The move will see the Amberon, Barrier Services, Forest Traffic, JTM Signs and MLP Traffic operations come together as one.
Core Highways has 1,300 staff and more than 1,000 directly employed operatives working in a combined turnover business of £120m.
The consolidation will see Core Highways become one of the largest temporary traffic management and barrier companies in the UK, with almost 40 depots across England and Wales and further growth planned.
Lizi Stewart, CEO of Core Highways, said: “Becoming Core Highways means that we can combine our knowledge and expertise for our customers across England and Wales, giving them access to more skills and expertise in temporary traffic management, barrier solutions and events signage.
“Our dedicated and knowledgeable team have hundreds of years of experience in providing solutions for customers across England and Wales’ road networks at high and low speed.
“As a team we are stronger together, supporting one another and our customers to deliver. Becoming one will give our customers quicker access us to our deep well of technical excellence as well as our innovation and best practice, such as our Decarbonisation Project Roadmap and our award-winning Digital Care Initiative.
“Our business is our people, and by better connecting our passionate, skilled and customer focussed team under the Core Highways brand, we are better able to support our customers and their stakeholders.”
