Project Summary

The £20 million Beaulieu Parkway Bridge project demonstrated a highly complex feat of civil engineering, with the GRAHAM team constructing a curved bridge superstructure using innovative methodologies. The bridge, weighing in at over 2400 tonnes and 161 metres long, is one of the longest bridge structures ever installed in the UK using SPMTs and was successfully installed over two weekends in September and October 2022.

The detail

As Principal Contractor and Principal Designer, GRAHAM led the project constructing the 161m long three span road bridge connecting Chelmsford’s new relief road at the Beaulieu development with the realigned Boreham interchange to provide a convenient new link between the A12 and A130. The use of Self-Propelled Modular Transporters (SPMTs) for installation represented a ground-breaking approach to transportation and installation of the bridge, reducing disruption and railway possessions, and ensuring greater programme certainty.
