SH58 Safety Improvements

This page has information about the State Highway 58 safety improvements.

The NZ Transport Agency and Porirua City Council are working together to make State Highway 58 and adjoining roads safer for everyone who uses them.

Safety Improvements planned

  • Safer speeds: lowering the speed limit to 70km/h between the Postgate Drive and Pauatahanui roundabouts, and to 80km/h for the rest.
  • Separate traffic: Widening the highway between Dry Creek Quarry and Bradey Road, installing wire rope safety barrier between the opposing lanes of traffic and building a roundabout at Moonshine Road.
  • Widening and straightening curves between Mt Cecil Road and Harris Street: work is planned to improve safety on this section of the road. COMPLETE
