A30 Temple to
Higher Carblake
improvement scheme

2016-05-31 - A30 Temple Scheme - map only (2)

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 Spring 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.

Where’s the Bear 2016

Following on from the success of the 2014 Where’s the Bear Challenge which raised and incredible £32,000 for the Kier Foundation.

In this Olympic year we aim to beat that record. The team have challenged themselves to travel over 1,000 miles across the UK taking in all of Kier’s sites throughout the country whilst transporting the Kier mascot bear in non-motorised transport.

Each site is aiming to raise £500 in sponsorship and donations which will then be distributed to local and national charitable causes, community projects and Kier’s charitable partner.

Please click on the  “Where’s the Bear” Banner or click here to follow the link and make your worthwhile donation for this fabulous cause. Please let us know that your donation has come from the Kier’s “A30 Temple to Higher Carblake Road Improvement Scheme”

Thank you very much for all your donations

    Kier Travel Update – 22 September 2016

    A30 – Advance Notice – No Right-turn Temple Fishery Layby

    Pease be advised of a restriction on right turning traffic at Temple Fishery layby; this includes no right-turn into the layby for eastbound A30 traffic and no right-turn from the layby onto the A30 eastbound heading towards Launceston.

    A ‘No Right-Turn’ prohibition will be introduced at Temple Fishery layby following a new traffic management scheme being implemented on the evening of Tuesday 26th September 2016.  Works will be carried out under traffic light control.

    The prohibition will remain until all works are completed by late November / December.

    The change of lanes will enable essential works to be carried out for drainage and carriageway work. The lane changes will mean eastbound A30 traffic will be diverted onto the recently completed eastbound carriageway utilising lane 2 (outside lane). The westbound A30 traffic will continue using the existing westbound carriageway but only in lane 2 (outside lane). Right-turns are not available due to the new ‘dual carriageway’ working.

    The advisory diversion routes for residents and visitors to Temple are as follows:-

    A30 – travelling east requiring right-turn at Temple Fishery layby – continue east on A30 towards Launceston following diversion signs – leave A30 at Bolventor and return westbound – take left turn at cutting on A30 at Brockabarrow Common just after Colliford Lake junction.

    A30 – requiring right-turn at Temple Fishery layby – drivers requiring to travel east on the A30 towards Launceston – take lane out of Temple leading to Brockabarrow Common cutting on A30 – travel west for short distance to Hawks Tor Gap – return on A30 east towards Launceston.

    A30 – alternative route if requiring right-turn at Temple Fishery layby – turn left at layby – travel west towards Bodmin – leave A30 at Bodmin off-slip – return via A30 eastbound towards Launceston.

    Kier apologise for the inconvenience these diversions may cause. If you have any queries regarding these latest works then please contact Mick Martin via email michael.martin@kier.co.uk

    A30 – Post Summer Travel Advice

    Now that we are back with two lanes running (single lane in either direction) following the busy summer period there are still ways to avoid the traffic congestion that can still occur during the autumn period.

    Q – How can you avoid possible delays at Temple?

    A –Whether you are visiting or leaving Cornwall there are a number of steps you can take to avoid delays. Firstly and simply please try and plan your journey to avoid peak periods. It is appreciated this is not always possible but it will enable you to avoid the frustration of sitting in heavy traffic. Planning a different route altogether should be considered prior to starting out on your journey (such as A30 westbound, or A39/A395 eastbound).  But please, please do not use your SatNav if you are in the vicinity of the works.  It is almost impossible to cross Bodmin Moor without travelling along unsuitable narrow lanes with no passing places and no access back onto the A30; you will probably end up at the back of the queue you tried to avoid!

    Q – When are the peak periods?

    A – Westbound A30 – Fridays between 12noon and 6pm and Saturdays from 8am until 4pm. Eastbound A30 – Fridays 10am to 4pm; Saturdays and Sundays 10.am to 4pm – Monday mornings can also be busy during the height of the summer season.  See below for information concerning the two lanes operational eastbound during the peak summer period.

    Q – Where can I find traffic information easily?

    A – With the use of mobile devices (not whilst driving!) it is possible to get up to the minute traffic news on www.mydrive.tomtom.com/en_gb/ or www.trafficengland.com You can also check out local traffic reports, on Twitter @HighwaysSWEST @DC_Police @BBCTravelSW or the BBC Cornwall website www.bbc.co.uk/travel/cornwall/incidents/road

    Q – What about eastbound A30 traffic?

    A – Historically the eastbound suffers the worst delays as a result of checkout times at holiday destinations further down the county. Please try and stagger your journey times and avoid the busy times mentioned above. Leaving extra early really is a time saver; you can then take a break further up country when you have avoided the pinch-point at Temple.

    Q – What about westbound A30 traffic?

    A – Visitors to Cornwall have far greater choices to adjust their timing and or route according to any delays foreseen. Drivers will be better informed as a result of electronic variable message signs (VMS) for drivers travelling down the M5 west into Cornwall.   Mobile VMS signing will also be available on the A30 prior to Temple advising drivers of any delays, allowing drivers to take alternative routes if appropriate.  

    Q. – What about cyclists riding through the roadworks? 

    A.– For their own safety there is a total prohibition on cyclists riding through the roadworks.  It is not safe for cyclists as the lanes through the works are narrow, hence the 40mph reduced speed limit.  As a result of the prohibition a well signed diversion route is available for all cyclists:-

    For cyclists travelling east on the A30 they should leave at the Bodmin off-ramp at Carminow Cross and follow the clearly marked cycle route via Fletchers Bridge, Mount and Bolventor.

    For cyclists travelling west on the A30 they should leave at the Colliford Lake turn-off and follow the clearly marked cycle route via Mount and Fletchers Bridge.

    Q – Will the 40mph speed limit still apply?

    A – Most certainly the 40mph speed limit will continue to be enforced with the use of average speed monitoring cameras. Please remember enforcement of the speed limit is not just from the beginning to the end of the roadworks, it can be between two sets of cameras.

    Q – Why have there been so many prosecutions for speed violations?

    A – The advice from the Peninsular Road Safety Partnership who run the traffic scheme is that, to avoid getting caught the most important fact to remember is that the moment you pass the first large 40mph signs the speed limit becomes enforceable and remains so throughout the entire length of the roadworks – The speed limit is enforced irrespective of the number of lanes, road classification, traffic flow, visible workforce, day of the week, time of day or weather conditions.

    Q – When will the bridges be open?

    A – With a fair weather scenario we should see Preeze Cross Bridge (central of the three bridges) completed and open to traffic by the end of the year. Cardinham and Temple Tor Bridges should be completed by early next year 2017.             

    Q – When will the dual carriageway be in full operation?

    A – The dual carriageway should be fully operational from March 2017; of course this is again subject to the vagaries of the weather throughout the winter period.
