Cathodic protection of a historical rail bridge

摘要

The rail bridge over the Silvermine River near Clovelly, Cape Town, is a historically significant bridge structure. The seaside bridge was constructed in 1890 and an additional rail line and adjacent roadside bridge was added on the upstream side in 1926. The bridge is situated in the estuarine mouth of the Silvermine River and has been subjected to extreme marine environmental exposure conditions.
