Dorset Highways has been contracted by SSE to carry out remedial surfacing where electrical cabling work was completed last year.
The one-mile-long trench between Ferry Bridge and Hamm Roundabout failed the ‘rolling straight edge’ test after the works, confirming that the surface has been left irregular and bumpy, and is not compliant with specification.
The full width of the southbound lane of Portland Beach Road, from Ferry Bridge to Hamm Roundabout, will be resurfaced over three nights.
Two-way temporary traffic signals will be in place overnight between 9pm and 6am with a convoy vehicle leading traffic slowly past the works area.
The work will take three nights, with the first night on Friday 19 July into Saturday morning and returning after the weekend for two nights on Monday 22 and Tuesday 23 July with the work completed in the early hours of Wednesday morning.
Kevin Cheleda, Dorset Council Traffic Team Leader, said: “We inspect utility/private contractor work at three separate stages – during the work, six months after completion and around two years after completion.
“SSE has agreed to resurface the full width of the southbound carriageway for the length of the trench as this will ensure the same issue doesn’t reoccur.”
