New Zealand Transport Agency (NZTA) is planning to construct the Petone to Grenada Link Road project in Wellington, New Zealand.

The project involves the construction of a four-lane road with two lanes running in each direction, a median barrier and the renovation of Petone intersection.

The project includes the construction of pedestrian ways, interchanges, and supporting walls, carriageways, service roads, and road separators and the installation of signal and safety systems.

In August 2014, NZTA released an engagement report following more than 1,400 public submissions on its plans for the link road. The submissions did not show a preference for either option C, which would widen the existing State Highway 1 through Tawa, or option D which would build a new road through the Takapu Valley to Transmission Gully.

NZTA received support and opposition for both C and D options.

However, the submissions largely support a new larger interchange at Petone and will be considered as a high priority over the rest of the link road project.

On November 17, 2015, the preferred route is confirmed i.e. through the Horokiwi Crest between Petone and Tawa, providing a four-lane link with extra crawler lanes on the Petone side.

NZTA is undertaking environmental investigations to assess preferred alignment. These will include ecological baseline surveys, including surveys of birds, bats, fish and vegetation, so that the design of the new route can minimize the impact on sensitive environmental areas.

Silva Ecology has been appointed as the study consultant for the project.

NZTA is refining the design of the route to submit consent applications by late in 2017. Design work is expected to commence once NZTA secures the funding approvals from the broad in 2018. Construction work is expected to commence in 2019 and scheduled to be completed by 2023.
