Highways England has completed a £100m ‘smart’ upgrade along a stretch on the M6 motorway in the Midlands, UK.
The project involved widening of 6.8 miles of the motorway from junction 11a to junction 13 to four lanes.
The upgrade forms part of a larger project to transform a 10-mile stretch between junctions 10a and 13.
The first part of the project included a 3.4-mile section between junctions 10a and 11, featuring three traffic lanes as well as a hard shoulder.
The redevelopment has taken 54,000 tonnes of road surface and 55 miles of cabling. It also involved use of 22,000 cubic metres of concrete, and installation of 213 new signs.
Highways England project manager Dave Cooke said: “The extra lane between junctions 11a and 13 adds valuable extra capacity which will really help traffic at busy times.
“It follows the upgrade introduced last summer between junctions 10a and 11a; together this will help improve journeys for millions of people every month.
“The technology means we can vary the speed limit to smooth the flow of traffic at busy times, this also helps prevent congestion caused by stop-start braking which causes queues to build at higher speeds.”
