Highways England have announced a programme of works to resurface the A34-M4 roundabout and other sections of the A34 between the A4 Speen exit and Chieveley.
The series of northbound road closures on the A339, A34 and north slip from the M4 onto the A34 will come into effect for 20 nights between now and the middle of March. Closures will be between 10pm and 6am with appropriate diversions in place.
A similar scheme of work, which will close southbound roads, is planned but no dates have been announced yet.
