Four bidders have been selected by the Highways Agency for a £184m motorway upgrade scheme.
The contractors are Balfour Beatty, Carillion, Costain and a Bam Nuttall/Morgan Sindall joint venture.
The £184m contract was awarded under the Highways Agency’s National Major Projects framework.
The scheme will upgrade a 17-mile stretch of the M60 and M62, part of the Manchester orbital route.
The ‘smart’ motorway will aim to improve capacity and journey times as well as reduce congestion by controlling traffic flows through remote technology in response to real-time monitoring of traffic volumes on the network.
The project will be managed through a collaboration agreement, which will enable the firms to share knowledge and best practice.
Costain chief executive Andrew Wyllie said: “The upgrading of our road network infrastructure is essential to maintaining and improving connectivity among the various regions of the UK.
“We look forward to working in collaboration with the Highways Agency and with our partners to deliver this project, using the latest in new and innovative traffic management technology.”
Work will start in July and is expected to be completed in autumn 2017.
