The helicopter crash at Vauxhall has obviously closed the Thames Path.
An inland diversion is far to long.
Upstream walkers arriving at Vauxhall Bridge should go under the bridge. Once up the slope at St George’s Wharf bear sharp right to go up another slope to the bridge.
Walk across Vauxhall Bridge.
On reaching the north side at Pimlico turn left down steps to stay with the river. It will be necessary to walk round a house but there is a path as far as St George’s Gardens.
After that the road is by the river to the next bridge.
Cross Chelsea Bridge to return to the south side and at once go right into Battersea Park.
