Transport for West Midlands (TfWM) has submitted plans for the £200m, seven-mile expansion of the Midland Metro.
The metro line, which presently stretches from Wolverhampton to Birmingham, will now be expanded from Wednesbury to the new DY5 Enterprise Zone at Brierley Hill.
As per the proposed route, the line would run through Great Bridge, Horseley Heath, Dudley Port, Dudley town centre, the Waterfront and Merry Hill, and end at Brierley Hill town centre.
The scope of the work includes extensions to Wolverhampton interchange and the HS2 terminal at Birmingham’s Curzon Street.
Mayor of the West Midlands Andy Street said: “It is hard to understate just how important this project is to the Black Country. The business case shows that for every pound invested in this project, it will return £2.50 for the local economy.
“It will align employment, education, health and tourism along the corridor, stimulating investment in the Black Country and enabling the building of 50,000 homes and bringing 170 hectares of brownfield land. It will also be important for passengers. It will more than halve journey times from some of the stops along the route into central Birmingham.”
