The State Highway 18 Hobsonville Deviation project is a 6 kilometre, four-lane motorway from the end of the Northwestern Motorway at Hobsonville Road to the western end of Upper Harbour Bridge in Hobsonville.
The Hobsonville Deviation Motorway provides an alternative to Hobsonville Road, to help reduce congestion and improve motorist and pedestrian safety. New interchanges have been built at Hobsonville Road, Trig Road, Brigham Creek Road and Squadron Drive. A new bridge at Clarks Lane for pedestrians and cyclists gives safe passage over the motorway. There is also be provision for future bus shoulder lanes.
The State Highway 18 Hobsonville Deviation and State Highway 16 Brigham Creek Extension project is part of the new Upper Harbour Motorway. The Upper Harbour Motorway has been under construction since 2006 to replace the current State Highway 18 that runs along Upper Harbour Drive and Hobsonville Road.
State Highway 18 Upper Harbour Motorway extends from the intersection of Upper Harbour Highway and Paul Matthews Road in the east, to the end of the Northwestern Motorway (State Highway 16) at Westgate in the west. It passes through the developing residential areas of Greenhithe and Hobsonville.
The motorway is being built in three sections – Greenhithe Deviation, Upper Harbour Bridge duplication, and Hobsonville Deviation. The last section of the motorway, Hobsonville Deviation, is now under construction and scheduled to be completed in September 2011.
