Major HS2 breakthrough as West Midlands river realignment completed

HS2 has completed a major river enhancement in Warwickshire, which at 749 metres is the most significant realignment of a natural river on the project.

The re-naturalisation of the River Cole near Coleshill in Warwickshire will improve the existing river environment by creating more meander bends and enhancing habitats in the river and along its banks to maximise biodiversity.

To build the Birmingham Spur of the Delta Junction, one of the most complex construction areas on the entire HS2 route, a section of the river needed to be permanently realigned to support the construction of two new viaducts and a series of railway embankments.

In addition to environmental improvements, the design integrates recreational spaces and pathways alongside the river, drawing inspiration from the area's historical use as a boating lake by the Edwardians.

When the area is reopened to the public, communities will be able to enjoy new public spaces such as grassed embankments, footpaths, observation areas and Japanese style stepping stones over water features, which will enrich their experience of the natural environment around the river.

What’s been said?

Simon Casey, HS2 Ltd’s Head of Environment for Main Works Civils said: “As climate change continues to pose challenges, HS2 aims to create solutions that successfully integrate climate resilient infrastructure, environmental preservation and positive community benefit.

“The holistic approach to this River Cole realignment is a shining example of this and it’s incredibly exciting to see what the team has achieved. It is part of our wider Green Corridor programme and will create a valuable learning legacy for the civil engineering profession, providing a replicable model for future projects.”
