Construction of a relief road linking two major housing schemes near Broadbridge Heath, in West Sussex, included building abridge over the A24. The structure, part of a new junction withthe busy dual carriageway, had to be built quickly, with minimum impact on both the main development works and traffic flow on the trunk road.

Tensar’s TensarTech® TW3 retaining wall system was used to build the load bearing bridge abutments and wing walls for the new bridge. The geogrid-reinforced soil structures with mechanically connected concrete block facing, support the 28m span bridge deck. The modular system was fast and easy to install, reducing the number of crane lifts and keeping A24 lane closures to a minimum.
