Drivers are advised to avoid a road as works will cause a closure for one day on June 14.
Newbridge Road in Ambergate will be closed between the A6 Derby Road junction and Toadmore Lane to allow inspections of the railway bridge.
Motorists should take an alternative route via the A6 Derby Road, A610 Ripley Road / Riversdale, New Road, Crich Lane, Newbridge Road and vice versa.
Access will be maintained, whenever reasonably possible, on the affected length of road, which will re-open as soon as the work is finished. This may be earlier than advertised, but should be by the following day, June 15.
Derbyshire County Council apologises for any inconvenience caused while work takes place. Anyone needing further information should ring Call Derbyshire on 01629 533190.
