Two weeks of major disruption on one of the main routes out of Helston is to begin on Tuesday.
Traffic travelling the B3297 between Helston and Redruth will be affected by 14 days of road closures.
Stop-go boards will be in place first, on Tuesday, while siding works are carried out.
The full road closure then kicks in on Wednesday, in staggered sections of the road.
It will be in place between 9.30am and 4.30pm each day, according to Wendron Parish Council, which has released further details.
Helston to Wendron will be the first section to be closed, this Wednesday and Thursday.
This will be followed by Wendron to Trenear from Friday until Tuesday, January 28.
The closure will be in place between Pencoys and Nine Maidens for two days from Wednesday, January 29, followed by Four Lanes to Redruth from Friday, January 31 to the following Tuesday, February 4.
The closures are to allow patching works to take place on the surface of the road.
Traffic marshals will be in position throughout, to help road users.
Access will be maintained for emergency vehicles, deliveries and those that live within the closed section.
However, it is likely to be a major headache for those that use the road to get to work each day, access the A30 and parents of pupils at Wendron Primary School and Nine Maidens Academy, with alternative routes likely to be especially busy at rush hour and school pick up times.
