Motorists are being warned to expect delays on the A617 Hasland by-pass while roadworks are carried out.
Preparatory work to surface dress the five mile stretch of road between Horns Bridge, Chesterfield, and junction 29 of the M1 is expected to start on Monday, July 10.
Both directions of the by-pass will be closed overnight weekdays between 7pm and 5am from Monday, July 10 to Friday, July 14.
On Saturday July 15, the eastbound carriageway will close from 5am to 11pm for surface dressing.
On Sunday, July 16 the westbound carriageway will close from 5am to 11pm, again for surface dressing.
Surface dressing seals the road to prevent water getting in and cracks and potholes forming.
First the road is patched, if necessary. A layer of bitumen is then added to act as ‘glue’ before the road is topped with chippings. Driving over the road helps to bed in the chippings.
Surface dressing can only be carried out in the summer as the warmer weather is needed to help the chippings bind to the bitumen.
If bad weather prevents work being carried out on 15 and 16 July it will be postponed until the following weekend.
Work to sweep the road of loose chippings and replace road markings is scheduled to start on Monday, July 17.
Both directions of the by-pass will be closed overnight weekdays between 7pm and 5am from Monda, July 17 to Sunday, July 30.
Councillor Simon Spencer, Derbyshire County Council’s cabinet member for highways, transport and infrastructure,
said: “We appreciate that any road works can cause inconvenience to motorists but these repairs are essential to keep the by-pass in a safe and reliable condition.
“We have tried to keep disruption to a minimum by doing these improvements overnight and at weekends to avoid peak commuting times and we will endeavour to complete the work as quickly as possible, which may be earlier than advertised.”
Signed diversions will be in place during closures. The diversion is the A61 Horns Bridge to Clay Cross, Harris Way, Bridge Street, Furnace Hill Road, the A6175 Market Street to the A6175 Heath Road and the A617 Heath Roundabout, and vice versa. Other local roads will be useable by light traffic.
