Interchange closures for Waterview project


The NZ Transport Agency says a series of planned overnight closures on Auckland’s busy Great North Road Interchange start next week for work related to the Waterview Connection project.

The closures begin on Sunday (5 July) so that heavy concrete Super T beams can be lowered into place on one of the ramps for the new motorway-to-motorway interchange the project is constructing at Great North Road.

“These Super T beams weigh between 55/65 tonnes and we need to close the interchange to live traffic so that we can do that work safely,” says the Transport Agency’s Highway Manager Brett Gliddon. 

The interchange closures affects:

  • those people travelling on Great North Road towards Pt Chevalier;
  • motorists who want to join the Northwestern Motorway (State Highway 16) city-bound;
  • or those wanting to use the Northwestern exit at the interchange, together with those coming from the Carrington Road/Pt Chevalier intersection, to drive along Great North Road towards Blockhouse Bay/New Lynn.

The closures do not affect people using the interchange to join the motorway westbound, or those westbound drivers leaving the motorway for Great North Road.  
“We are doing this work at night, and starting later, when traffic volumes are low to minimise any disruption to drivers and to those who rely on public transport,” Mr Gliddon says.  

The closures are spread over several nights from this Sunday until 30 July between 11pm and 5am

They are timed so that they will not affect morning and evening peak hour traffic, and no closures are planned for Fridays and Saturdays when weekend night traffic is heavier.

Detours will be in place to assist drivers.

The beams, which form the base for the roadway, are being placed on a section of Ramp 4, the highest of the interchange’s four bridges. Ramp 4 will carry traffic from the tunnels on to the Northwestern’s east or city bound lanes.
