Feedback is sought on proposed improvements to Auckland’s Southern Motorway (State Highway 1) between Papakura and Bombay.

It’s to support population growth along this busy corridor, the NZ Transport Agency (NZTA) says.

The project is one of the first from the Supporting Growth Programme and will enable new housing and business areas to be developed south of Auckland.

“Up to one million more people are expected to call Auckland home within the next 30 years, with the largest growth in South Auckland,” NZTA system design manager Brett Gliddon says.
“Significant new transport infrastructure is needed, which includes new and improved public transport, new walking and cycling routes and upgrades to the road corridors.

“Maintaining travel reliability through the area will create better access to employment, education and leisure opportunities as well as supporting national and regional economic growth.”

A new shared walking and cycling path is planned along the motorway’s western side, continuing one being constructed as part of the Southern Corridor Improvements Project.

The project will also focus on how the additional road space can be used to move people and freight in a smarter way, Gliddon says.

Lanes could be reserved for specific customers such as trucks carrying freight or vehicles with more than one person.

“We will also use intelligent transport systems, such as managed motorways and variable speed limits, to manage congestion and traffic flows.”

Public open days are on August 23, Drury Community Hall, 4pm-8pm; August 26, Pukekohe Town Hall, 10am-2pm; August 29, Ramarama School, 3pm-7pm.
Or feedback can be sent to nzta.govt.nz/p2b by 5pm on September 17.
