The B01366 Bridge (Cold Tea Creek Bridge) is located on the Pacific Highway, New South Wales and passes traffic over the Cold Tea Creek. The structure was investigated and found to be suffering from chloride induced reinforcement corrosion. Various elements were showing visible signs of concrete deterioration in the form of cracking, delamination and spalling. A Hybrid CP system was designed to arrest any active corrosion within these elements and to provide ongoing corrosion protection to the reinforcement for 30 years. The system was installed by RMS with construction phase technical support provided by Infracorr. Infracorr commissioned the Hybrid CP system in July, 2017, with the assistance of RMS.
