Barwon Heads Road is a north-south arterial road traversing the Armstrong Creek Urban Growth Area (ACUGA), connecting it to the economic hub of Geelong as well as tourism destinations along the Bellarine Peninsula and Surf Coast Highway. It plays a key role within the local and regional transport network, acting as a primary transport route for rapidly expanding communities within five discrete precincts, and a link to jobs, educational facilities and other services.

The Barwon Heads Road Duplication proposal seeks to duplicate a 4 km section of Barwon Heads Road between Settlement Road and Reserve Road. The proposal includes construction of a new bridge over the railway line at Marshall and remove the level crossing, upgrade multiple intersections, a shared path, new street lighting and road signage. The Australian Government has committed $292 million towards the $365 million project.
