A30 Temple to
Higher Carblake
improvement scheme

Journey Impact

Unfortunately building a new road alongside a ‘live’ carriageway creates its own problems; therefore we cannot avoid the need for traffic management. This will be as much to protect your safety as that of the workforce.


We often get asked why the roadworks are so long given the actual construction is just over 2.5 miles. The length of the lead-in at either end of the works is guided by traffic management regulations. As a result of the narrow ‘live’ lanes a 40mph speed limit is required throughout the scheme for everyone’s safety. Average speed cameras strictly enforce the speed limit at all times. We also have a 24/7 recovery service to handle any situation within the roadworks.

Will there be diversions

Certain elements of the work unfortunately require the A30 to be closed in one or both directions for works to take place e.g. the lifting of bridge beams or changing the traffic management. Rest assured all such closures will take place at night to minimise disruption to the travelling public and local residents alike.

Advance warning of any closures will be given on information signs situated alongside the roadworks. Notices will also be made available via local newspapers, local radio and Cornwall Council’s own website. Appropriate traffic diversion signage will be displayed throughout the diversion routes for the duration of the closure.  At times we will need to close off side roads at their junctions with the A30 to allow for construction works. Local signage will advise drivers of closures ahead and giving alternative routes should they be required.  Advance warning of planned closures will be displayed in ‘Updates’ on the front page of the website.  As we approach the final phase of works it is anticipated that there will not be many further closures in 2017.
