Construction work has begun on a key bridge of the High Speed 2 (HS2) project, New Civil Engineer reports. The bridge is located at Calvert, Buckinghamshire, where the East West Rail line will cross the HS2 route. The HS2 contractors are collaborating with those working on the East West Rail project to minimise disruption and simplify the process.
Foundation work for the bridge is due to begin in mid-April. A rotary bored piling rig will be used to install the 38m deep foundation piles for the bridge. The HS2 line which crosses under the bridge will be sunk in a 4km long cutting to minimise disruption to views and the local community.
The next step after the foundation piling is complete will be the construction of 8m high abutments on either side, which will support the main bridge deck. The deck is scheduled to be installed next year. Once in place, the HS2 contractors will hand the project over to East West Rail for the installation of track and signalling.
Network Rail North West and Central region managing director Tim Shoveller commented:
“Our approach at Calvert is partnership work at its best as we build a new railway to transform journeys and connectivity across the heart of the country.”
He added: “By Network Rail joining forces with HS2 Ltd and our contractor East West Rail Alliance, the major construction work can be done efficiently and disruption for the local community can be minimised as both new railways are built.”
Calvert Green Parish Council chairman Phil Gaskin had previously complained about the lack of joined up thinking between the two sets of contractors. Speaking at a government cross-party Transport Committee meeting, he said that the conflict of interest was disrupting traffic around Buckinghamshire.
