In the 1961 Brisbane City Council Town Plan, the concept of a northern suburbs' expressway between Bowen Hills and Aspley was first proposed. The expressway would travel along the eastern side of Lutwyche Road to Park Road at Kedron, take a northerly route to Chermside and through the eastern side of Aspley, before heading north-westerly through Carseldine to connect with the Bruce Highway north of Bald Hills. The 1965 Wilbur Smith and Associates Brisbane Transportation Study recommended the additional construction of a Northwest Freeway between the Brisbane CBD and Aspley via the Grange and Everton Park.
