The project is an integral part of Transit's overall strategy for easing traffic
congestion in central Auckland. It comprises new links, providing direct access
between the Northern Motorway, Grafton Gully, and the Port of Auckland.
Access to the lower CBD, Auckland Hospital, Mission Bay and Parnell has also
The project has met the needs of different types of motorists by increasing
route efficiency to the port and CBD and removing conflict between local
arterial and state highway traffic.
Specifically, the Grafton Gully Project has:
Extended the motorway to pass under Grafton Rd and into Stanley St,
removing the dogleg manoeuvre from Grafton Rd off-ramp to Stanley St.
Removed the dogleg intersection connecting Stanley St, Beach Rd, Parnell
Rise and The Strand, enabling direct access between Stanley St and The
Provided a new link from Wellesley Street to Grafton Road.
Widened Stanley Street and improved the intersections at Alten Road and
On average, 34,000 vehicles per day travel along Stanley Street (SH16).

Pedestrians and Cyclists
As well as benefits for motorists, there is improved cycle and pedestrian access
through and around Grafton Gully to Auckland Hospital, Parnell, The University of
Auckland and Auckland University of Technology as well as the Auckland Domain and
Grafton Gully is also part of the popular Coast to Coast walkway route, used by
many national and international walkers who annually experience the Auckland
isthmus by foot.
Previously a difficult area for pedestrians and cyclists to negotiate, Grafton
Gully has been transformed into a pedestrian and cyclist friendly area.
Crossing Stanley Street has been made easier by the installation of traffic
lights, some with a pedestrian phase. Other improvements include a signalised
intersection at Alten Road /Stanley Street and the new Tranz Rail bridge.
Crossing the gully has been made safer by the separation of local and motorway
traffic. Cyclists and pedestrians no longer have to compete with heavy motorway
traffic traveling to and from the Port.
Built as part of the project, the Grafton Road Bridge enables pedestrians to
safely cross the gully on an extra wide footpath while traffic exits the motorway
below the bridge.
During planning stages and throughout the project, Transit ensured the needs of
pedestrians and cyclists would be met by working closely with stakeholder groups
such as Walkable Communities and Auckland-based Cobley Walking Group.
The achievements of the Grafton Gully Project in the areas of archeology,
environmental management, design, traffic management, community relations and
project delivery have set a benchmark for projects of its type.
The project is the first of its scale to be constructed in an inner city
environment in recent times and has served as a model for future motorway
Transit, through Freeflow developed solid relationships with key stakeholders
including the Auckland Regional Council, iwi and neighbours to minimise the
negative effects of construction and maximise the opportunity for urban
Transit divided the project into three stages. The first two stages which are
complete and were designed to allow Stage 3 to be constructed at some time in
Involved upgrading the existing ramps in the upper gully and building a new
connection to Wellesley Street, with through traffic being directed below the
western end of Grafton Road.
Involved upgrading Stanley Street with traffic signals at Alten Road and a
free left turn into Beach Road which has been extended to pass below the
railway and link back into The Strand, removing the dogleg intersection.
The total cost of these first two stages was $68 million.
Transit will also seek a designation for Stage 3. This will be a sunken highway
parallel to Stanley Street which will provide a more direct link to The Strand.
This will be built later when there is sufficient traffic to justify its
