From Monday, 10 June traffic travelling along the A390 in Truro will be diverted from the existing section of road at Penstraze through the north side of the new West Langarth roundabout.

Temporary traffic lights will be in place between 7pm on Monday evening (10 June ) until 6 am on Tuesday morning ( 11 June) to enable the changes to take place.  Once the new layout is in place, the traffic lights will be removed and traffic flow will continue along the new route as normal. 

The change to the 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.

Please see the diagram and image below for more detail. 

Anyone with queries or concerns should call 0300 1234 222 or email CORMAC at [email protected]
