The bridge straddles the parish boundaries of Thornborough and Buckingham, where the parish boundary follows the line of Padbury Brook (also known as The Twins), a tributary of the River Great Ouse. Dating back to the end of the 14th century,[1][2] it is the only surviving mediaeval bridge in Buckinghamshire. The parish division is marked by a boundary stone in the middle of the bridge.[3]

The stone bridge measures approximately 30 m (98 ft) long and 4 m (13 ft) wide, spanning the river with six low arches .[4] Three refuges are formed within the parapet on the south side.

The bridge is Grade I listed by English Heritage.[5]
