HS2 contractors begin work on key East West Rail bridge Contractors working on High Speed 2 (HS2) have begun construction of a key bridge where the East West Rail line will cross the high speed rail route in Calvert, Buckinghamshire. To simplify both projects and reduce disruption for the local community, 3km of earthworks and bridges for the East West Rail project are being delivered by HS2’s main contractor, EKFB – a joint venture made up of Eiffage, Kier, Ferrovial and Bam Nuttall. Foundation work on the bridge began this week, with EKFB and BauerKeller using a rotary bored piling rig to install the 38m deep foundation piles for the bridge.
