The NZ Transport Agency announced on Tuesday, 29 July 2014 the signing of a Private-Public Partnership (PPP) contract between the NZ Transport Agency and the Wellington Gateway Partnership for the 27km Transmission Gully project.
The 27 kilometre four-lane motorway will run from Mackays Crossing to Linden, through Transmission Gully. Four interchanges and two new link roads will connect the route to Mackays, SH58, eastern Porirua and Kenepuru. The Transmission Gully motorway is scheduled to be open for traffic in 2020.
More information about the project is available on the NZTA website.
