NEW traffic lights will be installed at junction 37 at a cost of £2 million to resolve the road's congestion issues.
Cabinet members approved the plans on Wednesday in a bid to reduce traffic and potentially attract new businesses to the area.
The works are part of a wider £15.7m plan which is to be invested into Barnsley's road network.
The Department for Transport has pledged £1.4m for the project, with the £600,000 shortfall being made up by a grant from the European Regional Development Fund.
Coun Roy Miller said: "Making sure we have the right transport infrastructure in place is crucial in making sure Barnsley can facilitate growth."
The scheme is similar to the project at Birdwell on junction 36 of the M1, and involves lights being placed at all eight entrances and exits of the roundabout.
