Works will take place to level the carriageway and switch west bound traffic onto the new road surface.

For anyone not wishing to use the M1 when the A421 is closed, a diversion route along the A422 will be available instead.

A council spokesman said: “Every effort has been made to reduce disruption to road users and the work will be carried out as quickly as possible.”

But he warned: “Weather conditions or incidents on the road may affect these planned works.”
