The St Saviour’s Dock footbridge is likely to be closed from Thursday 1 November.
Closure was expected two weeks ago but the crossing has remained open.
When the diversion comes into operation on or shortly after Thursday it will stay in place for up to six months.
The alternative route is:
At the west end of Bermondsey Wall West, bear left to follow Mill Street past Vogan’s Mill to the main road.
Holy Trinity Church Dockhead is to the left. Go right past the Co-op to have a good view (right) down St Saviour’s Dock.
Go right again to enter Shad Thames which into the late 20th century was noted for a strong smell of spices. Here are Jamaica Wharf, St Andrew’s Wharf and Java Wharf.
At the far end the road bears round to the left past Tea Trade Wharf (right) and under a bridge (the old Design Museum) to a junction. Turn right up steps for the River Thames and rejoin the main route on Butler’s Wharf.
Go left towards Tower Bridge.
