In 2008, while the Planning Transport and Estates Department considered how to protect the bridge long term, Cornwall County Council consulted with Metallisation and TSSEA. The aim of the discussion was to explore and evaluate thermal spraying as an option to protect the bridge from corrosion, instead of a standard paint system.
Scott Perry, civil engineer, Cornwall County Council, says: "Following consultation with Metallisation and TSSEA and considerable research into corrosion protection, we opted for the Highways Agency specification for thermal spraying due to its proven durability and long term corrosion protection.
