Motorists are being warned about road works that started this week and are planned for the next five months.
The work involves removing overhead cables and placing them underground.
It is being carried out by Western Power Distribution, on behalf of Morrisons Utilities, and will affect Nottingham Road, Annesley Road, Baker Street, High Street, Station street and Linby Road.
Various temporary traffic lights will be in place - some controlled manually during peak times- while there will be diversions to help ease congestion.
The work will be done in six sections, with work already beginning on Annesley Road. After that, work will start on Linby Road to Station Road on 9th June, set for completion on 27th June.
