1) The West Riding Book of Bridges was commissioned in 1753 so that the Justices of Peace knew exactly what their responsibilities were.
It was lodged with the Clerk of the Peace and contains plans and elevations of 120 bridges, written accounts of them, and information about the Riding’s obligations for their maintenance. Further plans were included between 1758 and 1766 to take account of structural alterations. A Book of Reference for 1752, made by the Bridge Undertakers, lists over 400 bridges and defines them under the headings: Riding
Individual. These replaced earlier books, although little appears to be known about them. The Bridg booke for the North Riding is mentioned in 1608, in assessments for bridges at Ayton and Catterick, whilst in 1640 Bawtry Bridge was in the booke of bridges to be repaired at the chardge of the whole West Riding.
