Islanders are being warned to expect days of disruption as Southern Water works on Staplers Road resume next week.
The Isle of Wight Council says a £400,000 scheme to safeguard water supplies on the busy route will resume on Monday (23).
The local authority and Island Roads say they hope it will be complete before St Mary’s roundabout work begins the following week (30).
The latest phase follows work which took place in April and May, as previously reported by Isle of Wight Radio.
It is expected to take five days and will see temporary traffic lights installed. These lights will be manually controlled during morning and evening peak hours to aid the flow of traffic.
The junction of Staplers Road and Mayfield Drive will be shut.
Southern Water project manager, Peter Simmons, said local residents had been informed of the latest works which were designed to “safeguard supplies for the community effectively into the future.”
“We appreciate these works can cause an inconvenience, and so we thank everyone for their patience as we carry out this final phase of work.”
Southern Water says final surfacing work at Staplers will be completed later in the autumn.
