Second weekend of restrictions in place at Greville Road


The NZ Transport Agency thanks drivers for their patience and support last weekend during the closure of the Greville Road interchange on Auckland’s Northern Motorway (State Highway 1), and reminds them that the second weekend closure starts this Friday (17 October).

The closure starts from 9pm and will continue until 5am Monday (20 October).  The weekend restrictions are as follows:-

  • Northbound traffic exiting the motorway at Greville Road will be diverted down Tawa Drive to access Rosedale Road, Bush Road and Albany Expressway.
  • Northbound on-ramp at Greville Road will be closed.
  • No access to Albany Expressway from Greville Road or the motorway off-ramp
  • Southbound traffic exiting the motorway at Greville Road can only left turn.

There will be sign-posted detour routes.  The Transport Agency says local roads are also expected to be busy, and people using the detours should allow extra time to get to their destinations.

“We appreciate the support from drivers and local businesses last weekend, and we are counting on that again as we finish our necessary work at the interchange,” says the Transport Agency’s Highway Manager, Brett Gliddon.  “We ask people to be patient driving through such a large construction site, and to take care for their safety and the safety of our contractors.”

The interchange is being closed because of work related to the Transport Agency’s Upper Harbour Highway to Greville Road Northbound 3 Laning project – a series of improvements to both the motorway and local roads.

The project is constructing an additional northbound lane on SH1 between the Upper Harbour Highway and Greville Road interchanges, and switching the Greville Road/Tawa Drive/Albany Expressway roundabout into a fully signalised intersection.  It is also widening the southbound lane on the Albany Expressway from 1 to 2 lanes. There will also be a new shared walking and cycling path along both Greville Road and the Albany Expressway.

This weekend closure is a dependent on the weather.
