A new automatic detection system to warn drivers of queues ahead will be installed on the A30 at Shallowater between Bodmin and Launceston.
The new safety warning system replaces a manually controlled sign and will help reduce the risk of rear end collisions caused by restricted visibility.
Highways Agency Project Manager, Nigel Dyson, said: “Currently, when a queue builds-up, we have to rely on our patrols or members of the public to let us know; we then activate the queue warning signs, and all this can take time. The new signing system will instantly warn drivers of queues ahead, improving safety.”
Work is due to start on Monday 12 January and should be completed by Easter. The £420,000 project will involve installation of detection loops, cabling and electronic equipment and will affect a three mile stretch of the westbound carriageway.
Most of the work will be carried out under lane closures, but for the first three weeks the westbound carriageway will be closed between Colliford Lake junction until St Breward Crossroads, and a contraflow system will be in place on the eastbound carriageway. The Temple Junction and St Breward Crossroads will also be closed. A clearly signed diversion route will be in operation for local traffic. Temple traffic will exit and enter the A30 via the Temple Fisheries junction. Access to and from the A30 for the Blisland and Bradford areas will be via Blisland Junction.
A temporary 50mph limit will be in place during the works, and drivers are reminded to obey the speed limit for their own safety and that of the workforce.
