Records of Westminster Bridge Commissioners, comprising volume of draft contracts and papers relating to the Bridge, including 'Act for building a Bridge cross the River Thames, from the New Palace Yard in the City of Westminster, to the opposite Shore, in the County of Surry' and articles of agreement and contracts for various aspects of building the bridge and provision of materials.

The volume is a later re-binding, possibly of the 19th century. The contracts had been paginated, and so, presumably, bound together at an earlier date. The pagination runs from 153 to 261, the right hand (odd) pages only being numbered; the surviving items thus appear to be part only of an earlier compilation. From the note made and signed by Taylor White on p.207, and the endorsements on pp [194] and [208], it appears likely that the papers were among the working papers of the Commissioners themselves.
