HS2 has been granted approval for major Birmingham viaducts

HS2 Ltd has been granted planning permission by Birmingham City Council for two viaducts which will take the new high speed railway into Curzon Street Station in the city centre.

 

Curzon Viaduct No.3 and Lawley Middleway Viaduct are part of the Curzon Street Station Approach area, which is made up of four connected viaducts between Duddeston Junction Viaduct and Curzon Street Station in central Birmingham.

 

The other viaducts are Curzon Street No.1 Viaduct (furthest from the station) and Curzon Street No.2 Viaduct which is currently undergoing a planning application.

 

A number of design refinements have resulted in a shorter construction programme and less concrete needed to build the viaduct, bringing positive environmental and community benefits.

 

The viaducts are being designed by a Design Joint Venture of Mott MacDonald and Systra and architects Weston Williamson + Partners, all working for HS2’s civils contractor Balfour Beatty VINCI joint venture.

 

The Curzon Viaduct No.3 is approximately 300 metres long, the height above ground level varies between 5 metres to 6 metres, it is 65 metres wide at the widest point and will be supported by 30 piers. As it approaches Curzon Street Station, the deck of the viaduct widens from a single deck at the eastern end to four separate decks at the western end.

 

The viaduct will widen to four separate decks near Curzon Street Station to maximise daylight in the public space underneath. V piers have been developed to support the viaducts because they take up less room at ground level and will also have a side recess for future potential services to be visually integrated. As well as separating the viaduct into four separate decks, the V piers will also help to maximise the opportunities to create a usable and flexible public space under the viaduct.

 

As Curzon Street No.3 Viaduct crosses the Digbeth Canal, the concrete V piers are substituted with four inverted steel piers which reference the heritage of canal-side cranes in Birmingham. This also means the Digbeth Canal area will remain a visually attractive area to the public, combining the twenty first century HS2 infrastructure and the nineteenth century Digbeth Canal area, ensuring a positive legacy for this part of the city.

 

Through the development of the designs, the width of the viaduct has been reduced from 71 metres to 65 metres. The Curzon Street Pumping Station that was previously located south of the viaduct has been removed from the design as water that gathers on the viaduct will now be drained into either an attenuation pond – an area on the ground that temporarily stores excess water before releasing it in a controlled way, or attenuation tank located underground.
