Work to ease congestion on the A329M slip roads will continue next week.
The scheme to widen the slip roads at the junctions with the M4 will require the roads to be closed overnight from Monday (26).
The slip roads on the Reading-bound carriageway will be closed between 9pm and 6am from Monday for five nights.
Highways England said that a clearly signed diversion will be in place via the A329M Wokingham-bound carriageway and the Coppid Beech roundabout.
Work is due to be complete by the end of October.
