A30 Temple to
Higher Carblake
improvement scheme

Scheme Overview

The current single carriageway of the A30 between Temple and Higher Carblake is the only section of single carriageway between leaving Scotland and reaching Temple. This 4.5km section of road is being improved to dual carriageway standard for the entire length which will negate regular traffic congestion in the area.


Link to Cornwall Council video release 22.03.16

Work started in June 2015 and is due for completion in July 2017.

We are dualling the single carriageway on the A30 between Temple and Higher Carblake, just east of Bodmin. The length of road involved is 2.8 miles (4.5km). Three busy road junctions will be replaced by three overbridges; one bridge at either end at Cardinham and Temple junctions and one relatively centre at Preeze Cross/Four Winds. The dual carriageway is being constructed literally alongside the existing road and traffic management is a key element of the project.

Impact on Your Journey

Regular users of the road will know that there has always been considerable congestion on Fridays through to Mondays, Bank Holidays and of course during the summer holiday period for the past decade. However this should all change when the works are completed.

There is a strictly enforced 40 mph average speed restriction throughout the works as a result of the narrow lanes and for the safety of all road users.

It may be interesting to note that the speed restriction should only add a few minutes to your total journey time.


Benefits of the scheme

The scheme will relieve congestion and improve journey times – it will also attract business growth and inward investment to Cornwall by improving links with the rest of England. The new dual carriageway will also be much safer than the single carriageway as a result of the three overbridges.

There will also be job opportunities for local individuals and businesses for the duration of the scheme.

    Kier Travel & Works Update – 14 June 2017

    A30 Carriageway Switch

    A30 traffic has now been switched to running on the Westbound Carriageway.  This has been done to allow us to finally complete the Eastbound carriageway works.

    Unfortunately this may now cause some minor interruptions to your day to day travel; however this is only for a short period of time until we get the full dual carriageway running for 14th July.

    Safety of the general public and our workforce is of paramount importance and as such right turns on and off side roads across the imposing traffic is not permitted as directed by signage at the side road junctions.

    Traffic heading in a westerly direction if they need to turn right they will have to come off at the Bodmin junction slip road and return in an easterly direction then being allowed to turn left in to your destination.  Likewise traffic heading in an easterly direction and you need to turn right, you will need to come off at Jamaica Inn slip road or Colliford Lake junction and return in a westerly direction which will then allow you to turn left at your destination.

    We continue to have at short notice wide loads which are required to pass through our works which do cause short term disruptions as we have to close one lane as the load passes through, this is unfortunately beyond our control.

    The current good weather we are experiencing is helping us with our work activities and hope this will continue into the ensuing summer months.

    We thank you for your patience during these completion activities which will allow the dual carriageway to be fully opened for the forthcoming school holidays.

    Kier Travel and Works Update – 2 June 2017

    Airfield Road Access to A30 – Temporary Closure

    Please be advised Airfield Road junction with the A30 will be closed between Wednesday 7th (afternoon); Thursday 8th, Friday 9th June and Saturday 10th June inclusive.

    Access to the A30 is not affected as drivers can still use Lidcutt Road at all times. Closure notices of Airfield Road will be displayed when appropriate.

    Work involves laying the final surface course of asphalt on the westbound carriageway across the mouth of Airfield Road. Unfortunately due to the nature of the works involved we cannot ascertain for what period of time the junction is likely to be closed. Please rest assured the junction will be opened if constraints allow.

    Please note: The current temporary access via Cardinham Gap (for westbound A30 traffic) at the junction will also need to be closed due to the work across the junction.

    The local diversion for Airfield Road will be via Lidcutt Road as per previous Airfield Road closures; this is only provided the gap is not closed. When the Cardinham Gap is closed the diversion for traffic will be via Callywith Gate; to Carminow Cross roundabout; left-turn onto A38 and left again at Crematorium; continue via Fletcher’s Bridge to Cardinham returning to Airfield Road if required.

    Airfield Road will only be closed at the immediate junction with the A30; access will still be available to Bodmin Airfield and its environs plus Kier site compound.

    Kier Works Update – 31 May 2017

    A30 – Lane Change – Pounds Conce

    Please be advised there will be a small lane change at Pounds Conce (dip in road approximately centre of works) on the evening of Friday 2nd June 2017 when traffic will revert back to the eastbound carriageway. This will mean the entire length of traffic management through the works will be running in the eastbound carriageway. This will enable the final surface course to be laid on whole westbound carriageway. When completed traffic will revert back to the entire westbound carriageway to enable remedial works and the final surface course to be laid on the eastbound carriageway.

    Please note: This is part of the final phase of carriageway work prior to the opening of the dual carriageway. The work is delayed to ensure heavy works plant does not use the road following the final surface being laid.

    Any queries please contact the Kier answerphone service line on 07779 439 637 or via email a30bodmin@kier.co.uk
