The project will provide better access in and out of Christchurch and this will in turn improve the economic well-being of the Canterbury Region and the wider South Island.
Planned growth in the Selwyn District (such as the Izone industrial park, and Rolleston) requires improved access to the Christchurch CBD, key employment centres and Lyttelton Port.
Without the project traffic on Main South Road is likely to double in the next 15 years, making access and crossing Main South Road very difficult and unsafe. The project will halve travel time between Rolleston and Christchurch at peak-times (from around 30 down to about 15 minutes). We also expect a 40% reduction in fatal and serious crashes.
The project will reduce the high traffic volumes on State Highway 1 (Main South Road) through Templeton by separating local traffic from traffic heading to Lyttelton Port and the central city. There will be 2000 fewer trucks a day.
Less traffic travelling through many local communities is also expected to improve accessibility and reduce noise, vibration and other potential effects from large volumes of traffic. The resulting improved highway and roading network will allow passenger transport to operate safely and more efficiently on Main South Road and Springs Road. Reduced traffic on many local roads will also improve conditions for pedestrians and cyclists, and allow the local councils to implement their own improved cycle strategies.
The project will increase employment, both during construction and as a result of improved access. It will also play a positive role in Canterbury’s earthquake recovery.
Hornby is one of the key industrial areas of Christchurch and the present (and future) congestion on roads in this area, such as Halswell Junction Road, means access for businesses in this area is difficult and inefficient. The project will help improve economic productivity through reduced transport times and costs. The construction of this project is also expected to create additional jobs.
