• 07 March 2025

  We’ve reopened part of the old A30 as the B3288

  Last weekend we reopened the old A30 as the B3288 between Chybucca and Boxheater (near Zelah). This marks a significant step in completing the A30 Chiverton to Carland Cross project.

  Going forward, drivers will be able to use the old Zelah bypass as a link between local roads and the A30 dual carriageway, reducing traffic levels in the village. 

  B3284 south closure will continue during March

  The B3284 south of the new A30 is now closed and is scheduled to reopen on 24 March. Traffic is being diverted via Allet Lane to join the old A30 and then on to Chybucca. There will a temporary 30mph speed limit in place. Please observe this, the local diversion signage and allow additional time for your journeys.

  Old A30 closure by Carland Cross Junction

  From 03 March, we closed the section of the realigned old A30 between Carland Cross and Boxheater. The closure will be for up to 5 weeks in order to complete it and then reopen it as a new section of the B3285. 

  View the daytime temporary diversion route.

  Work to finish Carland Cross Junction will also continue in March with overnight closures (8pm to 6am) of the roundabouts and slip roads. Overnight traffic can join/leave the A30 at Chiverton via Truro, or at Summercourt via the Ladock Valley. 

  Lane closures on the A30

  Moving 24/7 lane closures are continuing on the A30 westbound in order to complete verge works, landscaping and other finishing work. These lane closures will finish in mid-March.

  B3284 north reopening 

  Due to the weather conditions last week, the reopening of B3284 north of Chybucca has been delayed and is now expected to open early this week.

  Lane closures on the A30

  Moving 24/7 lane closures are continuing on the A30 eastbound in order to complete verge works, landscaping and other finishing work.
  These lane closures will take place at different locations along the new A30, eastbound and westbound until March.

  Progress on reopening local roads around the A30

  Since the new A30 dual carriageway opened in June we have been working on completing and reopening the old A30 (as the B3288 / B3285) and other local roads.

  Unfortunately, along with the regular challenges of the weather there have been major issues with resource in our supply chain, and our programme has been delayed. 

  We are now expecting the old A30 to reopen as the B3288 between Chybucca and Boxheater (near Zelah) in mid-February 2025. We expect the rest of the local work to be complete by Spring 2025. 

  We apologise for these delays and thank you for your continued patience.

  Traffic lights on local roads

  From Monday 25 November there will be daytime temporary traffic lights on the Chybucca roundabout leading to the the B3284 south of the A30 for 3 weeks. They will be in place during off peak hours from 9:30am to 3:30pm everyday, except Sundays, until 13 December.

  From Monday 2 December there will be overnight temporary traffic lights (8pm until 6am) on the link between the two Carland Cross roundabouts for 5 nights. 

• 22 October 2024

  UPDATE - Overnight closures around Carland Cross

  We've made some changes to our overnight closures around Carland Cross this week.

  Instead of full closures, there will be traffic lights in place so that residents can access the A39 via the B3285 (and vice versa) using the Carland Cross roundabouts. This allows for the Cornwall Highways work further south on the A39.

  During these overnight closures: 

  • the eastbound slip road from the A39 to the A30 will be open
  • the westbound slip road from the A30 to the A39 will be closed

  The A30 dual carriageway will be open as normal during these closures. 

  Signed diversions will redirect traffic to other routes as appropriate.

  Please allow extra time for your journeys and take extra care when driving at night.

  UPDATE - Closure of the B3284 north from 28 October 

  From Monday 28 October at 9am, we will be closing part of the B3284 north link to Chybucca junction. This will be a 24/7 closure for four weeks. To clarify - the closure will not affect the eastbound slip road off the A30 at Chybucca or the route to Shortlanesend south of the A30. 

  Please plan ahead and allow extra time for your journeys during these works.

  Other roadworks to note in the coming months

  24/7 lane closures are now in place on the A30 eastbound in order to complete verge works, landscaping and other finishing work.

  These lane closures will take place at different locations along the new A30, eastbound and westbound over the next few months. 

  There are also:

  • overnight full closures of the A30 eastbound week commencing 4 November.
  • Chiverton gyratory overnight closures in December

  Roadworks at Chiverton junction

  As part of our finishing work on the A30 and local roads, we'll be implementing some more traffic controls. This means we can continue our work to complete the project throughout the autumn. 

  From Monday 14 October at 9am, we will be implementing lane restrictions on and around the Chiverton gyratory for 6 to 8 weeks. These will operate from 9.30am to 3:30pm each day in two main phases. 

  These restrictions will be in place so that we can finalise work on the retaining walls around the junction, and allow the workforce to do this safely.

  • the first phase will narrow the A390 approach to Chiverton to one lane
  • the second phase will narrow the A3075 and B3277 approaches to one lane. There will also be reduced lanes available on the roundabout itself in order to manage traffic joining and leaving the A30, or accessing local roads. 

  Through traffic on the new A30 dual carriageway will not be affected by these restrictions. 

  Please plan ahead and allow extra time for your journeys during these works.

  Overnight A30 closures

  There will be overnight closures on the A30, eastbound only, starting on Monday 14 October for up to four nights. Closures will run from 8pm until 6am. 

  The signed diversion route will:

  • take traffic off at Chiverton Junction and follow the A3075 to Goonhavern
  • then take the B3285 to re-join the A30 at Carland Cross Junction. 

  Please allow extra time for your journeys and take extra care when driving at night. 

  Future closures and restrictions 

  Looking further ahead, there are several key closures planned as follows:

  • Night-time closures of Carland Cross Junction and a joint closure of part of the A39 with Cornwall Council during the week commencing 21 October.
  • A full closure of the B3284 north starting the week commencing 28 October.

  Full details will be shared on this page in due course.

  B3277 diversion map.

  A3075 temporary traffic lights - Monday 9 September for up to six weeks

  We’ll install temporary traffic lights on the A3075 near Chiverton junction

  They will operate from 9.30am to 4pm each day.

  The lights won't be in place during the Little Orchard cider and music festival.

  Upcoming A30 overnight lane closures

  We'll need further overnight lane closures on the new section of the A30 later this autumn.

  These will be on the east and westbound carriageways in different locations. The closures won't limit the use of the new A30.

  We’ll give you more further information on this page.

  Please plan ahead and allow extra time for your journeys.

  Memorial motorcycle run

  The 37th annual Martin Jennings Memorial motorcycle run through Cornwall will take place on Sunday 15 September.

  This is a large scale motorcycle event raising money for charity. Up to 2,000 riders are expected on a number of county roads.

  The route includes a section of the new dual carriageway. Riders will join the A30 at Cornwall Services. Between 1pm and 3pm they’ll ride westbound before leaving the A30 at Camborne.

  There are no traffic restrictions in place but this section of the A30 will be very busy. There are likely to be delays

  Please plan ahead. Avoid this section of the A30 in the early afternoon, if you can. If possible, find an alternative route.

  New A30 dual carriageway enters final stages

  We’re now in the final stages of our A30 Chiverton to Carland Cross upgrade project and will soon be preparing for the opening of the new dual carriageway later this year, before the school summer holidays.

  Since the scheme received its Development Consent Order in February 2020, we’ve faced some significant challenges but despite these, we’ve made good progress.

  The original Delivery Plan target date to open the new dual carriageway to traffic was the end of March 2024. However, since the start of construction, the programme of work has had to adapt to the effects of both the pandemic and growing weather challenges.

  Between January 2021 and August 2023 there were 14 Met Office classified storms and since last August alone there have been an unprecedented total of 10 storms affecting Cornwall. As a result of the impact of the recent bad weather, we’re now expecting the road to be open for traffic in June.

  The recent Chiverton flyover and Chybucca junction openings were significant milestones for the project and we’ll now be progressing with work on the new Carland Cross junction and ‘green bridge’ structure at Marazanvose.

• 19 December 2023

  Chiverton flyover partially reopened

  We are now in the final stage of the project – huge progress has been made in 2023 and we are now preparing for the opening of the new A30 in 2024.

  Last week we partially opened the Chiverton flyover - a major milestone for the project. This has alleviated congestion as we now have one lane of east-west traffic in either direction bypassing the interchange without queuing. Local journeys north and south are also improved as drivers will no longer have to interact with the A30 mainline traffic.

• 31 May 2023

  Chiverton Cross interchange to be installed

  We've reached a major milestone on the project and will be installing the new Chiverton Cross interchange in June.

  Following the installation traffic will use a new layout at Chiverton.  The new layout will keep access open to the A390, A3075 and B3277 while we continue our work this year.

  Watch Tolgroggan bridge lift

  We installed a new bridge over the A30 in double-quick time last weekend as part of our Chiverton to Carland Cross road dualling scheme in Cornwall.

  The Tolgroggan access bridge has spanned the A30 near Zelah for 32 years and needed to be replaced to accommodate the new dual carriageway and the existing road between the Chiverton and Carland roundabouts.

  Despite mist and mizzle, weather conditions and wind speeds remained suitable for the lifting operation and the new 137ft (42-metre) twin-beam overbridge was lifted into place by a 650-tonne crawler crane on Saturday afternoon.

  Our Engineers then undertook tying-in work on the bridge, dismantling and transporting of the crane and extensive site and traffic management clearance. We managed to reopen the A30 to motorists at 2pm on Sunday – some 16 hours ahead of the anticipated opening on Monday morning.

  The new bridge weighs 275 tonnes, the equivalent weight of 23 double decker buses or 887,097 standard Cornish pasties and will eventually span the existing A30 road and four lanes of the new carriageway.

  You can see a timelapse footage of the weekend works in the video below.

  Now in position, our work will concentrate on construction of the new road, with the existing bridge to be demolished later this year.

  Neil Winter, National Highways Senior Project Manager for the A30 Chiverton to Carland Cross upgrade, said: “We thank people for their patience and co-operation while we carried out the work. The operation went as planned and although the weather wasn’t the greatest, conditions were favourable and the preparation work paid dividends.

  “It’s a key milestone for the project, and now that we have the new bridge in place we will be able to switch our attention to the other structures along the route.

  “As part of the scheme, we’re building 13 new structures in all, both under and over the new A30, with one existing underbridge at Two Burrows, a short distance from Tolgroggan, being refurbished.”

  

• 11 January 2023

  Work continues on all structures

  We’ve continued to work on all the structures, this included pouring concrete bridge decks at Chiverton, Chybucca, Tolgroggan and Carland. We’ve also installed bridge beams at Marazanvose allowing us to plan for the concrete deck pour and other work on this structure.

  We’ve made good progress on our drainage work with the use of a specialist trenching machine in areas where there is hard rock.

  We also completed our roadworks between Chybucca and Chiverton. This meant that we were able to realign the A30 through the Four Burrows and Chiverton junction area at the beginning of December.

  Next steps

  We’re getting ready to install a new bridge at Tolgroggan. This will replace the existing bridge which we will demolish later this year. We will need a weekend closure of the A30 to carry out this work safely, we’re just finalising our plans and will provide an update on the date for this shortly.

  

  (Bridge beams being lifted into place last year for the new bridge at Tolgroggan)

  Over the next few months we’re aiming to complete the:

  • underbridges at Chiverton East and Carland Cross
  • road surfacing in the Hill View area on the A30 westbound carriageway
  • roadworks at Henver Lane.This will allow access to the northern part of the new Trevalso Lane underbridge to start over the next few months.

  We will also be:

  • changing the traffic management at Trevissome Park to allow access to the A390
  • realigning the A30 at Zelah so that we can start work on the underbridge there.

  Cornish home produce is core to greener A30 road upgrade

  

  Cornwall’s very own china clay mining industry is playing a big part in the construction of our major A30 Chiverton to Carland Cross upgrade.

  Sustainability and reducing the carbon footprint are key drivers behind construction of the 8.7-mile dualling scheme, and to that end contractors Costain Jacobs and supply chain Aggregate Industries are tapping into natural Cornish materials and a significant investment in local companies.

  Larger infrastructure projects typically use millions of tonnes of aggregate – representing a large carbon footprint – but as with other modern-day road building schemes, the A30 project is utilising a by-product from the china clay mining industry.

  The residue, known as stent, would normally have no use and be left in white spoil heaps, scarring the local landscape. Instead, the material from the Littlejohns Pit near St Austell is being processed into sustainable secondary sand and aggregate for construction use.

  And just down the road, this is now being used as an engineering alternative across the A30 project, not only reducing the embodied carbon but also saving on the transport carbon cost.

  Compared to the 5kg Carbon Dioxide equivalent (CO2e) per tonne carbon emission of virgin aggregate, the locally imported material is around 2kg CO2e per tonne, representing a reduction of around 3kg CO2e per tonne of aggregate used.

  Added to that, Aggregate Industries has also invested over £4 million in the nearby Melbur Quarry at St Stephen to produce more carbon friendly warm mix asphalt for the new road surfacing.

  Fully approved by National Highways, warm mix asphalt is a greener process that has less impact on the environment, with reduced hydrocarbon emissions and greenhouse gases. Due to its lower temperature, it is also safer for construction workers to use.

  Warm mix asphalt is produced using temperatures up to 49 degrees Celsius lower than that used for traditional hot mix asphalt so less energy is needed in the heating process, meaning less fuel and a reduction in the plant's carbon footprint.

  Roads Minister Baroness Vere said:

  “The A30 Chiverton to Carland Cross upgrade will reduce congestion, improve journey times and provide much-needed connection for local businesses.

  "By using natural Cornish materials, we are also ensuring the scheme has a much lower carbon impact and provides a further boost to the local community, which is exactly the kind of innovation we want to see as we strive towards a net zero road network.”

  Nick Simmonds-Screech, National Highways Project Director for the A30 scheme, added:

  “We’re already really proud of our environmental and ecological work – we’re forecasting a net biodiversity gain in the region of 20% – and this greener way of working also spreads to our construction methods and material supply.

  "We all have a part to play in reducing our carbon footprint and adapting to climate change, and modern road building methods are certainly playing a part in this.

  “The move towards warm mix asphalts allows us to not only achieve huge efficiency savings but also reduce carbon as we strive for net zero by 2040.

  “Carbon reduction, along with ensuring our roads provide smooth, safe, and efficient journeys for motorists, are key and something we are constantly striving to improve for generations to come.”

  As part of our Net Zero Plan, we're committed to reducing our maintenance and construction carbon emissions to net zero by 2040.

  On the Cornwall upgrade, Costain Jacobs and its contractors are also tapping into local skills and supplies as construction on the £330 million scheme progresses.

  Aside from the aggregate and asphalt production, this includes the:

  • employment of site managers and engineers from the local area
  • use of Devoran Metals for reinforcement on the project
  • daily use of a local scaffold supplier
  • use of smaller suppliers of timber products
  • engagement with local colleges and the Camborne School of Mines.

  John Lee, Costain Project Director, said:

  “It’s been good to tap into local skills and materials, we’re making excellent progress with the construction works and on course for the new road to be open to traffic in winter 2023.

  “We’re also committed to working with National Highways and its Net Zero Plan and the use of warm mix asphalts and china clay by-products is playing a big part in the A30 helping to reduce the carbon impact of construction.”

  Exciting archaeology finds on the A30

  Since August 2020, the A30 team have been conducting archaeology investigations to record, report and preserve the archaeological findings along the A30 Chiverton to Carland Cross scheme.

  The Archaeological Contractor, Cornwall Archaeological Unit (CAU), has discovered artefacts from the Mesolithic/Neolithic transition period (around 6,000 years ago), the Bronze age (around 4,500-3,000 years ago), the Medieval period (around 12-13^th Century), and the World War Two period.

  Throughout the summer of 2021, we have hosted volunteer events to assist with our archaeological investigations in targeted areas.

  Targeted areas include Penny-Come-Quick and Ventonteague, where the finds include a clearly defined post ringfeature (pictured). We are still progressing with the excavation of the surrounding area to uncover the full archaeological background; however initial investigations show that this is likely to be the remains of a stone circle.

  We are also conducting a flint scatter in an area known as Ventonteague. We have found over 6,500 flints in this area and are continuing investigations to locate the epicentre of the flint scatter activity. These flints suggest the use of Mesolithic hunting weapons, processing tools such as scrapers and axes, suggesting an that there was an extensive knapping area at Ventonteague.

  The flint from these flint scatters is likely to have been transported from areas such as the neighbouring coastline in Devon or Somerset as flint does not naturally occur in this area of Cornwall. The knapping area at Ventonegue can therefore be indicative of a manufacturing area where a range of tools would have been produced for a variety of uses, such as for hunting game and butchering meat. Investigations have uncovered signs of a 6,000–8,000-year-old water culvert in this area, supporting the theory of repeated settlement and activity in the area.

  Other excavations have uncovered two roundhouses in the Tolgroggan area which are likely from the Late Neolithic/Early Bronze Age and would have been used as a domestic dwelling. One roundhouse also featured a post ring (a central area of pits and post/stakeholes), flint tools and a pot located centrally in the ring centre.

  Development Consent Order granted

  We were granted a Development Consent Order (DCO) on 6 February 2020 which allows us to build the design as submitted to the planning inspectorate (PINS).

  We awarded a contract for the work to Costain on the 31 March 2020. In March, we also began preliminary works for the scheme. This includes the diversion of utilities, survey work to inform the detailed design and some site set-up work as we move through the summer.
