Building record 0164200000 - ICKFORD BRIDGE and Whirlpool Arch Bridge

Bridge consists of 3 three-centred arches on very heavy piers, built of stone & dated 1685. Walling is ashlarded, with chamfered coping & weathered buttresses. On each side of the bridge, facing up and down stream, between the 2 N arches is a cutwater. In the E niche on the S side is a stone inscribed: '1685, Here ends the county of Oxon' & on the N side: 'Here beginneth the county of Bucks, 1685' (B1).
A bridege across the Thame existed here as early as 1237, since in that year Walter de Burgh was ordered to provide the keeper of Ickford Bridge with an oak from Brill for repairs. 'Wodebrugge' and 'Widebrugge' are mentioned in the C13 (B2).
Probably older than 1685. A smaller C18 arch over the stream on the Bucks side of the river Thame (B3).
In good state of repair. Scheduled: SAM BU7 (B4).

The present bridge, which carries the road from Ickford to Tiddington, is actually two bridges within 25m of each other; Ickford Bridge and Whirlpool Arch Bridge. The westernmost Ickford Bridge over the River Thame is an ashlar stone structure of three elliptical arches, two larger ones with a span of about 3m each and a central supporting pier. The third and smaller arch in the western approach causeway acts as a flood arch. The more easterly second bridge known as Whirlpool Arch Bridge, crossing a smaller side stream with a small widening 'whirlpool', is a single stone arch forming a smaller humpbacked structure. Both have been reinforced with iron tie bars with backward 'S' retaining plates. On the main bridge the triangular cutwaters on each side of the northern pier continue upwards to the parapets and form small pedestrian recesses. In the recess on the east of the bridge are two inscribed county boundary stones. There is damage visible in the parapets of both bridges, evidence of the toll that modern wide vehicles have inflicted. Photos (B8).
