A suspicious fire on the bridge at Domain Rd last month has caused more than $2 million damage and contractors are preparing the site for demolition.
The initial investigation showed the fire destroyed around a five metre section of the expanded polystyrene blocks and concrete deck of embankment two, damaged
some of the concrete facing panels, the concrete deck beams and the columns of one of the Domain Road bridge B abutments.
For the past three weeks design engineers and the insurance assessors have carried out inspections of the damaged section of the Domain Road interchange and undertaken a range of tests to gain a better understanding of the extent of the damage.
The engineers looked for damage to the reinforcing steel, particularly where it has deteriorated in the heat and has caused cracking to the concrete.
Preliminary estimates put the cost of repair in excess of $2 million, however the exact figure will not be known until additional strength tests have been completed and the contractor starts dismantling damaged components later this week.
