A hole and subsidence has caused a section of the Wanganui riverbank walkway behind the railway yards to be closed.

Wanganui District Council has temporarily shut part of the riverbank walkway between the Cobham Bridge and City Bridge as a deep hole, about a metre long by half a metre wide, has developed at one of the narrowest points of the walkway.

Barriers have been erected to stop access.

The sinkhole has developed because the walkway is slipping toward the river and the council is working to remedy the problem. It is not known how long the walkway will remain closed.
