A four-month programme of work which will improve safety at Lower Lodge is scheduled to start on 16 January to enable completion in time to meet increased traffic volumes during the summer.
The £3.6 million scheme will involve reinforcing the carriageway, construction of a new retaining wall, the installation of vehicle restraint barriers, drainage improvements, resurfacing and associated road marking, and throughout the work diversion routes will be clearly signed.
Nick Reed, area team leader for Highways England, said:
We have planned the work so it has the least impact on local communities, ensuring it coincides with the quietest period on the roads.
We have liaised with businesses along the route and access will be maintained throughout the project, and will be clearly shown on the diversion route signing.
Some overnight road closures and daytime diversions for westbound traffic will be needed to carry out this work, we apologise in advance for any inconvenience but we will keep any disruption to an absolute minimum.
Night-time closures will be introduced from 16 January, with signed diversion routes between the Twelvewoods and Turfdown roundabouts, while 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 daytime closure, 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.
Bruce Robertson, owner and chairman of Trago, said:
It will be business as usual during these essential works and Highways England have undertaken that diversions will be clearly posted throughout the affected routes, allowing the best possible access to Trago at all times.
The new year safety work is supported by Cornwall Council and Jeremy Edwards, from the council’s Transportation Service, said:
We are pleased that Highways England is investing in the maintenance of this key strategic route.
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 6am on Sunday 15 January. Diversion routes will be clearly signed.
