Angry motorists claim work to lay a new gas main has caused a traffic nightmare on a main highway between Mexborough and Denaby.
Drivers say temporary traffic lights at the junction of Doncaster Road and Pastures Road have caused delays of up to 30 minutes for commuters and parents who are on the school run.
The National Grid is laying nearly 800 metres of new gas mains in Mexborough to meet what it describes as an increased demand for gas in the area.
Conisbrough resident Wendy Collins said the scheme was “causing chaos.”
She added: “Travellers were left with delays of up to 30 minutes at peak times. Parents taking children to schools were among the worst hit. But they were not alone, staff going to work in the Denaby area found themselves late for work.”
A spokeswoman for the National Grid said the scheme is costing about £200,000 to complete and the temporary traffic lights will be removed before the end of the month.
She said: “To carry out the work safely we have had to install temporary traffic lights. The traffic lights are being manually controlled between 7am and 7pm to try and keep traffic flowing. They will be removed as soon as we complete this section, which is expected to be finished by February 21.“
