Landscape designs by HS2 show how an area around the River Cole in Warwickshire, identified as a Heritage Hotspot, can be transformed.
… reducing the height of the western viaduct…. results in a 36% reduction in materials….and a 26% reduction in the viaduct’s carbon footprint…
Two HS2 viaducts will be constructed near Coleshill, and the landscape around them will create new public spaces with footpaths and cycleways allowing people to enjoy and better understand their local heritage.
The area has a rich history, including a medieval deer park, the Tudor Coleshill Manor and the expansive Elizabethan garden which HS2 archaeologists recently uncovered.
Natural habitats will also be created for local wildlife, and access to water will create opportunities for fishing and walks around the river.
The current viaduct designs allow for space to provide a ‘nature-led’ realignment of the river, increasing its biodiversity and to provide flood compensation areas.
Habitats and ponds will create new homes for amphibians, dragonflies, otters, great crested newts, reptiles and badgers, which will all benefit from these new ecological features.
New integrated designs for the structures include reducing the height of the western viaduct from 10m to 4m, which results in a 36% reduction in materials being used and a 26% reduction in the viaduct’s carbon footprint.
Changing the girder from concrete to steel also brings environmental benefits, including reducing the use of materials and the construction time, with 97% of the steel coming from recycled sources….
Nick McGough, BBV design joint venture lead architect, added: “This is currently a complex area, with existing motorways and railway infrastructure isolating the site.
“Our design vision will use the Delta Junction as a catalyst to integrate HS2 into the landscape by creating a harmonic relationship with the railway, the site and wider landscape through local connectivity, habitat creation and biodiversity, landscape integration and flood risk mitigation.
“In the past the river had been used for pleasure boating by the Edwardians. The arrival of HS2 means the area will once again promote travel across this landscape including the installation of new footpaths and cycle ways for local people to use.”
