THE A39 between Wainhouse Corner to Treskinnick Cross is set to be closed overnights until Saturday, March 9.
The overnight closures, in place from 7pm until 6am, was originally scheduled to take place from February 14.
Its closure is to facilitate necessary work and maintenance of the road, with Cornwall Council asking residents to ‘plan journeys accordingly’.
A spokesperson said: “As part of our highways maintenance work, an overnight road closure will be in place on the A39 between the B3262 and Treskinnick Cross while resurfacing work is carried out at Wainhouse Corner.
“The work will take place between the hours of 7pm and 6am. Outside of these times, the road will be open as normal. We need to implement these measures to give our teams a safe working zone and protect road users while the work is carried out.
“We know that noise associated with night-time working can cause disruption to residents and we understand this can be frustrating. Please be assured we aim to complete the noisiest operations as early as possible and will try and minimise the impact should the works overrun due to unforeseen circumstances.
“All through traffic will need to follow the diversions in place.”
