Innovative soil stabilisation technique benefits highways project18th Feb 2019

A leading civil engineering firm has used an innovative soil stabilisation method to minimise disruption on a highways scheme.

Jones Bros Civil Engineering UK was appointed to design and build the final phase of the Llangefni Link Road by Isle of Anglesey County Council.

The site, based on greenfield, contained 7,000m3 of surplus soil from an industrial site build, which the contractor treated on location to avoid haulage vehicle journeys from Llangefni to landfill.

It was then used within the construction process, helping both the scheme’s sustainability and local motorists, says project manager Robat Williams.

He said: “By stabilising on site, we drastically reduced disruption to local roads, as traffic management was only required for two of the contract’s 12 month duration.

“Being met with a significant amount of then-unusable material was a unique challenge, but our solution and approach made the project self-sufficient with all work carried out by our in-house team.

“The link road further cements our reputation as a leading highways specialist, with our team also commencing work at the nearby Caernarfon and Bontnewydd bypass as well as on the A49 in Wigan.”

The Llangefni Link Road will be vital in facilitating the delivery of Grwp Llandrillo Menai’s Masterplan to develop their Llangefni Campus into an internationally-renowned Energy and Engineering Training Facility and supporting the expansion of Bryn Cefni Business Park. It also aims to reduce congestion in the town, as well as promote the Welsh Government’s active travel policy through the use of shared paths for pedestrians and cyclists.

Ruthin-based Jones Bros constructed 800m of new highway to complete the route, in addition to reconstructing an old roundabout and building a new one from scratch.

The project required 10,000m2 of asphalt, 800 metres of drainage, 2km of kerbing, and the creation of an attenuation pond to control surface water discharge.

The Link Road has received funding from the Welsh Government, the Isle of Anglesey County Council, Grŵp Llandrillo Menai, and the Nuclear Decommissioning Authority.

Ken Skates AM, Minister for Economy and Transport and Minister for North Wales, opened the link road during an official visit to Anglesey.

He said: “A high quality and connected transport system is absolutely vital to achieving economic growth in North Wales and I am delighted to officially open the final section of Llangefni Link Road, which is key in enabling people to access jobs and services.

“The Welsh Government is investing hundreds of millions of pounds in transport infrastructure in North Wales and the Llangefni Link Road is a vital part of our vision of delivering better transport connectivity.

“The completion of this scheme is a clear demonstration of our commitment to Anglesey and the wider area.”

Anglesey’s portfolio holder for highways, waste and property, Councillor Bob Parry, added: “The Llangefni Link Road will help secure significant economic benefit opportunities for Llangefni and Anglesey.

“It will provide a key driver for the expansion of the Grŵp Llandrillo Menai campus and further training opportunities for our young people. The project will also improve access to our Enterprise Zone sites and A55 expressway, and help overcome traffic constraints in Llangefni.”

Established in the 1950s, Jones Bros is now being run by the second and third generations of the founding family and employs more than 350 people. 

In addition to highways, it contracts in the construction of waste management facilities, flood and marine defence, and renewable energy projects around the UK.
