One of our teams recently installed a 84 metre long pontoon in Berkshire to support the £848 million M4 smart motorway extension project.  The expansion of the busy section of road from 2 to 3 lanes over the River Thames near Bray requires a bridge extension.  The tow path has been safely diverted onto the water by utilising a bespoke Pontoonworks modular pontoon installation.  The platform is fully fenced with Combisafe edge protection, access and egress to and from the marine ply and baize covered walkway  using 6 metre ramps ensures pedestrians are kept safe from the works and the hazards of the waterway.    This installation will continue to be used during the initial construction of a coffer dam to widen the bridge abutment through to completion of the structure.
