The CPB Contractors project involved the construction of Stages 5 and 6 of the Northern Road Upgrade, a major road infrastructure project in Sydney. Stage 5 was the 6.7 km upgrade between Littlefields Road and Glenmore Parkway, while Stage 6 was the section between Eaton Road and Littlefields Road. CPB Contractors was awarded the contract for both stages, and both are now completed.
