Leighton Contractors form part of an alliance to deliver the Ballina Bypass project for the Roads and Traffic Authority of NSW (RTA). The alliance includes the RTA, Maunsell AECOM, SMEC and Coffey Geotechnics to design and construct the bypass that will provide approximately 12.4km of dual carriageway as part of the 10-year Pacific Highway Upgrade Program.

The Ballina Bypass will stretch from South Ballina at the intersection of the Bruxner and Pacific Highways to just north of Ross Lane, Tintenbar. It will bypass a 19km section of the Pacific Highway and will serve to deliver significant improvements in road safety and reduce travel times. Overall the Ballina Bypass project will allow commuters to avoid the current five roundabouts, traffic lights and 60kph speed zones taking the highway traffic out of the urban area of Ballina.
