Motorists will be forced to endure delays on the A339 next week as planned lane closures come into effect.
The closures are expected to take place as part of the continuing improvement works along the busy stretch south of the Robin Hood roundabout.
Lane closures will be put in place while the handrails on the bridge over the River Kennet adjacent to Newbury Library are being refurbished.
West Berkshire Council say the handrail removal works will begin on the northbound carriageway on Sunday evening (July 3) and will continue until Friday with off-peak lane closures required throughout the week.
The works, which began in February, have seen lanes narrowed between the Robin Hood roundabout and the Bear Lane roundabout and a temporary 30mph speed limit introduced.
The project will eventually see the dual carriageway south of the Robin Hood roundabout widened before a new junction is installed leading on to the London Road Industrial Estate (LRIE).
The roadworks are expected to last until the end of the year paving the way for the redevelopment of the LRIE.
