LANES have been temporarily narrowed on the M1 roundabout at Dodworth.

The modified layout allows vehicles to use two narrowed outer lanes while highway operatives work safely inside a cordoned zone around the hub of the roundabout.

The narrow lanes will remain in operation until May, when the project is scheduled to reach completion.

The alterations are part of works to improve capacity at the intersection by installing traffic signs on the approach roads to the roundabout.
