Precast arches
When Humes won the tender to supply three arch structures for the Ballina Bypass, its engineers took on some major design challenges - a steep gradient of 13.5 degrees, soil movement of 50mm, asymmetrical loadings, and the tightest centerline radius on an arch ever built in Australia.

Impressive aesthetic and environmental benefits, and an efficient construction method, led the Department of Transport and Main Roads to incorporate a Humes precast arch into the Wacol to Darra section of the Ipswich Motorway Upgrade. The 15m arch spans a creek which is an important wildlife corridor.

HumeDeck® modular bridge system
The MacArthur Gardens bridge in South Sydney used a clever design approach to minimise both its impact on the natural environment, and on project and maintenance costs.
The HumeDeck® modular bridge system provided the perfect solution for replacement of a timber bridge in a sensitive World Heritage Listed environment. The versatility of the HumeDeck® system allowed it to be installed on the existing bridge substructure, minimizing environmental disturbance.

I-beams
When Queensland Rail undertook a $28m upgrade of the St Lawrence Creek Rail Bridge, they were committed to implementing a long term, durable, and cost effective solution. Humes was subsequently chosen to supply 80 x 25 metre concrete girders with encased cathodic protection.

Precast elements
One-off moulds were used to create precast decorative design plinths, panels and arch facades to ensure this new bridge faithfully represented the Art Deco style of the original.
