TEMPORARY traffic lights on the slip road between the A6 and St Alkmund's Way in Derby will be switched on at 10am today.
The eastbound carriageway will also be reduced to one lane as part of a £1.2 million six-month programme of maintenance to repair three bridges and lighting.
Traffic delays are expected in the area during the morning and evening rush hours until July.
