WORKS starts on Monday on the latest phase of a scheme designed to ease congestion at the Moore Street roundabout on the edge of Sheffield city centre.
The road will be widened on Charter Row approaching the roundabout so that three full lanes are created.
In addition the outbound bus lane near the Wickes DIY store will be removed and lane markings will change, which the council says should improve the use of all the lanes on the roundabout, especially for larger vehicles.
The way the roundabout looks will not fundamentally change but drivers heading towards Ecclesall Road will no longer be able to use the inside lane on the approach. The width of the central reserve on Charter Row will be removed.
Construction will take up to seven weeks and will involve lane closures between 9.30 am and 3.30pm Monday to Friday to avoid disruption to motorists at peak times.
The roundabout has limited capacity because approach lanes on Charter Row are too narrow, meaning that larger vehicles regularly block two lanes. Lane markings also do not reflect current traffic flows and turning movements.
Council transport cabinet member Ian Auckland said: “Small improvements to capacity at the junction of the roundabout should contribute to bigger improvements for motorists.
“By widening the lanes vehicles will be able to make better use of the roundabout, helping getting through Moore Street roundabout faster.”
