The £3.6 million scheme will involve reinforcing the carriageway, construction of a new retaining wall, the installation of vehicle restraint barrier, drainage improvements, resurfacing and associated road markings, and throughout the work diversion routes will be clearly signed.
The work has been planned carefully to ensure it coincides with the quietest period on the roads and causes the least possible impact to local communities. Access for local residents and to businesses along the route will be retained throughout the works.
All works will be completed before the busy summer holiday period.
Night-time closures will be introduced from 16 January between 8.30pm and 6am, with signed diversion routes between the Twelvewoods and Turfdown roundabouts, whilst from 30 January a 24-hour one-way system will operate between the Halfway House and Trago Mills.
Eastbound traffic will be unaffected during the operation of the one-way system, with westbound traffic diverted via the A390 and access to Trago Mills maintained throughout. For safety reasons, a 30mph speed limit will also be introduced through the works at the end of January.
All traffic management will be removed for the Easter Holiday weekend, with the 30mph speed limit remaining for safety reasons. Overnight closures will resume after the Easter Holiday weekend until the completion of work in May.
As a precursor to the work, a drainage culvert will also be repaired near Lower Lodge, which will see the A38 closed overnight from 6.30pm on Saturday 14 January to 9.30am on Sunday 15 January. Diversion routes will be clearly signed.
We apologise in advance for any inconvenience but we will keep any disruption to an absolute minimum.
