Freyssinet ElevArch® Bridge Lift Trial

On 26 October 2016, Freyssinet’s ElevArch® technique was trialled in a live demo in front of 120 guests from the rail sector, including Network Rail, Aktins, Arup, Arcadis, DfT and J. Murphy Group.

The 161-year-old, 220 tonne masonry arch bridge on Moco Farm in Buckinghamshire was successfully raised 900mm using ten 50 tonne jacks.

Freyssinet was invited to participate in RSSB’s Innovation Programme for The Avoidance of Bridge Reconstruction in 2014. From this, the company’s innovative ElevArch® concept was born - a revolutionary technique for vertically jacking masonry bridge arches, designed to minimise intrusion to the rail environment compared to other techniques, significantly reducing cost, time and resources. The ElevArch® lift trial was the result of two years of innovative thinking and careful planning.

Saltings Viaduct Expansion Joint Replacement

The A465 Saltings Viaduct on the Neath Interchange is a busy dual carriage way, bringing traffic to and from the Swansea area.

Assessment of the viaduct indicated that essential maintenance was required to replace the expansion joint located on the east side of the bridge on both the westbound and eastbound carriageways.

Freyssinet was appointed by the client, Cemex, on behalf of South Wales Trunk Road Agent (SWTRA) for the Welsh Government to design, supply and install a new expansion joint on the bridge.

Thousands of vehicles use the bridge every day and as such, every effort was made to minimise inconvenience to road users. Freyssinet installed a cover plate system, which allowed traffic flow during day time hours and the work was completed during night time closures.

After removing the existing joint, Freyssinet’s in-house hydrodemolition team Aquaforce removed the surrounding concrete, before installing a fully galvanised Freyssimod LW 480 modular type joint, featuring new swivel bearing supports which allows good operation for whole life.

Freyssinet Immingham Structure Slide

During Christmas 2015, Freyssinet successfully slid a concrete bridge beneath the line of the Immingham to Ulceby railway line, just off Rosper Road in South Killingholme. The completion of these vital works is a critical part of the Highways England A160/A180 Port of Immingham Improvement Scheme in North East Lincolnshire, which will enhance road access into the port on this strategic route.
