Last shown on the 1971-73 1:2,500 OS Plan when the bridge didn't have a pavement on the western side. The 1980-81 1:1,250 OS Plan clearly shows the incomplete bridge widening works to the west and the site of the FB is now in the body of the bridge. This image shows the most recent 1970s widening as semi-circular concrete http://www.abingdonblog.co.uk/imag06/06042806.jpg. Definitely destroyed.

The 1936 map shows a stone on the west side of the west parapet, south of the river bank with BM 170.30ft (51.9m). Also shown on the 1967 and 1971 maps. Other Old-maps show a boundary stone on the west side of the east parapet as BM 179.1ft (54.6m). I could find neither stone.

You can get a reasonably good view of the part of the bridge the FB should have been from a nearby open area. The FB was not visible from there.

Agree I couldn't find any sign. I suspect that the W battlement is more recent than the E, looks as though the road was widened on the west side. Sort of confirmed by looking under the bridge. An article on Medieval Bridges in Oxfordshire - see www.wantage.com/museum/Local_History/Medieval%20Bridges%20in%20Oxfordshire.pdf says the bridge was re-built in 1979-80.

Old stone bridge. No sign of FB: possibly under footway, or lost to stonework repairs if on W face of abutment. Proximity of G3646 suggests it may have gone.
