MOLISSON STREET BRIDGE – Kyneton, AUSTRALIA
MOLISSON STREET BRIDGE – Kyneton, AUSTRALIA
The Molisson Street Bridge is located in Kyneton, Northern Victoria, Australia and has served the past 100 years for traffic over the Campaspe River.
It is the first steel bridge structure protected with ZINGA for VicRoads Design.
In the last decade it was showing rapid deterioration caused by corrosion.
Therefore it was decided to treat this bridge in May 2007.
The old coating had to be removed completely because of this rapid advancement of corrosion.
Site inspection in May 2007 (before ZINGA application)
Note the increased beam corrosion.
Typical view of ZINGA coated steelwork.
All rivets, edges and bolts were stripe coated.
As previous coating system was lead based, the complete bridge had to be encapsulated.
All steel bridges flex. When using this ZINGA system, the coating will never become brittle and will remain flexible throughout the service life of the coating system, thus preventing possible coating failures.
