The completion of the road bridge over the level crossing near to Lewes in East Sussex was a 2 year project carried out by a major contractor Alfred McAlpine. The requirements was for the installation of weldmesh to under carriages to prevent birds from gaining access to the abundment areas.
Due to the movement in the bridge it was only possible to install fixings into the top section of the bridge of which it was decided to use stainless steel m6 expanding bolt screws with rubber seals to prevent a chemical reactions with the galvanised protected metal. Due to the uneveness of the bridge lines and that we were unable to install the weldmesh to the metal girders it was decided to install and cut the weldmesh onsite.
The works were completed over 2 stages as we had to allow for the front brickwork to be installed before the installation of the wire as it restricted access to other personnel. Weldmesh is a perminant option and the works had to last in excess of 25 years.
