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.

A30 Junctions


Summer Period – Q&A’s

Three-lane Running

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 – Why are you implementing three-lane working for the summer period?

A – To help alleviate some of the expected congestion during the busy summer period from Friday 22 July until Sunday 4 September two lanes are planned for eastbound traffic (out of Cornwall) and a single lane running westbound (into Cornwall). This improvement will help ease congestion for eastbound traffic which historically suffers the worst delays as a result of checkout times at holiday destinations.

Q – What about westbound A30 traffic, won’t that suffer delays as well?

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 traffic restrictions as a result of the 3 lane working?

A – There will be restrictions imposed as a result of the temporary 3 lane working. Safety is paramount for both the road user and the workforce. As the three-lane working will be a new innovation to the current single lane working a total ‘No Right Turn’ ban will be imposed throughout the duration of the six week scheme.  This will mean a ban on right-turns on all side roads into or out of the respective junction.  Diversion routes for all junctions are well signed.  The rationale behind the decision is that it is deemed unsafe to wait in the two lane section to turn right and likewise to cross two lanes of moving traffic if turning across eastbound traffic.

Q – Are left turns going to be allowed?

A – Yes. Left-turns into and out will be allowed at all junctions that are currently open.

Q – What about lorries travelling east through the roadworks?

A – Lorries will be confined to the inside lane (lane 1) whilst cars and light vans can use either lane. This is for road safety purposes.

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 – What is the next phase of construction following the three-lane working?

A – Following the three-lane working the road layout will revert to the contraflow working we had just prior to the change for summer. This will enable major carriageway and bridge works to continue and to construct the link roads to the three new bridges.   

Q – When will the bridges be open?

A – With a fair weather scenario we should see Preeze Cross Bridge 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.

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.

    Kier Works/Travel Update – 28 July 2016

    A30 – Advance notice of ‘Four Winds’ junction closure

    Trewardale junction now open for all Blisland/St Breward traffic.

    Please be advised that the junction at ‘Four Winds’ with the A30 will be closed to all traffic from 09.30am Monday 1st August 2016 until works are completed by the end of September.  Alternative arrangements will be made for local residents.  The works involve constructing new drainage and carriageway improvements including the widening of the junction with the A30.

    To facilitate the Four Winds closure access for Blisland/St Breward through traffic can be gained via the Trewardale junction which is now open.  For those not conversant with the location of Trewardale junction it is (Junction 1.) on our site plan viewed from the front page of our website www.kier-a30cornwall.co.uk

    As there is already a ‘no right-turn’ prohibition for westbound A30 traffic at Four Winds the diversion route will remain the same – via the Callywith off-ramp at Bodmin and return east on the A30.  Trewardale junction will be the next exit following the newly opened Helland junction.  Access to the A30 can be made from the start of the diversion route at White Cross crossroads, west to the Trewardale junction where a left turn only is available onto the A30.

    If you have any concerns please contact Mick Martin – Kier Public Liaison Officer on 07790 560 809 or email michael.martin@kier.co.uk

    Kier Works/Travel Update – 22 July 2016

    Cornwall Council Press Release

    More than one million people set to benefit from extra lane on notorious A30 bottleneck

    22 July 2016

    A second lane will be in place on the A30 eastbound between Temple and Higher Carblake this summer – doubling the capacity on the notorious bottleneck.

    With work to build the dual carriageway on schedule for completion next Spring, the construction team from contractors Kier have been working around the clock to meet the aim of having two lanes in place eastbound in time for the busy summer holiday season.

    More than one million people are set to benefit from the opening of the second lane, which will be in open between Friday 22 July and Sunday 4 September.

    “This is very welcome news for the tourist industry in Cornwall and visitors joining us this summer,” said Lord St Levan, Chairman of Visit Cornwall. “The opening of a second lane eastbound means after enjoying all that Cornwall has to offer, visitors won’t have their memories diminished by queuing at this well-known bottleneck.”

    “The dualling at Temple hasn’t been without unforeseen complications – many of which won’t have been discernable to the public. We’re thrilled therefore that Cornwall Council has succeeded in opening another lane just in time for the summer season, and wholeheartedly support its decision to make the additional lane outbound to avoid the lasting memory of visitors leaving Cornwall to be one of severe traffic congestion,” said Mel Colton-Dyer, Head of Business Connections and Skills at Cornwall Council.

    “On behalf of the Cornwall Business Partnership, I would like to say that we are delighted to see this further key step in achieving the vital infrastructure that Cornwall has needed for so long and Cornwall Council and Kier are to be congratulated on their commitment to its timely delivery,” said Thelma Sorensen, Chairman of the Cornwall Business Partnership.

    Ann Vandermeulen from the Federation of Small Businesses, said: “Road improvements in our rural county are a very big priority for everyone and in particular small businesses. From fresh food producers who need to move their goods quickly to their customers to service providers like plumbers, electricians and builders to our tourism customers and anyone who needs to be able to move unhindered through our county, this is one project that is going to make a massive difference to all.  As you can’t make an omelette without breaking eggs, so any major works do cause temporary problems while they are under way. Not ideal but has been unavoidably necessary with the end result culminating in a permanent improvement. Therefore it is with real delight and relief that we welcome the opening of this road over the peak season.”

    Steve Wood, Projects Team Leader from Cornwall Council, said: “We know how important this route is to local people, visitors and businesses and are pleased to have been able to achieve a second lane running eastbound in time for peak season. “We have also been working with our colleagues at Highways England to ensure people travelling westbound can be armed with as much information as possible both before setting off and while on their way to Cornwall.”

    Since construction on the dual carriageway began last year, contractors Kier have cut around 70,000 cubic metres of earth, laid around 3,000 cubic metres of concrete and installed 10,000 linear metres of drainage.

    Jamie Bee, Project Manager for Kier, said: “Despite the challenges thrown at us from Bodmin Moor, the Kier team and our supply chain have worked extremely hard, seven days a week, including a five week programme of permanent night-shifts to increase the capacity of the A30 for the summer holiday period. This intensive programme period has seen us complete the bridge decks over the road and approximately 3.5km of new carriageway. It has been a huge effort from all those involved and I am very pleased that we have managed to achieve this significant milestone.”

    Councillor Chris Batters, Cornwall Council Local Member for Lanivet and Blisland, said: “As someone who has regularly driven the A30 Launceston to Bodmin road since the mid-sixties, I’ve witnessed it’s improvement over those years, but this final stretch of dualling is going to allow motorists to enjoy their drive across the beautiful Bodmin Moors both when entering and exiting Cornwall, and remove much frustration experienced over the years, and more importantly make the road a much safer route.”

    Henry Kendall, who lives in Blisland, added “The three-lanes at Temple will be a fantastic bonus for all local residents on both sides of the A30 who have had to endure the inconvenience of traffic using our narrow country lanes trying to avoid tailbacks on the A30.  It is a magnificent achievement to have reached this key date in the construction of the new road in just 15 months.”

    Nick Reed from Highways England, said: “We continue to work closely with Cornwall Council to deliver this project and ensure that disruption to motorists in kept to a minimum.”

    The A30 Temple to Higher Carblake dual carriageway improvement scheme is being led by Cornwall Council in partnership with the Department for Transport and Highways England.
    People due to travel westbound on the A30 past the roadworks are being advised to plan ahead where possible. Advice on where to go for live traffic information, as well as alternative routes and peak travel times, are available on the Council’s website www.cornwall.gov.uk/a30Temple
