Worst summer in 30 years has 'minor impact' on Transmission Gully video

NZ TRANSPORT AGENCY

This fly-through, released in August 2016, starts at SH1 at Linden/Tawa and heading north around eastern Porirua to reconnect with SH1 at MacKays just north of Paekakariki.

Wellington's lousy summer is not expected to delay construction of the much-anticipated $850 million Transmission Gully motorway.

The 27 kilometre, four-lane motorway between the northern Wellington suburb of Tawa and McKays Crossing, north of Paekakariki, is scheduled to be completed by 2020.

Wellington recorded its worst summer in 30 years in 2016-17, but Wellington Gateway Partnership chief executive Sergio Mejia said the wet weather had caused minimal disruption.

"While there has been more wet weather over this summer than anticipated, overall there has been minor impact on the construction progress to date."

Work at the entrance to Kapiti for Transmission Gully, as it was in August 2016.

Drying out and stabilising of a large area of land around Mackays Crossing has been completed. This is where the motorway will link with the existing State Highway 1. 

Wainui Saddle: 

Ecologists have relocated fish from the Horokiri Stream, adopting the same methods used at Te Puka Stream. The fish have been moved to a similar habitat and will be returned once the new stream diversions have been constructed. 

Battle Hill Farm Forest Park:

Several culverts and bridges have been constructed, including the underpass that will provide access for Battle Hill Farm Forest Park users under the road. This will be open to the public soon, and the track that crosses the works will be re-routed through the underpass. 

State Highway 58:

Earthworks for the interchange with SH58 are under way in the Lanes Flat area. The permanent channel for the Pauatahanui Stream has also been opened.

Bulk earthworks have started behind Whitby and Cannons Creek, particularly at the James Cook interchange which will link the motorway to the Whitby and Waitangirua access roads. Excavation work has begun on the piers for the Cannons Creek Bridge.

State Highway 1:

Ranui pine harvesting is continuing at the southern end, as well as earthworks for bridges that will span the highway.

Sewer lines and other services in the area will soon be moved to allow for construction of bridge foundations and the interchange that will link to Kenepuru Dr.
