Part of the Western Corridor project, Johns Road (SH1) between Sawyers Arms Road and Harewood Road is to be four-laned with a raised median.
The Western Corridor (SH1) connects the northern and southern Canterbury areas with Christchurch International Airport, it runs between Belfast in the north and the large industrial area of Hornby in the south.
Increased commercial and industrial activity, particularly in Hornby and at the airport, is creating more traffic and congestion at peak times.
