Auckland Southern Motorway - Future

Future

Several major projects are planned for the Southern Motorway within the next ten years (from 2008). From north to south they are:

• Newmarket Viaduct Replacement - The existing Newmarket Viaduct is six lanes wide, congested, and does not meet today's earthquake standards. Construction began in April 2009 on a new, seven lane structure. There will be one extra southbound lane (four in total) and three northbound with the capability to add a fourth lane in the future. The project is forecast to cost around NZ$215 million and completion is due by the end of 2012.

• SH1-20 East-West corridor linking the southern and western motorways between East Tamaki and Onehunga- Various investigations from the 1960s have reconfirmed the need for the link, the latest showing that if not completed by 2020, traffic in the area will be reduced to a crawl throughout most working days. Freight traffic volumes on local roads along the route are higher than on most state highways across New Zealand. The Eastern Corridor or AMETI (Auckland-Manukau Eastern Transit Initiative) to provide efficient access to the fast growing business and residential suburbs of east and south east Auckland. Multi-billion dollar economic benefits have been shown for this project. Currently the project is being built in small stages that stretch its completion out to the 2030s.
