Installation
For the installation of the bridge, the work had to be done during a total line blockage and therefore night time possession shifts were used. The crane was then set up on the level crossing making sure all-out riggers missed the rails and a temporary works lift plan was designed and supervised for the crane installation. Once in position the bridge components were backed up to the crane on trailers. Operatives then slung the loads and the bridge was placed into its final position. Once in its exact location, the trestles were bolted down using concrete anchor bolts. All components were rechecked and tightened accordingly. This was then repeated the following week to fix the stair cases. Due to the planned works, the management team had to monitor the predicted weather for installation as high winds would propose difficulties – thankfully the time of year works were carried out meant the weather caused no issue.
Operatives then worked on a regular night shift basis to install temporary festoon lighting cable on the bridges decking. They continued to carry out regular checks on the lighting condition during each shift.
