The Australian and NSW governments are jointly funding the $55 million project, which is part of the NSW Bridges for the Bush program.
The project is replacing the old crumbling Kapooka road over rail bridge on the Olympic Highway with a new two-lane bridge over the main southern railway line.
Kapooka Bridge was built in the 1880s and carries more than 150,000 truck movements each year. The new structure will remove the only remaining weight-constrained bridge on the Olympic Highway, opening up an extra 315 kilometres for more productive freight trucks.
Drainage work at the site is also 50% finished and work will soon start on building soil walls to help reinforce the new bridge’s ends.
Chair of NSW Freight Advisory Council Ron Finemore said the bridge would provide a safer route for trucks
“B-doubles [trucks] for example carrying general freight or livestock from southern NSW to Victoria will now experience a safer journey and greater productivity along this vital transport route,” Mr Finemore said.
“The last time I stood next to the old bridge with the minister and local member, longer trucks had to cross over to the wrong side of the highway to negotiate the tight dog-leg bends which was extremely dangerous.
The bridge is expected to be finished by September 2016, weather permitting.
