Input: Question: Which bridge that crosses the cut also crosses the Jubilee river? Passage:The cut, is crossed by Ham Bridge from the rest of Old Windsor to Ham Island. Much smaller Lion Island is at the top where the flows split. Then Albert Bridge crosses to Datchet including at its lowest point, the thin island of Sumptermead Ait. On the Windsor side (right bank), the river winds round farmland at Princes Consort farm and Windsor Castle Home Park. There follows Victoria Bridge connecting the upper end of Datchet then a golf course, followed by Black Potts Railway Bridge. The railway bridge has a great brick pier in Black Potts Ait, behind which the Jubilee River rejoins the Thames. The left bank becomes playing fields of Eton College. The area known as Black Potts up to Romney Island is an attraction where those fishing have included Isaak Walton who wrote a major work which promoted angling and Charles II in the century before.
