We're extending the two-lane section on St Augustines Road, Birdholme, on its approach to the junction with the A61 Derby Road, by an extra 100 metres.
St Augustines Road, between the junctions with St Augustines Crescent and the A61, will also be widened.
The three sets of traffic signals at the junction of St Augustines Road and the A61 are also being upgraded with more up-to-date signals.
Work is expected to start on Monday 28 January and is estimated to take until Friday 5 April 2019.
During the two-lane extension and road widening work St Augustines Road will be one-way for traffic travelling uphill (westbound) from the junction with the A61.
Signposted diversions will be in place for traffic travelling downhill (eastbound) wanting to join the A61. For light traffic, the alternative route is along Boythorpe Road, Park Road, Baden Powell Road and back on to the A61.
Other traffic will be diverted along Boythorpe Road, the A619 West Bars, Markham Road, the A617 Lordsmill Street and then rejoin the A61.
Once this work is finished, St Augustines Road between the junctions of St Augustines Crescent and the A61 will be closed completely while the traffic lights are replaced.
A new pedestrian crossing will also be installed where the A61 meets St Augustines Road.
The diversionary routes are the same as before but this time for traffic travelling in both directions.
Temporary traffic lights will be in place while the permanent signals are installed.
Our Cabinet Member for Highways, Transport and Infrastructure, Councillor Simon Spencer, said:
“I appreciate that these works may cause some inconvenience but they are necessary improvements to upgrade out of date traffic signals. Extending the two-lane section will also help to ease the problem of traffic backing up as it waits to join the main road.”
Councillor Spencer added:
“While the road closure is in place work to repair pavements, damaged by flooding, will also take place.”
