Six expansion joints, which are vital to the operation of the bridge, had reached the end of their lifecycle.
Lane availability was an issue and there was a need for a more financially efficient and more sustainable method as well as reduce safety hazards associated with all previous ramping systems.
During the development, it was realised that substantial environmental benefits would accrue and that substantial lane availability costs would be avoided through maintaining normal traffic speed.
A new temporary over-ramp was developed to allow the workforce to repair the joints underneath, while traffic passed overhead.
