp-content/uploads/2016/03/ms-scarcroft-Ver4.pdf
Wikipedia can also be also a mine of useful information. There are, for example, extensive articles on the Richmond and Lancaster Turnpike, and the Keighley and Kendal Turnpike.
Another interesting site covering all roads in differing amounts of detail is https://www.sabre-roads.org.uk
