Junction improvements are being made at locations around Sheffield.
The second phase of a scheme to increase capacity at Moore Street roundabout, on the inner ring road, begins on Monday, with three narrow lanes on the Moore Street approach widened and a bus lane removed.
Work takes place in off-peak hours and follows a similar project to widen the approach from Hanover Way.
A scheme begins the same day at the Northfield Road and Heavygate Road junction, Walkley, to alter the junction and install a pedestrian crossing. Improved crossing facilities, humps and better street lighting are being installed on Dyche Road, Jordanthorpe.
