Innovating in a compact environment

The East Kent Access Phase 2 project involves building a jacked deck tunnel under the A299 at Cliffsend. This innovative underpass enhances regional connectivity while minimizing disruptions. Utilizing established jacked structures and alternative abutments, the project emphasizes efficient engineering methods and sustainability. With an average progress rate of 2m per day, the collaboration between VolkerFitzpatrick and HOCHTIEF JV ensures optimal execution. The design and construct submission reflects thorough value engineering, setting a precedence for future infrastructure developments in compact environments.
