Traffic on the A390 at Penstraze in Truro will be diverted from Monday, from the existing section of road through the north side of the new West Langarth roundabout.
Temporary traffic lights will be in place between 7pm on Monday evening until 6am the following morning to enable changes to take place. Once the lights have been removed, traffic flow will continue along the new route.
The change in road layout is part of the Northern Access Road scheme and will enable CORMAC to link sections of shared-use path with the Saints Trail which was completed earlier this year.
