The expected works will be carried out by the Midland Metro Alliance on behalf of the West Midlands Combined Authority.
The Midland Metro Alliance consists of the West Midlands Combined Authority, which owns the West Midlands Metro, as well as a consortium of designers from Egis, Tony Gee, Pell Frischmann, and Colas Rail, alongside Colas’ sub-alliance partners Colas Ltd, Barhale, Bouygues UK and Auctus Management Group.
The work will require the closure to vehicles of Paradise Circus and Centenary Square.
Metro work totalling £1.3bn is planned for Birmingham. The existing 25km line runs from Grand Central New Street Station in Birmingham city centre to Wolverhampton St. George in the north. Six new lines, totalling 32km, are planned and will extend and branch off the existing line.
The Birmingham Westside Metro extension will run between Grand Central and Hagley Road in Edgbaston, with five new tram stops. The first phase of work – in which the phase starting in September is included – is expected to open to passengers at the end of next year. It will run from Grand Central to Centenary Square. The second phase of the route, expected to open for passenger service in 2021 in time for the 2022 Commonwealth Games, will continue to Edgbaston.
West Midlands mayor Andy Street said: "Inevitably with such a massive engineering project there are going to be knock-on effects to existing traffic as work takes place, but I would urge people who may be affected to consider the bigger picture. By better connecting our towns and cities we create a transport network that strengthens economic growth, creates jobs, and helps bring greater prosperity to this region.”
City of Wolverhampton Council leader and WMCA portfolio lead for transport, Roger Lawrence, added: "Extensions to the West Midlands Metro are key to ensuring this region has the right transport links in place for the arrival of High Speed 2.”
