Weymouth and Portland street lights to go off at night
Work is to begin to convert street lights in a Dorset town to switch off overnight.
Dorset County Council is to begin the 10-week operation to allow 5,100 lights in Weymouth and Portland to switch off between 00:00 and 05:30 GMT.
The lights will only switch back on again in the morning if it is still dark.
About 2,800 lights will remain lit all night. The move is aimed to save money and reduce carbon emissions.
The Conservative-run authority said the part-night lighting scheme will be extended to all towns and villages in the county over the next two years and is part of plans to save £55m over three years.
Street lights in Dorchester have already been converted. Charmouth and the Piddle Valley have also trialled the scheme.
The work in Weymouth, Portland and nearby Chickerell will begin on 21 November.
