Thornborough Bridge is situated on the original Bletchley to Buckingham road, now bypassed by a modern bridge in 1974 for the A421. The bridge is accessible to pedestrians from an adjacent lay-by. The bridge straddles the parish boundaries of Thornborough and Buckingham, where the parish boundary fo
llows 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, it is the only surviving mediaeval bridge in Buckinghamshire. The parish division is marked by a boundary stone in the middle of the bridge. The stone bridge measures approximately 30 m (98 ft) long and 4 m (13 ft) wide, spanning the river with six low arches. Three refuges are formed within the parapet on the south side. The bridge is Grade I listed by English Heritage.
