Wandsworth council says:
We are consulting on a proposal to introduce a partial one-way on Prairie Street to prevent Heavy Goods Vehicles (HGV) entering the area from Queenstown Road.
The proposals have been developed in response to complaints received by the Council that HGVs are using Prairie Street as means of access to the London Stone Business Estate. The proposals were put forward to the council’s Community Services Overview and Scrutiny Committee in July 2016. The Council’s Executive has approved the proposal subject to the outcome of a public consultation."
