Jackson was highly commended in the ICE South East Awards for its work on the Gade Valley Expansion Joint Replacement Scheme on the M25.
The project involved the replacement of two expansion joints on the Gade Valley Viaduct, at Junction 20, which were skewed by more than 30 degrees.
Using temporary over-ramps which were originally developed for a previous Jackson project on the QEII Bridge, this innovative temporary works solution was successfully re-deployed following minimal modification, allowing the team to complete the project with very little disruption to traffic.
This ramp solution has the potential to be re-used at a further 26 locations across the M25 network, and they are currently being used on a similar project at New Haw Viaduct.
Whilst in-situ, 30.2 million vehicles drove over the ramps at Gade Valley, their drivers were largely unaware of their presence. Considering this number in the context of delays that could have been caused by the works, the benefits for this temporary works method are unquantifiable, and in that respect, this innovation has been a triumph for the industry.
