The Ballina Bypass Alliance (BBA) was formed in July 2007 to design and construct a 12km dual carriageway as part of the Pacific Highway Upgrade. The BBA comprised Leighton Contractors, AECOM, SMEC and Coffey Geotechnics with the Roads & Traffic Authority (RTA). The Ballina bypass extends from south of Ballina at the intersection of the Bruxner and Pacific Highways to approximately 500m north of Ross Lane at Tintenbar. It includes major interchanges at Teven Road and Ross Lane, 19 bridges and a half interchange at Cumbalum and delivered significant improvements in safety and transport efficiency. Early works commenced in May 2008, with full construction commencing in June 2008. The northern section of the project was completed in March 2011, eliminating two black spots on the Pacific Highway including the notorious Tintenbar Hill. The southern bypass section of the project opened seven months ahead of schedule in November 2011.
