Tunnelling Through the Chilterns

Using the largest STP in Europe and the first Variable Density TBM in the UK, the Align JV completed the twin bore 16km drives through the Chiltern Hills in 2024. The drives featured multiple challenges that have been overcome with innovative tunnelling solutions. This presentation will detail the development of these solutions from the design phase, and their implementation throughout construction, as well as the benefits and challenges faced along the way.
