The bascule bridge was originally due to come into service in 2014 but was delayed after construction problems emerged. It has been open in a limited capacity since August, with only light vehicles, cycles and pedestrians allowed across.
A report carried out by Modjeski & Masters has now confirmed that there is no need to demolish the bridge as the structure itself is in generally good condition.
The Modjeski & Masters study has found that the bridge needs new mechanical and electrical systems to bring it into full service. The repair work is expected to cost about US$6.7 million and take 24 months. The project will also include some repairs and strengthening of the superstructure and substructure.
Work is now under way on the engineering design of the adopted solution, which will allow quotations to be solicited from contractors.
