SP7233 : Thornborough Bridge"Nothing appears to be known about the history of Thornborough Bridge, which carries the road from Buckingham to Fenny Stratford across the Claydon Brook. It is by far the oldest bridge in the whole of Buckinghamshire, and possibly may be the one called Totisbrigge in a Presentment of 1389, and described as being in the parishes of Thornborough, Leckhampstead and Foxcott. It was stated that Totisbrigge was broken, and a proposal was made the the Hospital of St John the Baptist at Oxford should repair the foot of the bridge and one arch on the Thornborough side, and the men of Leckhampstead and Foxcott the foot and two arches on their side.
"The present bridge has six stone arches, pointed in shape, with double arch-rings built in two orders. Two arches have four chamfered ribs. On the upstream side and three cutwaters with recesses, but downstream there are none. In place of these there are two small buttresses and a large rectangular recess carried by an extension of one of the piers. The total span is 42 yards and the width between the parapets measures about 10 feet."
